    Viewsonic VA2406M-LED Whitescreen

    Hi!I have a Viewsonic VA2406M-LED, and I cannot find the problem but I should be able to repair it! My monitor goes white when I turn it on. I don't know if the problem come from the power board or main board.

    I have taken the whole thing apart and back together and still the problem persists. I don't believe the caps are bad but maybe you will have a better opinion.

    The pictures of the boards are here: http://imgur.com/a/2LKVZ#Q7SVDjM

    Any help would be much appreciated

    Caps look decent
    BY white screen, I assume you mean that the screen lights up but has absolutely no image ?

    If that is the case, you may not be getting voltage to power on the pixels of the screen.
    Based on limited pictures, it looks like the power to do this is probably traveling through the flat white 30 pin ribbon since I di not see another set of wires that would feed the lcd panel. if it is powering through this ribbon, it probably takes 3 or 4 of the first pins on one end. Check that ribbon contacts at both ends first for any possible damage or discoloration

    if the ribbon contacts look ok
    you'll need a voltage tester to check the pins for power

    a picture of where the ribbon connects to the back of the screen might help

      Can we see the picture of the back side of the LCD panel?
