    I just purchased an ADC to DVI adapter (http://www.amazon.com/Apple-M8661LL-Display-Adapter-4038234011420/dp/B00011KHT2) and was looking to hook this up to my Xbox 360 since I had no other use for my 23'' Cinema display. It isn't currently working as the display currently is flashing on the power button and the screen is black. (I'm running my Xbox to a HDMI->DVI converter that I then plug into the converter's cable)

    If there are any fixes to this problem ANY help would be greatly appreciated!

    Thank you much!

    edit: Also, it works when I run the cable to my macbook and connect the ADC to DVI adapter to a DVI to mini-display port connector.

    You're getting that flashing light because the screen has a hardware problem. What is the flashing light sequence?

    it's three flashes separated by a fairly long pause. I tested the hdmi to DVI converter separately and it is functional.

    I believe that indicates a problem with the inverter or internal power supply. I think it's an inverter. Those are about $50-$100 to replace.

    If it does work correctly with a Macbook, try plugging it into the Xbox with the video cable going to the Xbox. I think the ADC screen needs a USB connection to activate. I don't think the Xbox's USB is able to properly activate the screen, but you can try it.

    I have the ADC connector, it does indeed need an active USB connection. I am not sure why.

    Because the USB controls the backlighting, screen sleep functions, and one of the touch buttons.

    I've tried connecting the usb to both the laptop and a iPhone charger plugin and neither has helped. Furthermore, it's important to note that when it's plugged into the macbook and functioning the USB is NOT plugged in.

    The Xbox may not be sending the proper activation signal to the ADC display. It likely won't work without building a direct adapter of your own.

    any idea how I would do that or if anything like that is available for purchase? I already invested a lot in this setup and might as well see it through (if possible...).

    Appreciate the feedback.

    Strip down the cable from the screen and solder on a DVI cable to the right wires and hope it works.

    The OP would still need to find a way to provide power to the display (the ADC<->DVI adapter not only acts as a physical cable adapter, but also is a power supply for the display - the Macs the screen was originally intended for provided the power through the graphics card)

    A G4 Cube's power supply is a good choice as it provides the correct power requirements to power the screen.
