Good Morning FrugalRepair, Please how can i repair hisense curve 60inch screen that suddenly developed vertical lines, which start from middle and moves to the left side. i want to learn .
I just got a 75 inch vizio off the curb. Black lines ugh. I followed your directions and cleaned contacts..... works like new! Thank you for the video. Definitely thumbs up.
I'm from Sri Lanka and I have a 65-inch TV. I experienced the same issue shown in your video. The repair person asked me to pay $550, but I fixed it as you suggested. Thank you very much for helping me save my money.
If I can figure out a way to fix that tab bond, I’ll definitely show it. I’ve had some minor success by cutting into the cable at an angle and then dragging a soldering iron (with solder) across it.
I'm a new subscriber from Canada. I've been watching your videos and I couldn't thank you enough for the insights and skills I've learned. People like you who share their skills and knowledge for free so others can benefit will forever remembered. Keep up the good work!
Just wanted to let you know that your channel inspired me to repair my patio tv instead of buying a new one. Ended up being the led driver board. I’m pretty handy but electronics intimidated me until I came across your channel. Thanks for what you do!
FINALLY an expert for problems like this. I mostly see videos that gives you solutions which are completely useless. This video covers the 'why does this happen' and 'how to fix it' very well. Love it!
Through your knowledge I've been able to fix my telly and to be truthful you're one hell of a guy thank you ever so much for your information more power to your brother
wow! after watching your video i was able to fix the vertical lines on my 12yr old workout room TV. i was about to replace it. ty so much for taking the time to share the knowledge. edit: i stuck tape almost exactly where you did. pressure was needed.
Glad I discovered this video. Also happy you mentioned the horizontal lines even in passing but i wish to see it discussed in further detail hopefully in another video.
In many cases you can successfully reattach the bond contacts by using a hot bar. Besides the contact surfaces being a little bit sticky themselves, there's adhesive between the contact surfaces which is activating when heated to safely keep the ribbon in place. There are temperature-regulated soldering irons that have large bar-shaped tips to put heat onto a large surface. That would be the best-controlled approach but also the most expensive. The edge of a laundry iron might also do the job as you don't need excessive heat, only around 180°C or so. If you are really careful you can even do this reattachment while the LCD is being powered so you can immediately see the success.
They say you’re supposed to learn something new every day and you, sir, have been my Sifu! I’m gonna get started right now. I’m checking those connection issues. Thanks again.

A big thank you! My 2017 LG TV recently developed horizontal lines across the bottom third with some parts of the image from the top third repeated at the bottom. I isolated the side that had the issue and taped the first 8 pins and the picture was perfect. I left it as such and I can't tell any difference. Should I leave it or try to reduce the lines blocked? Also this TV seems to have the t-con built into the main board. I don't mind replacing the board if that will make for a better fix. Thanks again. Your content is very useful.

Thank-you for your TV repair videos. It allowed me to mostly fix my 75" QLED Samsung. TV was cycling from on to off. Replaced the power board. But still have a single multicolor vertical line. Have cleaned several times the the T-con ribbon cable connectors plus done resets, made sure software was updated and line appears on all inputs. So I am thinking the Main/T-con board got damaged when the power board faulted. Does that make sense?
How about warming the ribbon connection with a heat gun and applying pressure as it cools (one half, then the other, to avoid dislodging)? Might that soften the adhesive enough to re-establish the connection (even for solder)?
Thanks for the info, i have a LG47la4700 and it has those vertical lines, i will try your methods, and if you have any more info i can try i would appreciate seeing it Thanks
You sir are a great teacher I will learn and save diy on most repairs thank you all I will recommend your channel to everyone!!! May God bless you all families 😊
Very informative video. Have a similar issue, when watching the TV for 2-4 hours, a entire column 2" wide will draw itself top to bottom. I am assuming it is due to a heat related issue. This is an ancient TV, one of the original Hatachi 42 HD plasma tv's. 2006. Turn it off, let it cool down and its fine again for another 2 to 4 hours. Had it apart to replace the power board a few years back.
