    laptop hp g72 b52sf screen problems
    by jean luc ferre
    Hello,
    on this laptop hp g72 b52sf i have screen problems as you can see with the photo joined in attachments.
    the used graphic card is "intel hd graphics" and the id of the integrated screen is : "monitor/SEC3354".
    i verified the driver of the pΓ©ripherals and they are ok. i verified the definition and settings of the graphic card and of the screen : definition 1600x900 and refreshment frequency :60hz. (they are the sames for the graphic card and the screen).
    i don't understand the reasons of the white stripe at the bottom of the screen below the task...

    Samsung UE55JU6800K half screen dark
    by Chrissygizmo
    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...

    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...

    LG 55UH6150- trouble powering up, then half lit screen (pictures!)
    by valvashon
    The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
    Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...

    TD Systems K50DLG12US half black and half white screen
    by Raulnn
    good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?

    By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the...
