    Hi,

    I bought 3 screens and 3 controller boards
    the controller boards are M.NT68676.2
    The screens are
    * LP171WU1(TL)(A6) - not working
    * LP171WU3(TL)(B1) - working
    * LP171WU3(TL)(B3) - working

    Here's a video showing the screen that doesn't work


    Any/all of the *3* of the controller boards work 100% with either of the *2* working screens.

    Minor firmware differences and problem:
    I asked the seller of the 3 controller boards to program each of them to match my screens. He botched the firmware for at least one of the boards. It shows either of the screens has a resolution of 1024x768, but I can still force the full resolution in software on my computer and it works 100% at full resolution.

    Can you please tell me if
    1. Is the LCD panel damaged or is it a firmware problem
    2. If the LCD panel is damaged, is it repairable?

    Please elaborate?

    Many thanks and kind regards!

    Welcome to EP.

    What good is voting for?

    It can be either of the things both a firmware problem or a bad display.
    I think you should contact the LCD manufacture(Philips? ),it should have warranty and tech help.
    You will get the best help from them.