Very interesting. I have vertical lines on 82 inch tv. We found that chips-on-film are very hot on good segments. The chip on ribbon with the problem is NOT hot. Need to diagnose is T-Con board causing the issue or chip-on-film bad itself. Woruld be great to get some ideas
If there is a failure in the COF, then I doubt you want to attempt a repair on that (assuming you could get a replacement part) due to how small and sensitive that cable is
Great video and well explained. I have a 27in HP monitor and the power adapter went out. I bought a replacement on Amazon and when it arrived I plugged it in and it worked. I run dual monitors on my PC, with the HP using the HDMI port, and my second one using the DVI port. I used it all day long with no issues and turned it off that night. Next morning, the HP monitor powered on, but no picture. I removed the second monitor and used the DVI port and same thing. Powers on, but no screen. I disconnected the HP from the PC and turned it on, I could see screen light up and then see the message No Signal since nothing was connected to it. Then after a while it shows going to sleep mode. Why is the HP not getting signal to turn on with the pc?
Thanks for watching! I’m not sure why it wouldn’t be accepting the video input. If the only variable that changed from when it was working before was the new power supply, maybe that is the culprit? Have you measured the voltage of its output versus the spec input ratings on the monitor? I doubt it would be an issue but might be worth checking.
@@FrugalRepair Sorry just seen the reply. Thanks for that. I did run a multimeter on it and im getting the right voltage. I thought it was my video card, but I used the connectors on the other monitor and they work on it. Just weird how it worked the first day and now it wont power show signal from the pc.
Great Video. Start getting me watching repairing video. I bought a Pioneer TV (PN43951-22C) a year ago. But it won't start again now. Trying to look up some TV repairing videos online. Wondering would you have any idea what could help me. Thanks!
Hope you can get it fixed. I hopefully have enough videos on the topic (plus the free e-book) to get you started. You might want to start with the video on what to do if your tv experiences a power surge.
I have a friend who is a repair man and he shared one time he felt like especially lcd/led TV are designed to have a problem for past a year because how easily the way it was easy to loosen or degrade something inside them and add to the fact that most thing he repairs are LCD/LED TV the ones that has average or lower prices. He says its better to pay expensive led/lcd TV because those things will last longer and the money and time you spent for repair for non-expensive lcd/led are just better spent on expensive lcd/led tv.
In general you might get what you pay for. But even the big brand names have had strings of problems. Samsung and Sony had years of their TVs having significant issues. Vizio sometimes has a bad reputation but a lot of their TVs were made by LG.
Interesting...I have 10 years old LG and is still working flawless was low price range. Another Philips high range price also 8 years old have vertical lines.
great video, if the vertical line on my screen has a moving pattern to it, would that mean its a problem with the data signal to that row of pixels? when up close it looks like its white and red pixels moving downwards.
Thanks. I'm not sure I can exactly envision it but it could be a problem on the vertical line but the other 2 lines for the pixel (there are three RGB) are still working so it's trying to show the image and perhaps that is what oyu are seeing? It is possible it is the tcon board, however.
would it be in any way bad to take off the tape that is covering the ribbons (trying to see if my issue is with the ribbons on my monitor as nothing else has worked)
I am very happy to meet this lesson !!!!!! can I ask one question only FR ? is there a possibility for cracking on the screen glass with out external impact ? if your replay is yes , pls , explain me the invisible engineering that cause to cracking on glass of LEd / LCD Tv screen . Thanks ! stay well .
They ended up giving me the tv and I haven't worked on it yet. My guess is the tape trick will work since it seems like a row signaling issue. Have you seen the videos about the tape trick?
Thanks! I'm gonna try this with an LG tv i found in the trash 😁 Edit: It didn't work for me, but while dissasembling i found a yellow tape stuck in the ribbon cable thatwas covering few of the pins, after taking it out 90% of the lines weere fixed! I will try the toothbrush trick once i will have to clean out the display inside, due to some bugs and dust being trapped in there.
