Thx for the vids. I actually have a 55inch LG led TV I need to change power supply board on. Uncle was messing with breaker box and fried it, smh. Ugh, dnt think the main board was damaged, by the looks of it anyway. And can see a few smaller bad spots on power supply. Just hope I get the right part. Light does come on some, but no pic, basically like TV is off. Hopefully it didnt get to main board. I'd think their would be something showing main board is messed up somewhere, but their isnt. Power supply has a cpl capacitors dome shaped on it, and a cpl darkish spots so looks to just be power supply. Fingers crossed. TV getting older hopefully can still get the part I need. Thx for your vids. Need my bigger TV back! Lol

Thanks again & please post more such useful video clips in future. 👍
The unplug/ replug option worked, thank you! I bought a used TV months ago and only tested it once with the seller, brought it home and then put it into storage. Today I finally plugged it in and it had a standby light but a black screen. I thought I'd bought a dud but no! Cheers, you saved me a lot of grief :)
Thanks for posting this, Tampatec! I live in Wyoming where there are ZERO TV repair shops, so I have been learning about LCD/LED technology so I can repair people's TVs in my hometown
I'm so amazed by your talent of impeccable technical skills (so genuine). I've recently encountered a Hisense Smart LED television dilemma and in search of an inexpensive repair, I began watching RUclips videos. My Smart TV will not power on, the standby light has a continuous red blinking light. I’ve attempted the unplug and re-plug outlet trick (still) red blinking light nightmare. I’m an elder lady confused; some videos explain replacing the Main Board, while others mention for Power Board replacement. I need your technical expertise and advice should I replace the Main Board or the Power Board. Please Help, this elderly lady is in desperate need of her TV while laid up with back injuries. Thank you, TampaTec
You are awesome bro! Your videos have helped me tremendously. I have a LG 49UJ6200...No power, no sound, and I think it doesn't have a stand by light at all. I've done the dark room and flashlight method and didnt see any images or backlights. I replaced the power board. I dont get any voltage on the terminals marked as P/ON, P-Dim and INVON. Do you think the logic board AND the LED lights are bad? Also, what should voltage be on the LED terminals/plugs?

I’m a retired electronics engineer. Worked for bombardier designing in train audio/ digital systems in England, mainly pcb designer.

Waiting30 seconds really helped, had the tv and Xbox plugged into the same dual wall socket, took the Xbox our first and then the tv. Waisted 30 seconds and then turned tv back on first and worked like a charm thankyou
My tv was stuck in standby mode for 2 weeks-I tried everything suggested on the internet..finally I took the plug and put it in and out of the socket rapidly-on the second or third "in" the electricity "popped" and the red light turned green. The electrical "jolt" jolted it out of standby. Fixed.
Thank you Tampatec for a very helpful video, I have an RCA Model: SLD32A30RQ (no display with standby) When I turn on the tv the backlight has a light and stays for about 15 seconds (but no display) but has a standby.

Tampatec, thanks very much for your videos, they're terrific. I have a problem with a Sony Bravia (KDL-46HW800). It turns on, is fully functional and has a perfect picture for 5-10 minutes. After that time, it abruptly shuts down. The red light blinks 6 times. I've replace the power board but that didn't repair the issue. Any advice would be great. Thanks!
Hi by the way i like the videos you post up on Tv's and been learning how to fix an hdtv. My question is that I'm having trouble with an LG 55lk520 (55inch tv) and had the power supply replaced, main board, backlight inverters. Power supply might have pins messed up connected to the main board and was wondering if thats the problem from not powering up?
THANK YOU FOR YOUR HELP BECAUSE I HAVE A KARAOEKE WITH MONITOR THAT IS NOT CONSISTANT,SO IM GOING TO REMOVE THE TCON CIRCUIT BOARD TO SEE IF MY IPOD WILL PLAY A MOVE FROM THE DOCK.
Hi Tampatec and thanks for the vids. I have a Sony KD-65X9000B that now blinks 4 times with no other response. I've pulled it apart and have measured the voltage coming from the power board. I'm getting 3.5v on the standby pins but 0v on the 12v pins. Have you seen this before? Do you have any suggestions? Thanks

