A related question about this problem. I'm having the same issue with an iMac (2211) that recently had the HD replaced. In the process one wire of the 4 that makes up the LCD Temp Sensor cable was broken. It appears to have been repaired properly, but my question is...
Could one broken wire in the LCD Temp Sensor cable cause the problem of no chime and no LCD at boot (and no 4th LED)? Or is it more likely that the power supply simply needs replacing?
Just seems strange that prior to HD replacement all was well, then suddenly the power supply is dead?
Is this a good question?