What if the lines are the exact same way but horizontal. Would I be able to use the same methods that you just used in this video to fix the horizontal line issue on my screen ??
Have you seen horizontal lines, on an LG 65" OLED? The lines are on the left (roughly 1/4 of the screen) but they are dancing? Sort of going on and off or acting like a changing graph line. Can you open the back, inspect the T-Con boards, swap the connections to see if the problem changes?
This is exactly what happened to my Samsung Smart TV. A single vertical line on the screen which I think was caused due to spraying glass cleaner on the screen. Now I have to open it up and figure out a way to fix it :). Thanks for the video
I've got vertical lines too and looks like there was some liquid ingress right where those ribbons enter the LCD itself. I don't see how I can clean there but I'm sure it's what's caused the lines as the ingress is right around where the lines are
if alcohol doesnt work, try wd40 and a paint brush instead. it has softer bristles and will will easily go in tight spaces. DO NOT GET WD40 ON THE ACTUAL SCREEN, IT WILL CHEW INTO THE ADHESIVES AND RUIN THE PANEL. a drop or 2 on the driverboard on the rusty spot will be just fine.
Hi, I have a 50 inch Hisense Android tv, 50H8G, board number 261423, 261424, RSAG7.820.9615/ROH and I was wondering if there was a bios chip on it. If not, what component on the board does the firmware write to. If it wrote to an Ic chip then I could unbrick my TV and write directly to the IC. My TV has a white light of death after an update and I tried all fixes and nothing works. Thanks
Hey! I’m having vertical lines on my LG monitor too. Mine are thicker and are bands of multicolor lines though. Any tips on what I should look into? I bought it off eBay and the ad mentioned it was “rasterized” thanks in advance
You mentioned lines going away when the tv warms up. What if you have the opposite problem where the thick bands show up once the tv has been on for about 15 seconds?
You mean you have a good picture and in 15 seconds or so, the problems show up? That still sounds like a heat related issue and hopefully you can fix it with some non-conductive material under the metal bracket to put some gentle pressure on that tab bond. You can try turning down the LED brightness to something like 10% and see if the tv lasts longer (less heat in the tv). Or you can put a fan on the tv with the cover off and see if it lasts longer to isolate the problem as a heat issue.
Might a hot air gun at a bit of a distance not repair the poor connection in that ribbon cable if the pencil eraser trick seems temporarily successful? Thank you for the useful video!
I have large grey bars. Do you think this would help with that? If not whats the name for the big grey bars because I can't find people having the same issue
@FrugalRepair Do you have any idea why OEM place those connectors at the bottom of the LCD panel instead of top? Is this to "design failure mode" anytime something spills on the panel? If those connectors would be at the top, gravity would be not helping OEMs
Just found this video and your channel. I just recently have gotten what seems to be a tiny bug or piece of dust trapped between the front screen and whatever produces the pictures. While looking around RUclips for a way to just separate the front and wipe the thing away it appears that doing that is a huge project and not a simple thing. Any ideas? I tried gentle tapping to see if it would release and fall, but it didn't work.

Hello. I have like vertical lines, but only in the bottom of the TV. There is like a 5cm stripe with vertical lines. Any idea what the problem might be, and how to fix if there is a way to fix. Thank you.
Hi, i like ur video, very detailed. I have 65 inches 2021 Oled LG Tv. I moved location and I received the tv after about 4weeks later and i turned it on, it comes on once and went off and never came up again But the res light xomes yo when its plugged. Then there arw horizontal lines at the extreme right of the tv. Pleaae what do you advice. Thank you
Samsung 60 inch, Thin Screen Model No. QN65Q60BAF In the process of moving the TV my friend grabbed the TV leaving a bubble imprint on the right bottom corner of the TV now the TV shows only on the left side and still has the small bottom edge bubble imprint. Any suggestions would be appreciated.