I have a " Hisense tv 40eu300. While I am watching it. The SOUND will go to MUTE for no reason. Then I have to turn the TV off and then back on to get the SOUND back. Can you help me with this problem? Awesome video thanks for sharing it.
my tv has the standby light on and when i turn it on the screen stays black but it's like if there is a light in the background of it but it shows nothing on the tv, the motherboard bight be damaged i think, but im wondering if it's worth it just fixig this tv or just getting a new one all together?
Bad Tcon board. It's a Timing Control board, and when they go bad they can either cause the TV to turn itself off after just a few seconds on, or lines on the screen.
Hello. I have a hard resets, various woodoo combinations. Everything kinda works, but the menu does weird "planned wearout" actions. Sharp 2013 year. 38 inch, have you any advices? I'm a power user of technologies.
Hey there.. wonder if you can point me to the suspect. 55” led LG . 1/2 screen was dk after moving it. So I bought new LED strips. Tested them before assembling worked bright nice. Now after assembling the screen is flickering, I have sound, standby light is on. Backlights stay on but low, the video just has static and flickers on and off. Any ideas?
Hi. In my case, a Seiki flat screen, in powers into a blue or vertical lines screen and audio, but if you let the tv warm up you turn off and on and it's fixed. Will this video on disconecting boards will help or is there another video in your series that for that case? Thanks.
My TV has a problem with the actual on/off button on the side. It is an older Curtis flat screen. I use it as my monitor for my surveillance cameras. Never had a remote. So I have to push the power button on the side every morning. Well the dang thing won’t work 80% of the time. I have to unplug the TV, plug it back in, and over and over, until the button works. Is there a fix? It’s like it is just getting wore out. I thought about just getting a universal remote but if it’s a simple fix then I’d rather do that. THANKS!
i had a similar issues but just replaces few caps on power board. it was the couldnt turn fully on situation but every now and then lol i get parts i need from dump ppl around this time put out good stuff mostly cosmetic damage parts all still good
Nice info, I have the symptoms power LED turn green, TV on a moment, then turn back off to stand by, Red LED, is it backlight issue? I use a bulb for a main power short testing. It was on when Led was green.
Hey I have a 37 inch Sansui TV connected to my computer as a screen. A week ago the screen suddenly made a colorful noise. And the screen went out. There was only the North Standby, but the screen would not turn on. Unfortunately I ordered a new power supply, and I replace it, but it did not help. Then I saw in the video that you were saying it was a logic board. Or T-con. I would be glad to your response Thank you
42 inches Orion plasma TV (42400SI) won't get ON if I do power off / standby / power failure. Only possibility if I use remote for on and off. If the TV won't on i do remove the cable and wait for half an hour and press different types of combination with the both power and standby switch. Sometimes it will on. What will be the problem any solution for this. Looking forward your valuable reply.
Hey Tampatec, I have a Sony KBD-46BX420, mfg & purch in 2011, typical living room use, no harsh environments, only one move in its lifetime. Was watching as normal & suddenly video went black, but the audio remained - did the flashlight test to verify it was a simple loss of backlights. When power cycled, the splashscreen would appear briefly (backlights fire & then shut back off after approx. a second or so). After watching all your videos (thank you), I metered the supply board & verified ALL the voltages were OK, so I suspected the inverter board... I replaced the inverter board & the TV worked perfectly... for about 5 minutes and then the audio & video quickly 'chattered' off/on (for less than a second) & then back to the same exact original problem.... just like before, no pop, no hiss, or otherwise - just loss of the light engine. I suspect that something else (possibly T-con board per other videos) is faulty & causing the inverter to fail?!? My first question would be what would you suspect (I know it's a guess without an actual diagnosis).... Next question - if I order a new T-con board, do you think I will now need another new inverter board? In other words, is there a chance my 2 inverter boards are not permanently damaged & just shutting down, say with a watchdog circuit? I don't want to keep dropping $20 & $30 on boards just to keep blowing them... Any information is greatly appreciated & thanks in advance for your time!
I have a sony xbr65x850e. Turns on for few seconds. Turns off and flashes red 6 times. Theres some brighter spots on the botton middle of tv when on. Also one shadow like spot like goes in and out when on. Any help would be huge. Thanks for you videos they're great.
Just a simple question. Vizio E600i-b3...No picture, no sound, no standby light. Most suggest power supply board. My question is I get all the correct voltages out of pwr supply board except T -Con V which should be 12V. I get correct LED voltages out of main board too. From some vids I've watched there is supposed to be feedback signal from main board to Pwr supply board when power switch is pressed to signal pwr supply to kick in hi voltage. So problem could be main board too. Should I get T Con voltage out of pwr supply regardless of good or bad main board? Cause if I isolate pwr supply from main board I know that shuts off some voltages from pwr supply like the 24 Volts section for LEDs. So it makes me wonder if something similar is going on with the main board not giving feedback properly to the power supply and that's why I got no t-con voltage. I hope this makes sense.
Hi, great video. I have a Technika LED tv. It won't turn on from standby every time. I could be waiting for minutes or even hours for it to come on or it could decide to come on straight away. As the weeks go by it is taking longer and longer for the tv to come on from standby. I've checked the remote with the camera on my phone and that is working. I've tried switching off and unplugging for 30 seconds etc but didn't fix the problem. Can you help please? Thank you.

