Hi, My 23’ Apple Cinema display stopped working. It switches on but my mac (and other macs I tested) stopped detecting it. So no image… Any suggestions what I should replace/repair? Thanks! a-

If the display is not even recognized by the system, I would try listening if even the fan starts to roll. Otherwise I would go further checking the power voltages first. But yeah as @SW said You might as well quick try and see the Panel with a flashlight if you have a weak image without background lighting.
