    Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
    by lostone
    Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

    First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
    When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

    A2289 won't power on
    by sauce
    Hi,

    I bought a faulty A2289 for myself.

    The USB-C meter was stuck on 5V.

    After remove the board the U3100 was corroded and also around but quite light.

    So I clean the U3100 and see R2834 in bad condition and its value was not good.
    I replace it and not the USB-C meter shows 20V, the fan is spinning, CPU is hot but nothing else no picture.

    The USB-C meters shows a very low current with all connected. It starts at 20v few mA and then stays at 20v 100mA.

    How mush current the board is supposed to take without nothing...

    ASUS X512DA BIOS MOD
    by Oficinadopc
    I'm trying to enable this Asus X512DA. This model came without backlit and I ordered a keyboard with backlit. As I've been searching on the internet, It seems that the bios as to be modified at the offset DD to 7E. Since I don't have enough knowledge to the task, is there anyone who can make it for me? I attach the original bios file.

    Really appreciate the help...