I'm not sure exactly what the damage could have been. I'd try to re-seat the cables that go to the driver boards and hopefully that is it. But it's also possible the lcd is damaged beyond repair.
Would using vinegar on the strip maybe dissolve the corrosion, or would that dissolve the bond between the ribbon? Also could hot air or a heat gun maybe rebond it? Or would that melt the ribbon?
I don't know what vinegar would do to the adhesive or the ribbon. I don't think you would want to put something acidic on a pcb anyway. Good thought on heat, I've not had success applying heat to these tv tab bonds so it's possible it could work. I would try to use something more like a soldering iron than a heat gun.
@@FrugalRepair The vertical line issue presented here is very similar to an issue that occurs on game boy screens. The fix there is to apply heat onto the ribbon using a soldering iron.
Excellent video! Thanks for all the information! I do have an idea though. Have you tried dragging the soldering iron on the flex cable connection to the board? That's actually how you fix vertical lines on a Game Boy screen. If you do it for short periods of time, the flex should be able to handle the heat.
have you ever tried it? It's really easy to melt the ribbon plastic if your heat isn't perfect. (pre-heath the board, if you're going to attempt this.)
Big fan sir Love your work I have this 55 inch Samsung led That has what its seems to be horizontal line I have a short video If i may share it with you Can you help me out Thanks in advance
If it doesn't conduct electricity you should be good. You can even cut the ribbon cable and bend back the pins but I've found the scotch tape is the easiest to work with.
hi need help bro about oled lg cx 55 have a horizontal white stripe (i can leave with it) at bottom so my concern and question if this tv will get worse over time or risk to stop working !? i need answer plz thank you
Good Morning to you guys... Please i have a hisense curve 60inch screen that have some vertical lines , How can it be resolved... i am opened to more knowledge.
The lcd technology is similar so it would depend on the damage to the lcd. IPA won't hurt the lcd. Just down pull the tabs off the driver board or damage them.
What if my TV looks perfect for 10-90 seconds and then it gets horizontal and vertical lines, then goes back to being perfect? I'm searching online but this video came up instead.. Okay so I just removed the back panel. Every time it goes all static-y with the lines, I hear a buzzing. Does that indicate anything that you're aware of? If I get no response it's fine, but if you do, thanks for your time
I don’t really know but sounds like a bad connection somewhere. I hope it’s not the tab bond but you can do the trick of putting pressure on it with something non-conductive. It may be working well then stop because of heat. You can try disconnecting one of the cables from the tcon board (did you watch my fixing with tape videos?) and try to isolate which driver board might have the faulty tab connection
30 minutes ago my 47lg70ug just went fuzzy. The menu screens seem completely clear, but no matter what input i change it to, ps4, antenna, xbox the picture was bad. I just swapped TV's for now but I'm going to try this in the next 3 weeks i have off of work. Thanks
Hi.....I tried the tape on my vizio tv original t con card wires . Did not repair the horizontal lines and the flickering . Changed to a new t con card and now I only have horizontal lines on the top of the tv only . Any help would be appreciated .
I have this exact same TV but it's the 42" version and if I leave it turned off for any length of time, when I turn it back on, only the top inch or two of the display will show a proper image, the rest of the display will be blank, after leaving it on for 10-15 minutes, I can turn the TV off and back on and it will start working again... I keep expecting the TV to die but it has worked in this state for a few years now... Any idea what could be happening...?
Do you have repair videos for LG OLED TVs? I have a LG 55EC9300 with broken HDMI ports. I got a used main board & had it installed by a TV repair guy. The used board was bad & TV didn’t turn on. The original board was put back in but picture has 2 wide snow bars & 2 wide black bars. TV guy pushed on back panel & they went away but a minute later came back stay on all the time. Any suggestions? ShooJimmy doesn’t have the board. LG wants $310 for new board & $332 for refurbished one.
It’s possible any issue could happen if you are talking about cracked or lifting solder connections under a chip. Those usually would be found on the cpu on the main board. I tried to cover the typical reasons for vertical lines in the video.
