Extremely impressive demonstration. Actually even though you had it all worked out, it was somewhat complex and probably expensive. I don't know if I hit the right button for other similar demonstrations but I would like to see more similar videos from you.
I've been watching this guy for years, he one of the best nerver stop learning.
Thank you. A great job. Nice teaching, and that is very useful for beginners like me. Greatly appreciate this teaching.
Thank you for putting this video together, it was a huge help! I have a Vizio E601i-A3E that went black with sound. I could see the TV with the flashlight test and went through this entire video, pausing to test along the way. When I would turn on the TV, my backlight would stay on for a few seconds and then turn off so I used your guidance on the voltage test of the backlight circuit to help me diagnose that it could be a power board problem. I kept testing everything including the T-Con board but the power board seemed to be the part that needed replaced. I bought the part from Shop Jimmy as you suggested and installed it and the TV works great. Thank you again and I know where I'm going next time I have a TV issue!

Excellent demo thank you! Can't wait to dig into my new (old) tv and see what's up
Very appreciated your videos. It helped me to repair a Samsung 55 out in the nowhere. Just ordered the spare parts and it got up and running.
Hi my LG TV kept switching to stand by 3 yrs ago.
I fixed it, quiet easily: I threw the f at the wall; It's been great ever since!
Like your vids, informative and helpful.

This is an incredible video, thank you so much for your time and teaching! The in-depth step-by-step explanation of your whole process is invaluable!
Great video as usual
Thanks
Just fixed our Vizio TV with your help, we replaced the driver board and it is now working.The TV had the black screen with audio but no picture unless you used a flash light on the screen then you could see the screen was on. The part board cost less than $12 dollars.
I fixed a similar model vizio and the issue was the LVDS cable. I almost didn't catch it and thought the LCD panel was bad, but glad it was the ribbon cables going into the t-con board.
Took a drink every time you said zero. I have zero alcohol now.
Very helpfull videos, very well explained, thank you
You are the best man 🙄👍.
You are definitely the man. I subbed twice🙄🙄🙄
Very and highly informative. Thank you recommend visiting to all
thank so much it really helps me... love from philippines
Thoroughly explained how to repair my vizio tv to eliminate my problem. I have not tried it yet, but I thought you deserved a positive comment. I'll keep you posted. Thank you for taking the time to help us all out and save us hundreds of $$.
Thanks for the videos my 55"vizio popped when my wife turned it off and after a few weeks of your help I've located the blown parts on my power board.
Still don't know what the name of them but testing with a meter after your video I've located the shorted parts yes not just one
One part sucked the solder up through the board and another blew its top off leaving no info so I hope my local electronic shop can help me out
Hey Your Good, I really appreciate your explanation of trouble shooting. thank you
another great video. Thanks a lot buddy
This is awesome man! Thanks for sharing
Excellent! Thank you.
You are the best tech bro
thankfully Sir and God bless
Loved this Thanks
Thanks for sharing great video
Great work thank you
Thanks you!
Nice info,
Thank you.
Yes! it was ! but darn I have no tools! I'll have to get a repair guy. but this will be a help on knowing price wise and all....
I can't see Backlights TV still intact not opened but the Vizio front light is on.
I really enjoy your videos. I used to work on some older TV's and VCR's. Good to see how to troubleshoot the newer ones. Keep it up.
Thanks for this video
Great and helpful video! Quick question, if there is no apparent backlight in step 1, what's the next step? LED Controller board replacement or continue troubleshooting? Main board gets red LED lit when plugged in. Then when power button is pressed, that light turns pink and the power indicator light on the front of the TV comes on solid, then blinks for 34 times, then fades out. After this, the pink LED turns back red.
Awesome advice, really helpful
Andy Truth Finder thanks
thank you for all the info..i share it to my student..and the tips and lcd led repair..helps a lot of student..god bless and ..god job...:)
thanks
@@TampaTec I have the same exact issue as you do i have 12 volts at the main board cable going out to the T-Con board (*one closest to the top of the TV Screen*) But the other one below it, No Dice! (*one closest to the bottom of TV*) How can Repair the main board? I have plenty of extra parts from other sets, as i am venturing in this for a hobby. Just need to know what to test from here.
Good and informative video..
