hi all, i have this all in one computer that has a short or i think so, because when i plug power supply psu led start blinking. tried another psu with same result.


if i check pq127, pins 5-6-7-8 are shorted. if i remove pq125 led wont blink, but i need a schematic to fix this one.

mainboard is quanta wj5 or hannstar mv-6

best regards.

Re: hp pro 3420 daowj5mb6e0 shorted.

got another cpu and now is fully working

about bad post: removed ram, put it back and that issue is fixed too

Re: hp pro 3420 daowj5mb6e0 shorted.

mosfet arrived and replaced just the one shorted. now pc power on, but when loading windows it do osme dots and then stop working. after a while give me bsod about a page fault. tested hdd all ok. tested ram all ok. that make me think
1) bad gpu on cpu
2) have to change also other mosfet that could get damaged...

ps: sometimes pc doesnt post after a reboot.... if i turn it off then on i got the hp logo.

Re: hp pro 3420 daowj5mb6e0 shorted.

finally with psu lab i found bad component. it was pq82 : 73t03gmt 13136g, but cant find that component to buy....

edit i found it's a AP73t03gmt n channel mosfet, but i need asap and express ship is 40$.... so im wondering if there are any compatible mosfet that maybe i could find in my country..

edit: while wa looking for an equivalent, my supplier told me it was in stock