I have a 50inch webos powered rca, I was having horrible distorted image and lines.i unplugged the right ribbon cable, and a had half a screen white and the other with 90 mostly clear image. I did the tape method on ribbon cable and the distortion went away along with most of the lines. No matter how I taped the cables the lines were there. I replaced the tcon board and the lines a lot less visible (95%) repaired now. I wonder if my problem is more the ribbon cable/connection?
I have the same issue as the friend that sent you a picture, what is the cause of this? It came out of nowhere and the tv is only about a year old. Im really confused as to why it happened

@@FrugalRepair Sorry just seen the reply. Thanks for that. I did run a multimeter on it and im getting the right voltage. I thought it was my video card, but I used the connectors on the other monitor and they work on it. Just weird how it worked the first day and now it wont power show signal from the pc.
Great Video. Start getting me watching repairing video. I bought a Pioneer TV (PN43951-22C) a year ago. But it won't start again now. Trying to look up some TV repairing videos online. Wondering would you have any idea what could help me. Thanks!
Hope you can get it fixed. I hopefully have enough videos on the topic (plus the free e-book) to get you started. You might want to start with the video on what to do if your tv experiences a power surge.
I have a friend who is a repair man and he shared one time he felt like especially lcd/led TV are designed to have a problem for past a year because how easily the way it was easy to loosen or degrade something inside them and add to the fact that most thing he repairs are LCD/LED TV the ones that has average or lower prices. He says its better to pay expensive led/lcd TV because those things will last longer and the money and time you spent for repair for non-expensive lcd/led are just better spent on expensive lcd/led tv.
In general you might get what you pay for. But even the big brand names have had strings of problems. Samsung and Sony had years of their TVs having significant issues. Vizio sometimes has a bad reputation but a lot of their TVs were made by LG.
Interesting...I have 10 years old LG and is still working flawless was low price range. Another Philips high range price also 8 years old have vertical lines.
great video, if the vertical line on my screen has a moving pattern to it, would that mean its a problem with the data signal to that row of pixels? when up close it looks like its white and red pixels moving downwards.
Thanks. I'm not sure I can exactly envision it but it could be a problem on the vertical line but the other 2 lines for the pixel (there are three RGB) are still working so it's trying to show the image and perhaps that is what oyu are seeing? It is possible it is the tcon board, however.
would it be in any way bad to take off the tape that is covering the ribbons (trying to see if my issue is with the ribbons on my monitor as nothing else has worked)
Excellent service
Is vertical lines the same we horizontal lines. Aask is the same way to repear?.
It usually means something else. Watch my tape fixing videos for the explanation
I am very happy to meet this lesson !!!!!!
can I ask one question only FR ?
is there a possibility for cracking on the screen glass with out external impact ? if your replay is yes , pls , explain me the invisible engineering that cause to cracking on glass of LEd / LCD Tv screen . Thanks ! stay well .
I have the exact same problem like your friend at 1:14. What did he do to fix this problem?
They ended up giving me the tv and I haven't worked on it yet. My guess is the tape trick will work since it seems like a row signaling issue. Have you seen the videos about the tape trick?
i have, i will try that soon@@FrugalRepair
Thanks! I'm gonna try this with an LG tv i found in the trash 😁
Edit: It didn't work for me, but while dissasembling i found a yellow tape stuck in the ribbon cable thatwas covering few of the pins, after taking it out 90% of the lines weere fixed! I will try the toothbrush trick once i will have to clean out the display inside, due to some bugs and dust being trapped in there.
What if the lines are the exact same way but horizontal. Would I be able to use the same methods that you just used in this video to fix the horizontal line issue on my screen ??
Watch my videos on fixing with tape for horizontal lines. It’s easier to correct than vertical lines.
1:09 I have the same issue here and I tried the tape method but it didn't work.. any suggestions?
Have you seen horizontal lines, on an LG 65" OLED? The lines are on the left (roughly 1/4 of the screen) but they are dancing? Sort of going on and off or acting like a changing graph line. Can you open the back, inspect the T-Con boards, swap the connections to see if the problem changes?
