This iMac was powering on at first but experiencing the fan running at full speed, even when shut off. I would unplug the power cable, then plug back in without turning the iMac back on and the fan would spin at full speed again. The client took the iMac home over the weekend, but it powered off on her, and now there is no power.
Here is what I found. Power supply is good (had known good power supply I swapped).
Back to the motherboard:
I used a thermal camera and found U7100 appeared to be shorting, so I removed this chip and still had shorts on the following pins:
4,3,21,20,48,46,42,32.
Because where these appear to go, REG_CPUCORE_VSEN being one, does this mean the CPU is fried?
Thank you!
