Re: Samsung LN37A550P3F replaced Caps, white screen only
hm, how sure are you about this?...no offense but you are a newbie on this forum so do you have any background knowledge/experience or just kinda taking a guess
i don't feel like buying an inverter if its not going to fix the problemComment

Re: Samsung LN37A550P3F replaced Caps, white screen only
Have you ever heard of flash lights test to see if you do have pictures on the screen or not when the backligts no longer works due to inverter/lamp failuer?
Lets see now, you have backlights but no pictures on the screen as you can see it just has the glow in half of the screen with no pictures at all, using logic based on that the backlights are just the light sources so you can see the pictures on the screen, it is not related to how the pictures are created by other circuits. So if even you have partial lit screen, that is not going to stop you from seeing the pictures on the screen.
BTW, there is problem with the inverter, the whole inverter will be shout down and will not allow just part of it to work.

So you have the lamps sitting horizontally to light up the screen, there is no left side lamps or right side lamps to be turn off in just one side, the whole inverter circuit will be shutdown if it detects just ONE error in the inverter/lamp.Last edited by budm; 07-12-2015, 01:44 PM.Never stop learning

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 -
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... -
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... -
Hey guys,
I have a Samsung LE37B650 screen with the following symptoms:
- Image suddenly turned into almost completely white while I was watching a movie. I can make out some details, but they are very faint. There is definitely an image there, but very very bright and maybe inverted colors.
- If I unplug the cable between the main panel (that has all the video in-out ports) and the tcon board (T315HW02 V3 CTRL BD 31T06 C03), the screen is black as normal (there is backlight and it is masked by the pixels), but of course there is no actual... -
original screen was BOE NV156FHM-T07 with On-Cell Touch screen I²C
replaced with what was in my stock, which is IVO R156NWF7 R2 which is also with On-Cell Touch screen I²C
now touch screen works perfectly in UEFI BIOS menu & boot menu. but not working in OS, tried windows & linux too
with original broken screen i can see in device manager touch screen in human interfaces
but with the new screen it's not showing in device manager
is it lenovo blocking it? is it driver missing?
I²C is a headache