This is exactly what happened to my Samsung Smart TV. A single vertical line on the screen which I think was caused due to spraying glass cleaner on the screen. Now I have to open it up and figure out a way to fix it :). Thanks for the video
I've got vertical lines too and looks like there was some liquid ingress right where those ribbons enter the LCD itself. I don't see how I can clean there but I'm sure it's what's caused the lines as the ingress is right around where the lines are
if alcohol doesnt work, try wd40 and a paint brush instead. it has softer bristles and will will easily go in tight spaces. DO NOT GET WD40 ON THE ACTUAL SCREEN, IT WILL CHEW INTO THE ADHESIVES AND RUIN THE PANEL. a drop or 2 on the driverboard on the rusty spot will be just fine.
Will this be the same for an OLED tv?
Hi, I have a 50 inch Hisense Android tv, 50H8G, board number 261423, 261424, RSAG7.820.9615/ROH and I was wondering if there was a bios chip on it. If not, what component on the board does the firmware write to. If it wrote to an Ic chip then I could unbrick my TV and write directly to the IC. My TV has a white light of death after an update and I tried all fixes and nothing works.
Thanks
I opened my tv to fix the vertical green line. Should the COF be hot when the tv is on?
Hey! I’m having vertical lines on my LG monitor too. Mine are thicker and are bands of multicolor lines though. Any tips on what I should look into? I bought it off eBay and the ad mentioned it was “rasterized” thanks in advance
If one of my yellow connectors/wire is damaged. Is it possible to repair or do I need a new screen?
If you mean the yellow wires that have the tab bond on the driver board then no, you realistically can’t fix that, unfortunately.
You mentioned lines going away when the tv warms up. What if you have the opposite problem where the thick bands show up once the tv has been on for about 15 seconds?
You mean you have a good picture and in 15 seconds or so, the problems show up? That still sounds like a heat related issue and hopefully you can fix it with some non-conductive material under the metal bracket to put some gentle pressure on that tab bond. You can try turning down the LED brightness to something like 10% and see if the tv lasts longer (less heat in the tv). Or you can put a fan on the tv with the cover off and see if it lasts longer to isolate the problem as a heat issue.
Might a hot air gun at a bit of a distance not repair the poor connection in that ribbon cable if the pencil eraser trick seems temporarily successful? Thank you for the useful video!
Heat might be helpful with the adhesive but it’s the corrosion underneath that is the issue.
Amazing..thank you..i will try repair my monitor after this..
I have large grey bars. Do you think this would help with that? If not whats the name for the big grey bars because I can't find people having the same issue
I have a VIZIO D32fM-k01 - I need to order a power board. can you make a recommendation on where to source it?
@FrugalRepair Do you have any idea why OEM place those connectors at the bottom of the LCD panel instead of top?
Is this to "design failure mode" anytime something spills on the panel?
If those connectors would be at the top, gravity would be not helping OEMs
I don’t think there’s much significance to it because sometimes the tabs are at the top.
Why don't you try the GamBoy LCD fix with a soldering iron? It will pretty much work in the long run. I did this already on a TFT years ago.
Great buddy, thanks, good luck !
Just found this video and your channel. I just recently have gotten what seems to be a tiny bug or piece of dust trapped between the front screen and whatever produces the pictures. While looking around RUclips for a way to just separate the front and wipe the thing away it appears that doing that is a huge project and not a simple thing. Any ideas? I tried gentle tapping to see if it would release and fall, but it didn't work.
My tab bond is tore across ... is there a replacement that can be bought and installed?
No, unfortunately you won’t be able to repair that.
Not to change the subject, but vertical or horizontal slots in your light switch wall plate screws? 2:10 Had a hard time focusing after that, NGL
LOL, that scene I think I grabbed from stock footage. You have a great eye for detail!
