    Ok so I recently acquired another HD44780 compatible lcd blah blah...but this one seems to want 12v to power up? Anyone ever seen this before? It is powered with a 3-pin connection so I am thinking either it takes 12v or that Dell used a riser with a +5v supplied 3-pin connection.

    That is real strange although it could source power from a motherboard fan power connector.
    I had a SED1520F that needed 12V from a fan power connector. It needed 12V because of the LEDs, they were ultra bright one that hurt your eyes in darkness lol.

    Anyways, hope you sort it :thumb:

    The 12V looks like it is for the backlight, and since that cable has 14 wires, I would think that is the case. Pins 1 and 2 on the cable are power for the LCD (1=gnd, 2=+5v) and pin 3 is contrast.

    If you disconnect that 3-pin header, than the LCD should still work, but the backlight should go out.

    I got 5 of them in a box - pulled them out of Dell PE5133's that were going to the dump. they use standard pinouts and work with LCDC - replaced mine with a VFD from farnell.

    you ever power up the backlights on them? I had this one on for about 5min and it seriously overheated and starting turning black. Luckily nothing was damaged but I am thinking it only takes 5v for the backlight.....
