Internal display not recognized
iMac 20-inch Early 2008
There is no picture at all on the iMac display. System Profiler shows no display being detected. Diagnostic LED 1, 2, 3 or on but 4 is off. A video signal is being generated as the desktop can be seen by logging in via Apple Remote Desktop. I haven't test an external monitor because I don't have the display adapter. I replaced the LVDS cable which had no effect. I'm assuming the display itself is bad.
Just looking for confirmation on this from anyone who has had a similar problem. If that's the case is the only feasible option to replace the LCD panel? Is it worth disassembling the LCD panel itself and testing/checking anything?
Here's a screenshot of System Profiler:
Is this a good question?