Good work brother Thank.u
I say thank you from🇹🇿🇹🇿🇹🇿🇹🇿🇹🇿🇹🇿🇹🇿🇹🇿
thank buddy love your work
I got panasonic tv 4k is on with panasonic writing only
Excellent video! I am having almost the exact same issues with my Panasonic TC-39AS530U. TV turns on, screen flickers 3 times (I can see the LED lights flickering in the back), then I get a blank screen with 1 LED flicker (error code 1 I assume) then just a slowly blinking red LED. There is no sound and I can't turn it off with the remote. I have to press and hold the power button on the side of the unit or unplug it to turn it off. I have tested my power supply board. ALL 3 test points (standby, LED driver, and main board) maintain voltage when it goes from power on to blinking light. However, the pins on the connector for the main board and driver board go from 16V and 24V respectively down to 0 when the light starts to blink.
There are 3 test points on the main board, 5.3V, 12V, and 15V. The 5.3V (standby) maintains voltage when it goes from power on to blinking light, the other two do not, they go to 0. Would that, along with voltages being maintained on the power supply board, indicate that this main board is bad? I really hope that is the case as I do not want to get into replacing LED strips. Thanks and keep up the great work! P.S. I have put in new power supply and T-con boards and the problem continues.
Like your videos, very informative. I have Vizio 70inch LED TV. Model M70-C3. Black screen, no backlight. The power button lights up and the optical audio port lights up. I removed the back panel and checked the voltages on the Power Supply board.connector to Main Board, standby voltages for AC det =3.96, PS on =5.13 and AU =12.. Pins 8&9 VS =12v. Pins 13&14 T-con =12v, however pin 15 T-con on =0v. Also T-con connector pins 1,2,3,4 measured 0v instead 12v. Checked output voltages on LED Driver connector. Pins 3-8 measured 34v instead of 24v..Pin 13, vsense =2.6v. To summarize, zero voltage output to T-con board and higher voltage 34v instead of 24v going to LED driver board. Can you advise me on which board I should replace. My initial thought was the Power Supply board, however I guess it could be the Main Logic board not setting T-con on. Appreciate your expert advice.
sorry for late reply, I get many questions. If you turn off the room lights and See a Backlight Glow and no picture then it can be the T-con board or main board. Like u said if you don't see backlight glow it can be bad LED strips (very common). get TV parts from shopjimmy.com
thanks for being a member!
Very informational thurogh and helpfull. Only question I have is my TV shows all proper voltage except power to back lights. How do I troubleshoot that part of the power board.
I had like the same poblem with my sharp 47 inch i got a teacon board for £12.00 wich is roghly $7.00 from ebay and i diden!t use the meter just looked at it to know what was wrong.Still .Very good video and informative from you Sir.
Keep them alive LOL
Ohh so thats how you repair that thats awsome thank you man! :)

You have very informant videos I have a hisense HDTV looking for a video on humming sound need your help thanks
Thanks for great advice. I have a Sharp Aquos 70 LCD similar to one you’ve fixed before. Not sure what happened to it, but the screen started looking like a work of art. Based on additional videos and talking to some people, they recommended changing the tcon board - which I just did last might buuuut nothing happened, now it’s just a blue screen. The backlights are on, but there’s still no picture or sound. What do you recommend as the next course of action? I would love the fix it, but don’t want to end up investing more money into it and it’s not repairable.
Thx for you how to videos. Fixed my pos Vizio with a used $15 t-con board from eBay. Now I’m returning my new 85” Samsung 😢
I can barely see the picture in our Vizio and I was wondering if you could help me get it brighter? I appreciate your help thanks so much Tampatech you’re awesome sharing your wonderful skill with us ... ps we have sound and dark screen
I really appreciate all of the work you have presented. I have watched probably 8 or 9 of your videos and read some of your blog. I am trying to debug my mother's Westinghouse LTV-32W6. It has power, sound (at least a squealing sound), and backlights, but no video on screen. Her tv's t-con board is not accessible without moving the main board and power board, so I can't test it the way you indicate plugged in..
I should be able to test the power out of the power board to the t-con board, is that enough to say it is the t-con board that is bad? How do I differentiate between t-con and inverter board?

Great video, but I have a question. Are you using the tile adhesive in the shot for repair of electronics?
Superb master ..
Hi Tampatec, massive fan of your videos. Think I've probably watched every single tv one. Just a request really... It'd be really cool if you did a break down of the power supply board, like talk about the process of converting from AC to DC, the smoothing process etc. Can't find a single one on RUclips. Thanks dude.
