just signed up here, because I found a way to get my 24“ Cinema Display back to life, which I have buyed yesterday.
The Display had the following symptons:
- no Image
- No backlight
- Not recognized by MacBook
- USB Working (iSight, Hub, Sound)
- Charging works
Looking closer to the logicboard, there were no burned spots or something else.
So I checked up the power cable to the panel, all signals there. Then checked the signal cable to the panel against the Mini DisplayPort connector: Bingo, Plug detection signal was broken. The disconnection appears near the Mini DisplayPort connector. Buyed a Hama Mini DisplayPort to HDMI Adapter and cut the HDMI receptacle. Joined the new connector to the all in one cable from the Display... Boom, Image is there, all is Working. Here are the documents I have used to re-engineer the signal connection.
Hope this helps anybody.