@@FrugalRepairI did wonder if it was actual footage of you or family/friend lending their hand😂Orientation matters! You have a wonderful talent and I truly believe you’ll be blessed for sharing that knowledge with the world!
I have a 65up7670puc LG TV.
I broke the screen. Do you know a website I can buy the part my self?
Thanks..... Very useful video.... 👍
hi! The picture your friend sent you in this video, I have that same tv and that same issue with mine. How would you go about fixing this problem?
Hello.
I have like vertical lines, but only in the bottom of the TV. There is like a 5cm stripe with vertical lines. Any idea what the problem might be, and how to fix if there is a way to fix.
Thank you.
Good luck sir 🎉
Hi, i like ur video, very detailed. I have 65 inches 2021 Oled LG Tv. I moved location and I received the tv after about 4weeks later and i turned it on, it comes on once and went off and never came up again
But the res light xomes yo when its plugged. Then there arw horizontal lines at the extreme right of the tv. Pleaae what do you advice. Thank you
Samsung 60 inch, Thin Screen Model No. QN65Q60BAF
In the process of moving the TV my friend grabbed the TV leaving a bubble imprint on the right bottom corner of the TV now the TV shows only on the left side and still has the small bottom edge bubble imprint. Any suggestions would be appreciated.
I'm not sure exactly what the damage could have been. I'd try to re-seat the cables that go to the driver boards and hopefully that is it. But it's also possible the lcd is damaged beyond repair.
Do you have a video on reseatting the Driver Board cables?
Would using vinegar on the strip maybe dissolve the corrosion, or would that dissolve the bond between the ribbon? Also could hot air or a heat gun maybe rebond it? Or would that melt the ribbon?
I don't know what vinegar would do to the adhesive or the ribbon. I don't think you would want to put something acidic on a pcb anyway. Good thought on heat, I've not had success applying heat to these tv tab bonds so it's possible it could work. I would try to use something more like a soldering iron than a heat gun.
@@FrugalRepair The vertical line issue presented here is very similar to an issue that occurs on game boy screens. The fix there is to apply heat onto the ribbon using a soldering iron.
Excellent video! Thanks for all the information! I do have an idea though. Have you tried dragging the soldering iron on the flex cable connection to the board? That's actually how you fix vertical lines on a Game Boy screen. If you do it for short periods of time, the flex should be able to handle the heat.
have you ever tried it? It's really easy to melt the ribbon plastic if your heat isn't perfect. (pre-heath the board, if you're going to attempt this.)
can I fix it in the monitor also
TV and computer monitors are basically the same. A monitor may only have one cable going to the lcd assembly though.
Big fan sir
Love your work
I have this 55 inch Samsung led
That has what its seems to be horizontal line
I have a short video
If i may share it with you
Can you help me out
Thanks in advance
Can I use masking tape instead of scotch tape?
If it doesn't conduct electricity you should be good. You can even cut the ribbon cable and bend back the pins but I've found the scotch tape is the easiest to work with.
How do you fix the lines like the one your friend sent? My tv looks exactly like that one at the beginning of the video
on my jvc tv i am having the same horizontal issue as your friend with the vert lines from what is displayed like at 1:08 to1:17 in this video
I’d suggest watching the videos I made about fixing horizontal lines with the tape trick
hi need help bro about oled lg cx 55 have a horizontal white stripe (i can leave with it) at bottom so my concern and question if this tv will get worse over time or risk to stop working !? i need answer plz thank you
Hi i just turned on my tv and noticed a 3 inch vortical green line on the right hand side of my tv rest of the tv looks fine is this fixable
Good Morning to you guys... Please i have a hisense curve 60inch screen that have some vertical lines , How can it be resolved... i am opened to more knowledge.
Could the original short have caused some of the problems in the form of heating?
Can this work for a laptop?
The lcd technology is similar so it would depend on the damage to the lcd. IPA won't hurt the lcd. Just down pull the tabs off the driver board or damage them.
Curious if you might have a spare Vizio 91.74Y10.002G mainboard? I can't find one anywhere. 🤔
What model is that from?
