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...

this is screenshot of damaged area:

Thanks, regards,

Raise the output №2, PL8 and find out which side is short. If short in PL8, check PQ30, and if the part of the North Bridge, the short or directly underneath it.
Short is - 0 Ohm.

Sorry, i can't understand "Raise the output №2".
PL8 and PQ30 already replaced.
Do you have boardview for this board?
Thanks for your support.

It does not say that PQ30 replaced.
Then lift up the Northbridge and measure whether it took short.
It turns out that the short balls stuck together or makes himself or Northbridge.

Little update. Lift the NB, clear pads and measure, I think short is somewhere before NB.
Because my donor boards are in my home, I try tomorrow with another PL8. PQ29 and PQ30 replace with no result.
Anybody with boardview, please? This board is terrible for work..

Try connect some regulated power there and look which component heats up.

Hi, I will try it. Thanks.
