Chosen Solution

I noticed on YouTube there is a video showing the replacement of the power supply, but no guide. I figure I’ll use the HD replacement guide to get into the case, then refer to the video to replace it. Just a thought. If I get my act together before I replace the ps, I may create a “you can also replace” guide hooking off the HD replacement.

Looks like this machine could use several guides. Use the front bezel guide as a prerequisite. iMac Intel 24" EMC 2134 and 2211 Diagnostic LED’s Next do the display as a guide. Then you can go to the logic board, then the power supply. It may also need one for the inverter, CPU and GPU replacement and upgrades.
