ah, the memories. TV i'm using right now I did this repair on after watching one of your vids. I replaced all the strips; just bought a kit online. Big 42" Was a pain to handle given my limited space, and all the parts, but I managed.

That's very clever sliding cardboard underneath the lcd and also using the heat gun to melt the solder and only later adding the led. I probably would have placed the led and then hit it with the heatgun only to ensure the life of the led is shortened as a result of my stupidity.
hi, i have the same lighted up screen and dimming till pitch black/ vanishing light issue, but it occurs due to lightning strike. is it possible the led fail due to lightning strike?
Hello!! Good stuff!! I'm looking to repair my 65" Vizio. When I power her up I get the flashing indicator light followed by a quick appearance of the Vizio logo and then it quickly disappears, the backlight goes off, and then there's no picture visible. I can see the picture with a flashlight. Im an electrician so my gut instinct tells me it's a power supply LED driver issue. Is there any way that I can track this down further. I have already eliminated the main board as the issue by swapping with a known good one. I figure the power board and LED driver are on the same board and I can get the board for under $30, so I'm willing to take the chance with that. Not too sure about replacing the LED strips themselves.
What you are describing sounds like a bad LED backlight like what I fixed in this video. You can replace the backlight strips rather than the individual LEDs (which is usually not what I would recommend anyway).
Seen a couple of your videos pop up as im trying to fix my 70 inch vizio TV. Bought it a few months ago at a garage sale in good working comdition...now it is having issues. The screen has horizontal lines when the screen is on. The lines arent in the same areas all the time but change based on the image being shown. Do you have any videos on something like that? Thanks for the helpful sharing your channel does. Too many places just recommend tossing it and getting a new TV...hoping thats not the case here.
@@FrugalRepair thanks, I've been watching them on repeat and still not quite figuring it out. I'm using electrical tape and not sure if that's the problem...maybe I'm just not the guy for the job. Thanks for the help, your videos are very well done and are interesting to watch and learn from
Hi I've got a 60" JVC LED TV it goes on and shows the Logo and then the screen goes black power light on but black screen any help with that please tia
Your adress can be seen on the bill from ali. I have a 4 year old LG Oled, where the standby light keeps disappearing more and more often (TV can't be turned on). If I disconnect the TV and plug it in after 2-3 minutes, the standby-light comes back and I can turn it on again without any issue. I would guess it's a capacitor problem on the power supply. What do you think?
Good eye, but that's not my address. That's part of the seller's in the Philippines. For your TV, I don't know. I doubt its part of the "capacitor plague" on power supplies since it's newer. You could try heating the caps on the power supply up with a hair dryer and see if the tv turns on. I would probably first try to trouble shoot the button bar and/or remote sensor. Maybe there is a short on there. You'd also want to check the standard voltages and if the main board is sending the "turn on" signal to the power supply when the power button is pressed. It may be labeled "PS_ON" or similar.
@@FrugalRepair Thanks for the response. Did some research in the meantime and this "intermittent standby led" seems to be a common issue in the 2020/2021/2022 LGs. Unfortunately, most repair channels just show the power supply swap, not the real repair of the board. Electronics repair is a hobby of mine, but the problem is, that I can't open it an then wait 3 weeks for parts...my kids wouldn't be very happy with that. I guess I'll swap it and repair it later.
@@FrugalRepair Update: I changed the powersupply-board, TV works fine again. This also fixed some other issues like repeatedly freezing firetv-stick and remote-control-pairing every time. Strange.
Is it the backlights that are flickering? Or the image? You should try turning down the backlight brightness to like, 40% (or as low as you can go and still watch it) and see if the problem still happens. I'm wondering if your issue is heat related. You can also take the back cover off, put a small fan on it and see if that makes a difference. That may be a model later than when they had the bad capacitors on the power supply but that is also something to check (look for buldged caps).
I cannot answer that until I take apart the TV again but at the moment I am using it. The super glue evaporates as it is drying and fogs up the lenses leading to a foggy coating on the lenses. There is a gel type super glue that doesn't go white foggy.
I still take the tv home even if the LCD is broken because the TCON board and powersupply can still be harvested giving another TV another lease on life
This is not a good method because other LEDs will burn soon and you have to remove the panel again to replace them. It is better to replace them all at once.
So do we all but that's not what this site is all about so if you think it's not worth it to fix the tv then best you watch a channel about fixing cars instead of leaving negative comments
@@Hobbyscrapperaustralia obviously your time is worth nothing. This is not a job that a beginner can handle. He makes it look easy so a novice can spend a day and still not be successful. So risk reward ratio is not there.

1$ in parts.
100$ in labor.
Great job btw.
Nice!

I’d recommend watching my two videos on fixing with tape. I cover testing methods and explain issues related to horizontal lines

What have you tried to diagnose it? Did you use a flashlight to see if it's a backlight issue?

Hello I have 2012 samsung smart TV. That will work for days and then out of nowhere start flickering on and off.
Is it the backlights that are flickering? Or the image? You should try turning down the backlight brightness to like, 40% (or as low as you can go and still watch it) and see if the problem still happens. I'm wondering if your issue is heat related.

That may be a model later than when they had the bad capacitors on the power supply but that is also something to check (look for buldged caps).
But don't use stuper glue to stick lenses back on as it turns white when cured and messes up the lens.
If you are only using adhesive on lens legs to the PCB, how would it mess up the lens?
I cannot answer that until I take apart the TV again but at the moment I am using it. The super glue evaporates as it is drying and fogs up the lenses leading to a foggy coating on the lenses. There is a gel type super glue that doesn't go white foggy.
I still take the tv home even if the LCD is broken because the TCON board and powersupply can still be harvested giving another TV another lease on life
Vizio had crap quality. Consumer Reports even stopped recommending them.
I'm scared of those lcd screens especially with those driver brothers.
This is not a good method because other LEDs will burn soon and you have to remove the panel again to replace them. It is better to replace them all at once.
I mentioned this suggestion in the video. I don’t know if you got to that part yet or not

This TV is max $100 used so probably not worth all the risk and time. I save money by doing DIY car maintenance where u can save thousands.
So do we all but that's not what this site is all about so if you think it's not worth it to fix the tv then best you watch a channel about fixing cars instead of leaving negative comments
