How to Troubleshoot LED LCD TV No Picture pt2

[@TampaTec]

Damn a dislike in 30 seconds after uploading the video, lol. they didn't even finish watching the video, good thing i get credit for views not by likes and dislikes. guys my videos can't get better unless you "tell me" what you disliked. is it too long or too confusing or do you just want the solution and no tutorial or you hate my voice or my Face lol, what???? For those who liked thanks but tell me what you liked too so i can keep it up 8^) ♥︎♥︎♥︎ love for my subscribers and even the haters ♥︎♥︎♥︎ thx 4 watching

Somebody always going to bitch. Keep up the good work

[@pbarnak]

I love your videos. You have to watch them all the way through and sometimes I have to watch them more than 1 time to make sure I understand all of the steps. Keep up the good work. You are very thorough. I have a little more confidence to check the old T-con board first to see if I am getting any voltage through it. Only thing that is confusing me is the white circle on the bottom left of my TV screen. Is that caused by a bad T-con board or a LED driver board? I am hoping it is just the T-con board.

[@pbarnak]

Do you have a PayPal account where someone could donate money for your videos if they want to? They are so good that if I saved money because of them I would like to reward you for your time.

[@TampaTec]

+pbarnak white circle ? unplug all the video cables from the lcd Tv and the tcon board, if it's still there it can be from backlight just lower backlight settings. burn-in happens on plasma TV.

[@TampaTec]

+pbarnak thanks however I don't accept donations because there are more needy people than me. I'm not rich but KZbin helps me greatly. what helps more is subs, likes, sharing the videos helps this channel survive and grow. this generation is a throw it away society, we need to change that. that's why I love to hear posts when someone fixes their TV.

[@bigdog8882]

From my experience, the 60 inch problem is almost always the T-Con board. On the 70 inch its almost always the panel. Just unplug the connectors from the t-con board one at a time. If you get half picture then you already know you got a bad panel. Time Saver! Good Video!!! Shows the Shii.. we go through and how we get better.

[@CloudsVex]

Does this need to be done with the new T-con? I have this T.V. and I unplugged each side by it's self and nothing changed. I assume It has to be done with a new t-con board? Has black screen with backlights lit / no video

[@prtbone78]

I put new tcon board new led driver board and new main board. Same issue. Tv turns on and displays image but after about 10 mins. I guess after tv and components warm up or heat up tv stops displaying the image. Still hear sound just display is out

[@allen5976]

Your honesty in showing us that not everything works out working on these modern tvs is testament to you. I recently took on a free Panasonic tx 48cx400b that had no backlights, I bought a new power supply as the other was shot and the backlights would only flash for an instant. The screen was veri by the flashlight test. I stripped the panel and continued to test the leds but made the huge mistake of injecting dc voltage into the strips not knowing that they are controlled by current, not voltage and burnt out all the leds. I've spent another €40 on new backlights even though I have almost the price of a new tv spent but I hate putting any in the scrapheap. New panel costs will have to be reduced to prevent this massive unnecessary waste worldwide. Thanks for the knowledge 👍

[@lucasogden8619]

Yes it helped a lot, thanks for not just showing what to do but also what not to do, which is just as critical. Your honesty in reviewing your mistakes along with required repairs speaks volumes about your integrity and true desire to teach others to become competent repair specialist such as yourself. Look forward to receiving some of the tools you use and have recommended as well as your supply stores.

[@ismetgracanin266]

Thank you so much for this video . It is so helpful so people will stop replacing t-con twice! Many tv repair men won't show their mistakes. Thank you for your honesty!

[@howelltonmusic]

These videos are very helpful for someone trying to fix their own TV. Thanks!

Bro its good that you show us those knids of failures so that we know what to do facing the same situation.

[@cherokeethunder6000]

[@planetmadness5202]

Reset the ribbon to the buffer board & inspect ribbon with microscope. They sometimes will have tiny burn holes where the connector contacts the ribbon. If so trim 1/32" off the end of the ribbon & plug it back in. Or replace the buffer board to t-con ribbons. I fixed that exact vizio 70" and it worked great but I left it outside to be rained on about ten times now. Now at least the buffer boards will need to be cleaned with alcohol before powering it up. However now when your watching TV you could learn about chemtrails while growing your own bio weapons. Leave it on 24 7 until dry or discover a blitzkrieg proliferating black mold along with 16 million colors of fungus. Like playing Risk as they battle for supremacy between the layers of diffusers & polarized film. Perhaps I said to much!

