    samsung white screen replaced as15

    hi people

    i had a samsung 40" with totally white screen, i ordered a new as15 from china and replaced the ic, it worked well for an hour but is slowly fading back to white
    im gonna open her up again and give the chip another blast from the hot air, but i also have another ic as i ordered 2, but i dont want to waste them if there is something else that could be causing it, also this ic did not have a heatsink or heatpad

    any advice i could glean before i carry out the surgery?

    maybe the voltage to the chip is too high.

          samsung galaxy ao2s very temperamental after screen replaced
          by Chrissygizmo
          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. ...

          White screen repairs
          by harp
          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...

          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
          by Ryan.man
          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...

          Samsung LE37B650 white screen
          by aczelkri
          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...

          ThinkPad P15s Gen 1, NM-C931 REV 1.0 touch screen replaced only works in UEFI menu
          by Yehuda170
          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