Hey Loz, 4 years late but did find any on youtube? Just wondering. Cheers man :)
@@humblelittlekitchen4983 I never did find any dude 🥺
@@lozmarks Ah that's a shame. If I find any, I'll pass it on buddy. 👍
You have good videos. I'm trying to trouble shoot my tv and at this point I believe the t con is bad. Haven't checked the back light yet although I do see a blueish glow on some of the inputs. And some sound here and there but then does out. Any ideas? Thanks again for the videos
Good job
Tampactec thanks for your great videos they are very helpful. I have a Panasonic TX 55 Cx400B tv it has sound but the only picture is on the very lower bottom of the screen eg where notifications appear such as breakingnews the rest top of the screen is white. I got a use TCon board online but no deference. I removed and pushed the cable from power to TCon and from TCon to display buffer board no change I will greatly appreciate some advice David
Thanks for awesome videos ! I would like now where can I get a Fluke 12 multitester like you ! thanks Tampa Tec
I bought a 39" Vizio D series, 13 months (yep) ago from Walmart. It worked good for about 10 months until it would freeze pic or go blank. Unpluging it and plugging it back in would correct the problem But it went from doing it twice a week to 5 times a day. It finally started going off and on displaying the "V" screen and then the back screen. The only way you could get it off was to unplug it. The other "odity" was when I went to pop the cover off I found A "Amazon" Firestick plugged into it. Obviously the TV had been sold and returned and resold to me but now stuck with it. Help,!
Thanks mate it works.. nice jop 😊
wow you are the Flash
Great video! I have a 4x5 area upper left that's like a brown splotch. It's a Vizio M65 C1. Have you seen this issue?
good job buddy................
Thanks for this deep troubleshooting, I have 75' Vizio flat screen with three busted capacitor in the power board, I replaced the 3 capacitor but the TV will still not come on though the capacitors rating was 68uf 450 but I was able to get 47uf 450 to replace them but still not working no single light anywhere
You need to get same value 68uf cap and might be more bad capacitors nearby.
thanks, Tampa Tec
Dude u rock thanks
That black n decker drill is the best drill in the world for its size, i use the back of it as a hammer even
Hey tampatec great vid as usual. So I was fixing my TV Vizio 55" E series, and I had gotten the lights to come on and I could get pic, but some of the LEDs needed to be replaced. Then my daughter ( 1.5) climbed onto my table where the TV was and was sitting of my freaking TV. Now I can't get lights on and when I do the flashlight test I only see the right half of the screen. One of the Hard wired ribbon cables gets a little hot. Is my TV toast?
GREAT INFO BROTHER
Thank you for the upload.
hi i like your video i have a sylvania LC320SL1 i turn it on but it goes out. i do have a standby lite on. i open it up and found no damage. so i check for 3 volt dc and i have for about three second with power on. i disconnect the power inverter and i have the 3 volt and a green lite. i think the power inverter is bad. i also check on some diode and found two bad one the the power inverter. help
great videos, I have a LG smart TV. it is going on I can see even without flashlight but it looks like the brightness is in very low (actually it is not). I cannot see any bad part, also power in backlight is 145volt. I actually did not do the test with backlight and light off. Any idea ...? thanks
Tampatec you mentioned replacing a vizio screen panel display. Just wondering where can I find sharp aquos 60" used screen.
exelent video
Hi and thanks for the tutorial, but can you tell me what led I can use to get my bauhn 40 inch led smart TV working. The manufacturer said they don't have any more stock available for this TV. Can you help
hey tampatec, i have a westinghouse 40" that will stay on for about an hour or so with great sound and picture. after this hour or so the entire screen becomes blank and green and then powers off or at least the display shuts down. i have been reading its the graphic board and possibly from overheating. would you recomend me just ordering a new graphics board?
thank you nice video ;)
Hey I don't know if you have any quick fix trouble shooting for the 55 ' insignia NL-55 MODEL FLICKERING SCREEN ?
I have the same exact tv with sound & no picture, do I think replace the t-con board or the main board?
Cheers!
I want to make a constructive criticism so that it helps us and you also help him in the visits. creating subtitles in Spanish would be great for people who don't know English. Right now this is translated by an app because I do not speak English and they recommended your channel. Thank you very much for your work.
Hey man, I'm a newbie. why does this one component run on 160 Volts if the US uses 110 and most other countries 230? what's the advantage for the manufacturer converting currencies up or down for a single component? :/
love your channel. keep doing what you're doing ;)
What??