[@mryuck44444448]

Couldn't you have tested the resistance between T-com output and LCD terminals to determine a short to avoid cost of repairing the T-com board ? Not that I have any idea what that reading should be.

👍Best Humble Teacher av ever known.. 🙏Owez making sure his students get it done right 😉👉.. Thanks a lot Sir!!

[@michaelpace4187]

Hey! Just wanted to give you a heads up on a possible fix. If you disconnect the ribbons from the t-con one at a time and 1/2 the panel comes up good then connect the ribbon cable to the other side of the t-con. If it comes up then t-con is good. These large Sharp panels have buffer boards on the side of the panels too(both sides). One of the side buffer boards is bad and you will see the burnt ribbon cable on the bad one. Just carefully rip the ribbon cables from the bad side of the panel and put it back together. You should be able to expose the buffer boards fairly easily. I have a 75" sharp that i fixed this way 2 years ago in my living room. The buffers on the opposite side of the screen are strong enough to power the panel.

[@ZachElder]

Michael Pace I fixed a 70” this way once

[@Vfh........y]

You're still the man dude. Just keep doing what you're doing. It's all good

[@binhminh417]

Thank you for the tutorial. I gave away two 50" Vizio TVs after troubleshoot the LED LCD because they were not worth it to fix them in term of repaired cost & stress. Vizio TVs were the most problematic TVs I have encountered.

[@felixcat4346]

I think the reality of your repair videos translate into a enjoyable watching experience. Most others are a waste of time. I give it a thumbs up, thanks.

[@shauno3697]

I'm a mechanic and I'm hoping I can find a parellel in how we confirm a diagnosis. I keep wondering if you could have added one more step in your diagnostics before you bought and replaced the parts. When I'm testing for a possible short in a vehicle module, I usually wind up disconnecting other components that may be pulling voltage down in a circuit. Older Chevy pickups, for example, are notorious for having shorted out oil pressure sensors. When they go bad, they pull down multiple 5V reference circuits and some people have erroneously replaced PCM's for it. Once I disconnect that pressure sensor, I get my 5V back every time. Coming back to your diagnosis on the TV, you didn't do your disconnect of the LCD connectors and test voltages until your part replacment failed. If you would have done a disconnect of those LCD connectors in your initial diagnosis, would you have gotten your 35 and 6 volts back across so many of those pins you tested? If the burnt transistor had any affect, would replacing that alone been enough to restore voltages to retest the T-con board with the LCD connectors still removed? I'd wager you could find those transistors in a Mouser catalog at a price that would be a much more affordable risk and let it be a reasonable billable item in your diagnostic fees. So whatcha think? Am I onto something, or do I need to go back to my corner and play quietly with my cars?

[@TampaTec]

True, troubleshooting is similar here, but I was trying to make this video super user friendly so anyone could do it themselves. Most viewers don't have tech experience and just want their tv to work.

[@b23norris]

I have the same TV I'm working on. On the Ribbon cable on the Logic board The top ribbon I do have the 12V bot on the bottom cable I do not have anything. Any ideas what would cause that? BTY this the best videos I have see on any TV repair.

[@GDFred88]

Is there a way to test the LCD before I fry a $35 board? That would be a really useful video. I have a dead screen with back lights still on. The sound was still playing until I turned it off and restarted hoping the system would reset. Do you have a video on how to test the LCD panel or the ribbons So I don't waste $35? Thanks so much!

[@hafcanadiana318]

So, is there a follow up video on how to avoid all the expense and time you incurred by some straight up, from the get go test for a bad panel? One commenter seemed to think you could unplug connectors (which?) one at a time to see how it affected the picture. But then how's that work if there's no picture to begin with?

[@jaybird57]

Can there be a short in the buffer boards that can be fixed? Or are the buffer boards just passive?

@@TampaTec yep , good info. i snagged one off the curb, tested good for about 2 hours, tested again the next day and lost backlight at around 2 hours, still had sound and i think video. does that sound like a bad led? thanks to your part one im fixing to check my backlight on volts and try to test the backlight volts.

