Looking for some help here with this macbook , the owner stated that it was working ok then all of sudden it turned off and wouldnt power on again. What i got on the USB AMP METER IS 20V ---------- 0.27AMP
And 7.78 WATTS

I realise that the fan spins and U1800 gets super hot and no boot , I have not done anything yet , Please help me out to diagnose it .

If PCH gets super hot, it is probably damaged.
Check diode mode to ground readings on PCH and CPU coils.
Also check the other coils.

I ran diode mode to ground and most of the lines are shorted I think PCH needs either reballing or replacement, the coils are also on low readings the other coils read well, I will try to reball the PCH to see if that does anything.

Do you think a massage to wood foot helps for something?
If PCH is shorted, throw it.
