  • LB080WV3 (A3) LG Philips LCD

    Hello all,

    I have received a small car display probably 7 inches or so the model is:

    LB080WV3 (A3) LG Philips LCD and also this is the closest schematic to pinouts i could find but its for the (A1). If I'm reading this correctly, I have 8-pins, and the colors go:

    1] Orange: Display mode control
    2] Blue: Brightness Control
    3] Yellow: Battery+ (power supply)
    4] Black: Ground
    5] Green: Brightness Control / Impedance Selection
    6] Red: Display Enable
    7/8] Black/White: pins 7 & 8 twisted together.

    Now, the schematic only says #'s no colors but this is how I assumed it is. Let me know if this is correct.

    I'm trying to power it thru a normal PC ATX Power Supply with the pins 13/14 and 8/9 jumpered so it tricks the PSU to thinking its hooked up to a motherboard. So the PSU boots up just fine, but I can't seem to get any power to the LCD display, I have yellow on the yellow molex connector for the +12v and the ground right next to it according to wikipedias info on molex connectors. Havn't tinkered with the display yet but shouldn't I at least see the backlight come on with this setup?

    Do I need some sort of regulator or something? then again I have no idea if this works, a buddy of mine gave it to me for me to mess around with.

    I'm currently going to school in electronics so I know most of this stuff.

    If you need any other info please let me know.

      You need 12v to the red wire also. This is the ignition wire.

        Thx for the reply,

        I tried that and its still a no go, does it sound like this screen is a dud?

        P.S. i've powered a laptop with an ATX power supply so i know that the supply is working.
