    White screen please help?

    Please help me understand what has gone wrong with my monitor so I can throw it away!
    I have a HP1950g monitor that has suddenly decided to display only the backlight. Reading through the web encouraged me to have a go to fix the problem hoping it would simply be a loose wire. Having got the monitor apart I discover the cables all appear to be secure. Fearing a blown capacitor I strip all the boards out looking for the tell tell signs of a faulty cap'. None show up but undeterred I am able to obtain two other monitors identical which work but have water damage in the LCD spoiling the image. I strip all boards I can and swap them into my monitor one by one with hope fading until I'm left with nothing else to swap out. The only board left is the one attached directly to the LCD screen itself.
    Is it possible to change this, or am I waisting my time?

    You usually can't swap that board. However, I've had a fuse blow on a 19" Dell monitor, causing a white screen. It was on that unreplaceable t-con board.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
    For service manual, schematic, boardview (board view), datasheet, cad - use our search.

      Post pictures of the t-con board (usually a slim, long board attached to the panel at the top of the monitor).

      For troubleshooting, you will need a multimeter.

        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...

        HannStar Hanns-G HC194d LCD monitor repair
        by momaka
        Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

        A2141 Screen replacement. Boots screen freezes on Apple Logo 1/3 status bar unless connected to second monitor.
        by abajor
        Having this very weird issue.
        The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.

        I swapped with a working screen from an A2141 waiting for parts.

        The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.

        The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...

        Sharp LC-65Q620U White Screen
        by EazyBone
        Another TV topic!!
        I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.

        The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.

        Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...