Thanks for the video, I've got a Medion LCD TV that sometimes turns on but sometimes doesn't. The standby light turns from red to green but the TV sometimes doesn't output a display, any ideas what it could be please?
LG55UF6450 Not powering on. Fuses are good. No obvious burning of board, buldged caps etc. Output/standby voltage on board should be 13.2 volts. Meter reading 55 volts. Your thoughts?
I have a Vizio LED 4K 2019 Model with no standby light. USB Ports work (Led Strip Is On On) but TV does not turn on at all. It was turning on and off by itself so I unplugged it and went to plug in turn back on never turned back on. Assuming either Main Board or Power Board what do you think?
I have a standby light on a Lc-42d64u and will not turn on. I want to repair the issue. Not replace possible motherboard. Any ideas for me to do to test an fix? I haven’t seen a video for this. Thank you! Jason

Hello i have a 55 haeir tv , it is running ok after i replace powersuppy then after couple months the tv sometimes running without the image and after few minute the image appear again.. i am thinking the problem is t-con board? Pls give me advice Thank u and u given alot people help in your video
Thanks for an informative video. I have this LG TV. Recently, it started to misbehave. When it is plugged to power, it can be turned on with the remote (can't be turned on with the power button on the TV). But once it's on, it doesn't respond both to the remote and the power button. What can I do? Thanks.
KDL 32 M3000 Sony, TV off no STBY light, TO with remote or hard button, Back lighting is apparent green power on is lite, So I'm thinking G1M (power board) is good, and maybe BM (Main Logic) is ok, so T-conn is culprit. The boards are available and aren't terribly expensive. I've looked at the Sony parts and diagnostic manual and also tried the Display+5+volume up then on and no menu or anything beyond backlight. Any thoughts to add or should I do the T-Conn and see? Thanks, Great Videos and good content... Robert Phelps
Hi Tampatec, Thanks for all the great info! I had three swollen caps on my power board. I replaced the power board, now I have a standby light but the tv won't turn on. Do u have any suggestions? thanks
Had to do the disconnect several times to get unit to turn on now the red stand by light is on but it will not turn on. is this usually the main board problem?
Watching this video a few times, From my checks I think my TCon board is bad. I have a 24" Element TV, I get a standby light and it also turns blue after pressing the Power button. The screen lights up with the element splash screen then goes black. But I still have the sound of the channel. Looking at your parts recommendations I checked for my board PT and no one has it available!. The board is LS2204037-00-GP(1003). All the capacitors look OK and there are no burnt spots on the board. Any ideas for me before I just scrap the TV? Thanks again for your videos.
advice please. have a samsung, powers on, backlights come on but no picture or sound. checked all voltages coming from psu and fine. would it be the Tcon or video card?
I replaced the entire logic board as the original one stopped working. Put it back, plugged all the connections, but although the bottom light on the unit is on (blinking red), it does not turns when using the remote control. The TV does not produce any sound or image. Any suggestions? It is a Hisense Model 50RGE1