[@fuzzygokoss]

I'm curious. Would you not be able to check resistance at the ribbon cable to see if it had a short? If so, then that test step could possibly save you from throwing parts at it?

My tv currently does what yours did after the new tcon board. Super upset thats its probably a bad display panel, especially since this was my 2nd since the 1st one offed itself in a similar fashion but still had a warranty 😔 Thanks for the helpful info i just have to decide if I want to waste $20 myself.

Hi, thanks for your videos it really helps.. but I have a challenge concerning this particular video you uploaded. There is a Sony tv with me that doesn’t show picture but it has sound, when I turned on my flashlight to the screen to see if it shows up anything I did but I couldn’t find anything on the screen, so i just want you to learn me more what could be the problem of the tv?

[@jmharris8679]

I like your video and the manner in which you explain in terms that the average DIY'er can understand. ... About a year ago my 47 inch Vizio LED crashed following a power surge caused by a lighting strike. I opened my Vizio unit and identified a scorched/bulging capacitor on my power supply. I ordered a replacement power supply from Shop Jimmy and installed the unit into my set. After reassembling the TV, I turned on the set which came on, but within 30 seconds I heard a crackle and the screen went dark again. I didn't reopen the set but assumed the power supply had blown a second time. Any idea what could have caused this result, I'd like to take another shot at repairing this unit but I'm not sure if it would be worth the effort. Any suggestions?

[@iamfubar1]

Even a "failure" is a win if viewed as a learning process. I now know that when the screen does THAT it means it is a bad LCD. As far as the parts...can't you remove the good parts and keep them for future use? I have several bins that I keep with parts in just in case I get compatible hardware that needs it.

[@jasonfrancolini]

HI Paul, thank you very much for these videos; gave me the confidence to try an LED tv repair myself. I have a Vizio M50-C1, circa 2015, that has a black screen and sound. The LEDs are all working, checked that. I have voltage, but everywhere on the power supply board that is labeled for +12V, I have +19V. Also, the pin labeled 3D_ON, which I am assuming is to turn the TCON on (am I right), has 0V with the TV on; I am guessing this should be ~3V. All other control voltages are present, and 5V are 5V. Pin 1 on the ribbon cable from the logic board to the TCON has 12V with the TV on, and pin 51 has 0V. I am assuming there is a problem with the power supply board given there is no voltage on the 3D_ON pin, and 19V where there should be 12V. Does this sound right to you, and should I look at replacing the PS board? Thanks for the very informative videos!

[@harryk1977]

Ordered a TCON off of ebay for about $40 ahead of watching your video, based on your diagnosis I likely have a bad panel as well .. sigh. I'm going to bust out my volt meter and test the same point you compelted - will share my findings. For anyone interested, this is on a Sharp 70".

[@Marcoosianism]

Is there a way to know what voltages are expected on any board at the voltage test points? Are they written on the board? ... or any way to look up that info?

[@P1ayD0hpaul]

Marcoosianism you don’t need to know that really. The voltage will or should be the same on most of the driver circuits. 6v as in this video. Just check the voltage and that’s what it should be, unless it’s near 0.

[@TheTrueJokerKiller]

Hello,Where do you get these repair boards?

[@michaelgabriel2228]

Sir, you said that you would show how to check if the main board was turning on the T-Con board but you did not do so. Could you please share that information? I'm not getting any voltage on the pins for the connector for the ribbon cable with or without the ribbon cable seated. I do have 12 volts on the board where the ribbon cable comes from the main board but no voltage where the ribbon cable connectors that connect to the panel are.

Is there any way to fault find the LCD before connecting the tcom board ? It's great when things work but hard to take when they don't. Keep on the sunny side !

[@TampaTec]

hmmm i will research and see. i will make a video if i find a way, "how to check for a defective LCD panel".

[@bmich833]

Good question. I was wondering too how to find the short through the ribbon cable too. Troubleshooting the boards is fine to find the fault, however, there is usually a reason why. I don't like throwing new components on unless its absolute that I know something else caused the issue.

[@Justinestabrook]

Take the bezel completely off around the whole screen and check the boards on either the bottom or top depending on your tv that has ribbon cables connected. If any of these are bad then it will cause a panel defect.