I have a sharp lc-65P6000 about a year old, got water on the back side. I now ave a 3" vertical strip just left of center that is a lighter shade than the rest of the screen. After a lot of investigating and thanks to your videos, I guessing it might be a connection at the T-con board. Am wondering your thoughts. Thanks
In ordering the tcon board, does it matter if its a ZH vs ZM at the end of the part #?
Hey Tampatec do you know what causes a screen shift like an image that is about 1/8” covering. Gives it kinda a 3D look?
Great video! My sharp tv looks similar. LC70LE550u when the TV is OFF I get two slow blinks continually. When I turn ON the TV the blinking stops the back light comes ON and the screen lights up white but no picture, only sound. I cannot find any error code that fits the two slow blinks except for power PCB. But the voltages on the power board reads good. Any suggestions/help, would be appreciated.
Enjoyed this video for the test points. Checked the voltage at the tcon connectors at the main board but only have 12v on one connector. Tv has sound, channels and backlight but no picture. Tried replacing tcon board but no difference. Do I replace the main board?
+steve Fayet +Tampatec I have the same exact issue as you do i have 12 volts at the main board cable going out to the T-Con board (one closest to the top of the TV Screen) But the other one below it, No Dice! (one closest to the bottom of TV) How can Repair the main board? I have plenty of extra parts from other sets, as i am venturing in this for a hobby. Just need to know what to test from here.
Nicse teaching
Hi! Thanks for video. Can you help me please, have a sharp lc-65le643u and show green line on all image
hi tampatec. u have an awesome video on tv repair. I have a panasonic 55 " tv that first lost its picture and i cleaned the tv a couple of times and the picture returned but now the picture went out and i don't understand how to fix it. I've seen some of your video's on other tv's but they look different than mine. Plz help because I have no tv now. thanks. Jack
so nice and slow Was great video
I want the fluke 12. Had one. miss it.
I'm pretty sure mine is the main board that's bad. I've measured 12 volts on the 51 pin connector, but not on the 41 pin connector. Some of the pins of my 41 pin connector only have 1.3 volts. All power measures okay from my power supply. My back light powers up okay too. I'll update this if I purchase a new board with success.
Tampatec was wondering, if my IR sensor board isnt working properly, would I need to replace the cable too??
Hey so I've been trouble shooting my TV issues for a few weeks now. I bought a new T-con board, but still no picture. There's no voltage drop across the part you identified that has a burn hole, but I do get some results on a diode check. There's 12VDC coming from the main board, but nothing going out to the LCD screen. Are there some upstream components I can check to see where I'm shorting out?
hey tampatec my LCD vizio tv comes on after ten min it cuts off I put a new power board in it an the same tihing happens what dou think
So did replacing those two parts actually fix this TV? I have the same problem....
Nice videos! I have a Vizio E550i-B2 With backlight, no tv image but have a blue/white/gray light on screen and with audio. I purchased a combo panel in shopjimmy but nothing happened, i send it back boards. But i don't know if the combo board are damage too. What you recommend? Try again with new boards or put the tv on the trash? Thanks
What should I look for on a LG plasma TV no standby power on power supply board all fuses are good
Working on this same tv, bought it for cheap because it wasn't working... took it home, plugged it in and to my surprise it turned on! However, 5 minutes later the c2 cap blew up in my face lol. I switched out that cap and it tuned on, but again, the cap i just put in started venting after 5 min...
I'm wondering if it was just a crappy cap i put in, or if maybe something else is going on? I'm afraid to try again without being sure because the smell of the venting caps is ruthless...
Any ideas would be greatly appreciated
Tampatec, HELP! I have the exact model in this video. I have no backlight and cannot see any image with flashlight. It also makes a pop noise from the speakers when plugging the cord into the outlet or when turning on with power button. I hear the "logic" board start up and have the red light for the audio and white light on the front. I measure correct voltages at the connector on the power supply for the logic board. I do not have voltages at the connector for the backlight on any of the pins.
Is there a way to send you pictures. I have a 32 inch LCD samsung and I beleive it has a bad Backlight panel.
I've a 23 year old Toshiba TP48E50 projection tv that lost its picture but has sound. All fuses were checked and nothing on the boards appears burned. Any ideas on this? Thanks for your help and all your videos!
Hi there I have Vizio M3D550KDE when I put in store mode or I'm setting up tv I can see the whole screen in color how ever when I try to put in avs cable to game or DVD player it shows black and white color as well when I hook it up to HDMI I don't think it's the led or lcd screen wht could be