Hi Tampa Tech, I would like to know, when it comes to replacing a board do I only used the board number stamped on it or do I have to use the barcode tapes which have a number as well. Thank you.
I have a 4k element 65” tv that has an FRC board and the issue is the the tv has standby light red but the tv won’t turn on I replaced the power supply that had bulging caps and just tried two different main boards did not fix the issue so I have no idea what is wrong with it the boards for this tv are supremely rare to find and I’m really trying to fix it it’s my first tv I’ve ever invested in from brands mart in 2015 any advice would be great
Hi tampatec i wish I can talk to you on phone.i have a lg 42 pc3d plasma. It took a fall backward while sitting on the floor and after that it won’t turn on. The standby light is blinking green. I tried unplugging and holding the power button and some times the stand by light will turn red and stop blinking but once I try turning it on it goes back to blinking green.there is no back light either.thanks in advance I willl like to come to Tampa and meet you, I live I Deltona Florida.
Hi Sam, I don't have a TV shop and only fix tvs as a hobby. Your TV is a Plasma TV and doesn't have a backlight like LCD and LED tvs do. if your tv fell then it most likely has a cracked plasma tv panel but to be sure you have to disassemble the tv to check for cracks. you can sell your TV broken or sell the TV boards for $55 each on ebay. hope that helps.
I have a sharp lc-70le660u one day the screen blinked and went black it would come back on randomly now power light cones on screen flickers and goes black wont factory reset with the buttons what do you recommend
HI Tampatec, I have standby and i get sound the screen itself wont power on but i am getting 19v on the 12 v rail could this be over powering on the logic board
My 55 inch westinghouse tv model number wd55ub4530 has red light but wont turn on. From what you described, it sounds like the main logic board needs to be replaced. How do I identify this board once I open the tv?
Hey TampaTec I have an LG TV (55UH6030UC). It will not turn on or off with the remote but the TV power button works just fine. I was told that the Main Board is the problem. My TV uses LG 55UH6030-UC AUSWLJR main board but I see LG 55UH6030-UC BUSWLJR. What is the difference and can I use a BUSWLJR board on a TV that has an AUSWLJR board?
hello from the uk great video's i am trying to find some voltage settings for my sony tv so i can troubleshoot a problem i have with it! but it seems like a closed shop 000 can you give me any address were possibly i could get a diagram etc i plug the power in & all i get is a standby light for 3-4seconds then nothing else the tv is only 3 years old in my estimation the quality of sony tv's has declined having there products over 50 years any advice would be much appreciated thanks from a 80+year old man
Your videos are always helpful. I enjoy every single one. thank you very much. Could you put a link to the schematic that you made on 1:40 about "Power Supply turn on Sequence" ? it'd be very appreciated.
been having trouble with hisense 50 inch for awhile. at first and for about 3 months now, ive been unplugging the power cord for 60 seconds, and that has worked till this morning. now reseting by doing that wont do the trick. would a power cord itself possibly fix my problem, or have you ever seen that? the tv is out of warranty, i have a multi meter and am willing to try testing it like the other video you have shows for 5 volts.

When i plug the tv. The red led light is steady on but the tv wouldn't turn on?? What was the problem sir.
He just did explain, main or power board or both.
Thank you tampatec for sharing this beautiful video of how to fix power board keep sharing God bless...
I got a TV where one if the HDMI ports only the sound works but the video is dead/black. Any good advice?
Tampatec, thanks very much for your videos, they're terrific. I have a problem with a Sony Bravia (KDL-46HW800). It turns on, is fully functional and has a perfect picture for 5-10 minutes. After that time, it abruptly shuts down. The red light blinks 6 times. I've replace the power board but that didn't repair the issue. Any advice would be great. Thanks!
Kdl models are known for bad tcon boards. I made Sony TV repair videos, see my TV repair playlist or Sony playlist.👍
Thanks so much, I'll check it out.
My TV doesn't turn on. I get the orange led and nothing I press works. How can I fix it
when I click on, it turns green for a sec and then goes off
Ebay is the most reliable parts finder,... every time I go to ShopJimmy, what I need is out of stock!
Hi by the way i like the videos you post up on Tv's and been learning how to fix an hdtv. My question is that I'm having trouble with an LG 55lk520 (55inch tv) and had the power supply replaced, main board, backlight inverters. Power supply might have pins messed up connected to the main board and was wondering if thats the problem from not powering up?
THANK YOU FOR YOUR HELP BECAUSE I HAVE A KARAOEKE WITH MONITOR THAT IS NOT CONSISTANT,SO IM GOING TO REMOVE THE TCON CIRCUIT BOARD TO SEE IF MY IPOD WILL PLAY A MOVE FROM THE DOCK.
Hi Tampatec and thanks for the vids. I have a Sony KD-65X9000B that now blinks 4 times with no other response. I've pulled it apart and have measured the voltage coming from the power board. I'm getting 3.5v on the standby pins but 0v on the 12v pins. Have you seen this before? Do you have any suggestions? Thanks
In my day job I've gotten a Samsung UE32F5000AX out of a skip/dumpster. Hoping this video helps get it working.

