Hi all.
I have a problem with this motherboard. It was bring in service with 'turns off by itself after few seconds'.
Replace North bridge, south bridge - no result.
Bios preprogramming - no result.
Test with different cpu/memory - no result.
When measure board, I found short on PL8. On PQ29 - 19v (5 6 7 8 legs)
LGATE, UGATE - 0V
VOUT - 0V
Replace PC218, PC96, PL8, PC97, PR119
I can't find where the hell is short...
PU8 also replaced - no result.
In these few seconds, before shutdown, I check cpu and memory voltages - OK. 3.3V and 5V - OK.
Identification of components is very hard on this board, because there are no labels on the board. If someone can help, please...
