No beeps, no power on. Power supply test good.
Only symptom is two transistors near main power connector get very hot. One is a 3.x Volt regulator.
I pulled 4 caps from the immediate area an all test ok. No caps appear blown.
Probably a lost cause but maybe someone has an idea...
I have a PSU test device that draws current and measures voltages. Also I tried a second PSU that was known to be good with the same results.
BTW, I looked up the hot transitsor and it is a 3.x Volt voltage regulator so I am guessing something in memory controller is shorted. Looks like the board is just dead and headed for the trash pile.