Can I use the normal LED's instead of the SMD's in a TV backlight? when they burn out?
Great stuff! I have a Sharp Aquous LC-40D68UT. When I tried the reset (Vol- & Input, 5 secs) I was able to get the TV to reset, but the screen goes black again after a second or two. Help?
I have a " Hisense tv 40eu300. While I am watching it. The SOUND will go to MUTE for no reason. Then I have to turn the TV off and then back on to get the SOUND back. Can you help me with this problem? Awesome video thanks for sharing it.
my tv has the standby light on and when i turn it on the screen stays black but it's like if there is a light in the background of it but it shows nothing on the tv, the motherboard bight be damaged i think, but im wondering if it's worth it just fixig this tv or just getting a new one all together?
Having the same problem
Same aye got the same problem
Hi I have been watching your videos and I was trying to fix my tv which has only lines on the screen
Bad Tcon board. It's a Timing Control board, and when they go bad they can either cause the TV to turn itself off after just a few seconds on, or lines on the screen.
Hello. I have a hard resets, various woodoo combinations. Everything kinda works, but the menu does weird "planned wearout" actions. Sharp 2013 year. 38 inch, have you any advices? I'm a power user of technologies.
Big thumbs up 👍🏼. Love me some Tampatec! You always have such great content, once again these little tips are so great to have. Thank you!
Hey there.. wonder if you can point me to the suspect.
55” led LG . 1/2 screen was dk after moving it. So I bought new LED strips. Tested them before assembling worked bright nice. Now after assembling the screen is flickering, I have sound, standby light is on. Backlights stay on but low, the video just has static and flickers on and off. Any ideas?
Hi. In my case, a Seiki flat screen, in powers into a blue or vertical lines screen and audio, but if you let the tv warm up you turn off and on and it's fixed. Will this video on disconecting boards will help or is there another video in your series that for that case? Thanks.
My TV has a problem with the actual on/off button on the side. It is an older Curtis flat screen. I use it as my monitor for my surveillance cameras. Never had a remote. So I have to push the power button on the side every morning. Well the dang thing won’t work 80% of the time. I have to unplug the TV, plug it back in, and over and over, until the button works. Is there a fix?
It’s like it is just getting wore out. I thought about just getting a universal remote but if it’s a simple fix then I’d rather do that. THANKS!
Hi. I have a Sony 32 inch tv it won’t show no picture wen I cut it on but the green light be on wit no pictures showing black
i had a similar issues but just replaces few caps on power board. it was the couldnt turn fully on situation but every now and then lol i get parts i need from dump ppl around this time put out good stuff mostly cosmetic damage parts all still good
Thank you so much it really worked bro 🙂.
Nice info, I have the symptoms power LED turn green, TV on a moment, then turn back off to stand by, Red LED, is it backlight issue? I use a bulb for a main power short testing. It was on when Led was green.
Hi Tampatec I have got Telefunken model TLCD 40 INCH FHDA I switches it on some few seconds like 3 seconds turns off
Hey
I have a 37 inch Sansui TV connected to my computer as a screen.
A week ago the screen suddenly made a colorful noise. And the screen went out.
There was only the North Standby, but the screen would not turn on.
Unfortunately I ordered a new power supply, and I replace it, but it did not help.
Then I saw in the video that you were saying it was a logic board.
Or T-con.
I would be glad to your response
Thank you
42 inches Orion plasma TV (42400SI) won't get ON if I do power off / standby / power failure.
Only possibility if I use remote for on and off.
If the TV won't on i do remove the cable and wait for half an hour and press different types of combination with the both power and standby switch. Sometimes it will on.
What will be the problem any solution for this.
Looking forward your valuable reply.
Life saver ❣️ just got mine fixed. Plug out then plug in
