I have mac mini 820-2993 there are no schematics available, the board is in short. Power supply works. I inspected board carefully and didnt find any bad capacitor or other deformation. Board is not water damaged.
Well at this point I tried simply supply power to the board directly in hopes something get warm.
CPU got warm, then I started picking coils to find out if it is something in between or the CPU, slowly and surely I got all the way to COIL next to CPU. Removing that coil removes short from the board except on CPU side ( I assume cpu side). So I gave it 1v to make sure, and cpu get warm. Did I actually discover short or it is simply low resistance power rail?
My question is did I ruin CPU when connected power to the board and warm up CPU?
I am not sure what alse can I do in this case,could any one suggest troubleshooting ideas that would help?
