I have a 15" Apple studio display hooked up to my cube. Some months ago I noticed the bottom half of the screen being dim and a the led error blink sequence "short - short - short".
According to Apple it means "video output wrong" but the display shows the same error code when hooked up the a powermac G4 MDD, unlikey error it seems.
I decided to open the display and check it's internal organs. Nothing seems wrong, but I noticed the following.
I took both light bulbs out and connected them to the inverter. The top bulb is working, and when I switched the bulbs, the bottom bulb (connected at the top connector) was working as well. Apparently the bottom connection doesn't get any power.
What do you think? Bad inverter board? Or could the problem lie with the logic board? According to someone on Macrumors it could be a heat issue (he had a similar problem where the problem dissapeared when the screen was hot enough - I haven't noticed this yet, the problem is continous)