Simplicity at next level 🤝🏻👌🏻
What if my TV looks perfect for 10-90 seconds and then it gets horizontal and vertical lines, then goes back to being perfect? I'm searching online but this video came up instead..
Okay so I just removed the back panel. Every time it goes all static-y with the lines, I hear a buzzing. Does that indicate anything that you're aware of? If I get no response it's fine, but if you do, thanks for your time
I don’t really know but sounds like a bad connection somewhere. I hope it’s not the tab bond but you can do the trick of putting pressure on it with something non-conductive. It may be working well then stop because of heat. You can try disconnecting one of the cables from the tcon board (did you watch my fixing with tape videos?) and try to isolate which driver board might have the faulty tab connection
30 minutes ago my 47lg70ug just went fuzzy. The menu screens seem completely clear, but no matter what input i change it to, ps4, antenna, xbox the picture was bad. I just swapped TV's for now but I'm going to try this in the next 3 weeks i have off of work. Thanks
Can you repair if the vertical lines are caused by a crack ?
If the LCD is cracked, then you will not be able to fix it. Only replacing the LCD is the option (but they are near impossible to get).
Indeed its a helpfil tips
Does this work for a tv where the whole screen is filled with yellow and red vertical lines and other colored horizontal lines ?
Hi.....I tried the tape on my vizio tv original t con card wires . Did not repair the horizontal lines and the flickering . Changed to a new t con card and now I only have horizontal lines on the top of the tv only . Any help would be appreciated .
My tv is on the fritz can you help I can se d a video I.just want to know if I could fix it myself
I have this exact same TV but it's the 42" version and if I leave it turned off for any length of time, when I turn it back on, only the top inch or two of the display will show a proper image, the rest of the display will be blank, after leaving it on for 10-15 minutes, I can turn the TV off and back on and it will start working again... I keep expecting the TV to die but it has worked in this state for a few years now... Any idea what could be happening...?
How can you fix the verticle line if the COF is cut in a small area of the ribbon portion?
Thanks for information
How about if the screen looks like it leaked ink and has a crack point but doesn’t actually on the surface. The backlight works though.
That likely means the LCD is cracked and the LCD is not repairable.
Got horizontal lines and yea my tcon is in the main board also but its like kinda solder to be connected with the power supply board
Do you have repair videos for LG OLED TVs? I have a LG 55EC9300 with broken HDMI ports. I got a used main board & had it installed by a TV repair guy. The used board was bad & TV didn’t turn on. The original board was put back in but picture has 2 wide snow bars & 2 wide black bars. TV guy pushed on back panel & they went away but a minute later came back stay on all the time. Any suggestions? ShooJimmy doesn’t have the board. LG wants $310 for new board & $332 for refurbished one.
Thanks so much the video and information where very helpful.
Thanks for watching!
i thought it was on the chip that causes it to make a vline. is it posible to put heatsink and fan to that mobo?
It’s possible any issue could happen if you are talking about cracked or lifting solder connections under a chip. Those usually would be found on the cpu on the main board. I tried to cover the typical reasons for vertical lines in the video.
I have a 50inch webos powered rca, I was having horrible distorted image and lines.i unplugged the right ribbon cable, and a had half a screen white and the other with 90 mostly clear image. I did the tape method on ribbon cable and the distortion went away along with most of the lines. No matter how I taped the cables the lines were there. I replaced the tcon board and the lines a lot less visible (95%) repaired now. I wonder if my problem is more the ribbon cable/connection?
Does this apply to a Sony a80j? I have a single blue line that goes away or get brighter when I move/ put pressure on it
Yes, it would be basically the same since it’s lcd
I have the same issue as the friend that sent you a picture, what is the cause of this? It came out of nowhere and the tv is only about a year old. Im really confused as to why it happened
I have a 50 inch kodak smart tv. The tv screen get lines all over screen sometimes and when i turn of and on it goes away. Any clues boss?
Love that you share this