Hey Tampatec, I have a Sony KBD-46BX420, mfg & purch in 2011, typical living room use, no harsh environments, only one move in its lifetime. Was watching as normal & suddenly video went black, but the audio remained - did the flashlight test to verify it was a simple loss of backlights. When power cycled, the splashscreen would appear briefly (backlights fire & then shut back off after approx. a second or so). After watching all your videos (thank you), I metered the supply board & verified ALL the voltages were OK, so I suspected the inverter board... I replaced the inverter board & the TV worked perfectly... for about 5 minutes and then the audio & video quickly 'chattered' off/on (for less than a second) & then back to the same exact original problem.... just like before, no pop, no hiss, or otherwise - just loss of the light engine. I suspect that something else (possibly T-con board per other videos) is faulty & causing the inverter to fail?!? My first question would be what would you suspect (I know it's a guess without an actual diagnosis).... Next question - if I order a new T-con board, do you think I will now need another new inverter board? In other words, is there a chance my 2 inverter boards are not permanently damaged & just shutting down, say with a watchdog circuit? I don't want to keep dropping $20 & $30 on boards just to keep blowing them... Any information is greatly appreciated & thanks in advance for your time!
I have a sony xbr65x850e. Turns on for few seconds. Turns off and flashes red 6 times. Theres some brighter spots on the botton middle of tv when on. Also one shadow like spot like goes in and out when on. Any help would be huge. Thanks for you videos they're great.
Just a simple question. Vizio E600i-b3...No picture, no sound, no standby light. Most suggest power supply board. My question is I get all the correct voltages out of pwr supply board except T -Con V which should be 12V. I get correct LED voltages out of main board too. From some vids I've watched there is supposed to be feedback signal from main board to Pwr supply board when power switch is pressed to signal pwr supply to kick in hi voltage. So problem could be main board too.
Should I get T Con voltage out of pwr supply regardless of good or bad main board? Cause if I isolate pwr supply from main board I know that shuts off some voltages from pwr supply like the 24 Volts section for LEDs. So it makes me wonder if something similar is going on with the main board not giving feedback properly to the power supply and that's why I got no t-con voltage. I hope this makes sense.
Hi, great video. I have a Technika LED tv. It won't turn on from standby every time. I could be waiting for minutes or even hours for it to come on or it could decide to come on straight away. As the weeks go by it is taking longer and longer for the tv to come on from standby. I've checked the remote with the camera on my phone and that is working. I've tried switching off and unplugging for 30 seconds etc but didn't fix the problem. Can you help please? Thank you.
Thankyou! Your video was so helpful!
Just subscribed. getting 60 volts from the 80v pins and 9.2v on the 13.2 boards. Bad power supply? Standby light will blink 3 times when button is pressed. Thanks...
Thanks for the video, I've got a Medion LCD TV that sometimes turns on but sometimes doesn't. The standby light turns from red to green but the TV sometimes doesn't output a display, any ideas what it could be please?
Gremlins
LG55UF6450 Not powering on. Fuses are good. No obvious burning of board, buldged caps etc. Output/standby voltage on board should be 13.2 volts. Meter reading 55 volts. Your thoughts?
I have a Vizio LED 4K 2019 Model with no standby light. USB Ports work (Led Strip Is On On) but TV does not turn on at all. It was turning on and off by itself so I unplugged it and went to plug in turn back on never turned back on. Assuming either Main Board or Power Board what do you think?
I have a standby light on a Lc-42d64u and will not turn on. I want to repair the issue. Not replace possible motherboard. Any ideas for me to do to test an fix? I haven’t seen a video for this. Thank you! Jason
t must make you so much happier with 8..sorry 9 thumbs up and not a hint of a fix yet?! :)

