Hi guys this is a TV that is at my friend's house he needs help repairing I told him I'd ask if it's even worth fixing. I will have all specs tomorrow but could this be panel issues and unfixable. Any thought?

Re: Top screen color fading
It looks like it could be edge lit with the top edge not being illuminated. -
Re: Top screen color fading
How new is that TV? Looks like later-2010s to me, and if it is, 99 percent, it's shit LEDs! Or LEDs with shit mounting!Last edited by RJARRRPCGP; 11-05-2019, 05:48 AM.ASRock B550 PG Velocita

Re: Top screen color fading
This is a UN75F6300
Version UH02
2013.
I found a few posts on this actual TV but they never seemed to get to the bottom of the issue. So I did test the LED capacitors and I got 336 in the lower capacitor and fluctuation between 533v-561v on each of the top three capacitors. Now I'm assuming I'd have to open the whole TV up anyway to check on the LEDs?Attached FilesComment

Re: Top screen color fading
If you check the dc voltage across the two legs of each of those capacitors it cannot measure more than 400V, the rating of each capacitor, otherwise the capacitors would explode.
I can't quite read the print on the circuit board photo but it looks like the led drive voltage is 237V @ 250mA
Shopjimmy do a repair kit for this board which may give you an idea of what to check out.

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
Picked this up to resurrect.
When I plugged it in it comes on for about 1 minute... after a minute the screen blacks out and I gets blinking red lights on the power button.
I read that a common issue with this model is a failed BGA so I ordered a replacement on eBay.
Sometimes the TV would produce an expanding blob on the screen before going black.
See Video here
I ordered a replacement board off of eBay and installed it tonight and got the same behavior.
Did I get another defective board or is there an issue with...
