Re: white screen on samsung 37"
Looks like Bad GAMMA IC.
Probably this is the T-CON in his TV with AS15 GAMMA IC.

Re: white screen on samsung 37"
You haven't open the screen yet, right?
Once, I had something very similar and it was a pot on the LCD PCB, it got knocked off the board by me, when I was putting the screen together.Comment

To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment... -
Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
Ive eventually managed to get it on and working but it's very temperamental...
The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...05-26-2024, 12:05 AM -
Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and then tv won't turn off.
No picture. No sound that I can tell. Backlights are on and have been checked. Flashlight test no image on screen. I replaced the Eprom chip hoping that was the problem but nothing changed.
Please help. Thanks in advance! -
HI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when... -
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...
