Everything on that line reads 0 resistance to ground. With the board out of the case and not plugged into anything else, the voltage is 20v and it goes from 0.07a then to zero every few seconds. the only two chips that even get warm are the T2 and U7650 and they just pulse on and off along with the amps reading.
On a known working board I see the none of the same lines appear to be shorted to ground, although they do have a very low resistance to ground. How in the world would I be able to isolate if there is one bad cap on these lines or does it indicate an internal short on the CPU? None of the caps look bad. I've looked at them all many times.
So I guess the CPU is dead then? The readings are not the same with a working board. On the working board the same lines all read 1 ohm and in continuity mode they will give a quick beep then stop on the multimeter, but on the broken board they go straight to zero, and a solid beep on the multimeter.
Oops! Yes, you're correct. Injecting 1v through that pad shows nothing individually getting hot, but the entire area at 10.48a and when touching the power probe it's hot at the tip with a little spark. I guess CPU is done.
