However, if the overheating LED comes on, I would check to make sure all the fans are operational. It is also possible that the PSU is bad too. I would verify the caps on the PSU before doing anything else. As far as the heatsink is concerned, if you removed it, then certainly you need new <a href="http://www.jwestsales.com/categories/Electronics/">heatsink compound</a>. Hello Alberto,

I have purchased capacitor kit for iMac g5 iSight 20". After disassembly of the logic board, I did find two of the capacitors apparently damaged and have replaced them successfully. After placing back everything in its place, the iMac doen't boot and the led #4 (overheating) turn red, the fan starts and after a few seconds the computer shutdown itself. For accessing the two bad capacitors, I did remove the gpu heatsink (and put back again later). Does anybody experimented same problem after fixing capacitors? Do you think that replacing thermal paste for the gpu will work? Thanks in advance. Alberto Hi. I have purchased capacitor kit for iMac g5 iSight 20″.