Hello i have a 55 haeir tv , it is running ok after i replace powersuppy then after couple months the tv sometimes running without the image and after few minute the image appear again.. i am thinking the problem is t-con board? Pls give me advice Thank u and u given alot people help in your video
Thanks for an informative video.
I have this LG TV. Recently, it started to misbehave. When it is plugged to power, it can be turned on with the remote (can't be turned on with the power button on the TV). But once it's on, it doesn't respond both to the remote and the power button. What can I do? Thanks.
KDL 32 M3000 Sony, TV off no STBY light, TO with remote or hard button, Back lighting is apparent green power on is lite, So I'm thinking G1M (power board) is good, and maybe BM (Main Logic) is ok, so T-conn is culprit. The boards are available and aren't terribly expensive. I've looked at the Sony parts and diagnostic manual and also tried the Display+5+volume up then on and no menu or anything beyond backlight. Any thoughts to add or should I do the T-Conn and see?
Thanks, Great Videos and good content...

Help
Watching this video a few times, From my checks I think my TCon board is bad. I have a 24" Element TV, I get a standby light and it also turns blue after pressing the Power button. The screen lights up with the element splash screen then goes black. But I still have the sound of the channel. Looking at your parts recommendations I checked for my board PT and no one has it available!. The board is LS2204037-00-GP(1003). All the capacitors look OK and there are no burnt spots on the board. Any ideas for me before I just scrap the TV? Thanks again for your videos.
advice please. have a samsung, powers on, backlights come on but no picture or sound. checked all voltages coming from psu and fine. would it be the Tcon or video card?
Tcon board or main board. Sometimes tcon board is built into the main board. Get TV boards at shopjimmy.com and Electropartsonline.com
@@TampaTec Tcon board is seperate. should i replace Tcon first alone since its cheap? thanks man!
I have the same problem on my Samsung un55D6000sfza tv .. did you find the fix yet?
I replaced the entire logic board as the original one stopped working. Put it back, plugged all the connections, but although the bottom light on the unit is on (blinking red), it does not turns when using the remote control.
The TV does not produce any sound or image. Any suggestions? It is a Hisense Model 50RGE1

Hello. Please help how I can repair my vsus board for Panasonic Viera P50X20 plasma tv.
Hi Tampa Tech, I would like to know, when it comes to replacing a board do I only used the board number stamped on it or do I have to use the barcode tapes which have a number as well. Thank you.
I have a 4k element 65” tv that has an FRC board and the issue is the the tv has standby light red but the tv won’t turn on I replaced the power supply that had bulging caps and just tried two different main boards did not fix the issue so I have no idea what is wrong with it the boards for this tv are supremely rare to find and I’m really trying to fix it it’s my first tv I’ve ever invested in from brands mart in 2015 any advice would be great
Hi tampatec i wish I can talk to you on phone.i have a lg 42 pc3d plasma. It took a fall backward while sitting on the floor and after that it won’t turn on. The standby light is blinking green. I tried unplugging and holding the power button and some times the stand by light will turn red and stop blinking but once I try turning it on it goes back to blinking green.there is no back light either.thanks in advance I willl like to come to Tampa and meet you, I live I Deltona Florida.
Hi Sam, I don't have a TV shop and only fix tvs as a hobby. Your TV is a Plasma TV and doesn't have a backlight like LCD and LED tvs do. if your tv fell then it most likely has a cracked plasma tv panel but to be sure you have to disassemble the tv to check for cracks. you can sell your TV broken or sell the TV boards for $55 each on ebay. hope that helps.
I have a sharp lc-70le660u one day the screen blinked and went black it would come back on randomly now power light cones on screen flickers and goes black wont factory reset with the buttons what do you recommend
HI Tampatec, I have standby and i get sound the screen itself wont power on but i am getting 19v on the 12 v rail could this be over powering on the logic board
My 55 inch westinghouse tv model number wd55ub4530 has red light but wont turn on. From what you described, it sounds like the main logic board needs to be replaced. How do I identify this board once I open the tv?
Hey TampaTec I have an LG TV (55UH6030UC). It will not turn on or off with the remote but the TV power button works just fine. I was told that the Main Board is the problem. My TV uses LG 55UH6030-UC AUSWLJR main board but I see LG 55UH6030-UC BUSWLJR. What is the difference and can I use a BUSWLJR board on a TV that has an AUSWLJR board?
hello from the uk great video's i am trying to find some voltage settings for my sony tv so i can troubleshoot a problem i have with it! but it seems like a closed shop 000 can you give me any address were possibly i could get a diagram etc i plug the power in & all i get is a standby light for 3-4seconds then nothing else the tv is only 3 years old in my estimation the quality of sony tv's has declined having there products over 50 years any advice would be much appreciated thanks from a 80+year old man
Thank you so much I was struggling Soo bad thanks
Your videos are always helpful. I enjoy every single one. thank you very much.
Could you put a link to the schematic that you made on 1:40 about "Power Supply turn on Sequence" ? it'd be very appreciated.
been having trouble with hisense 50 inch for awhile. at first and for about 3 months now, ive been unplugging the power cord for 60 seconds, and that has worked till this morning. now reseting by doing that wont do the trick. would a power cord itself possibly fix my problem, or have you ever seen that? the tv is out of warranty, i have a multi meter and am willing to try testing it like the other video you have shows for 5 volts.
Hey can you help me with the led strips model number that go in A Aquos 60LE550U
