Power supply used in HP Slimline Bookshelf PC Series
An HP Slimline S3321p appeared dead.
suspect: Power Supply
HP P/N: 5188-7520
Delta Electronics P/N: DPS-160QB A Rev: 01 F
It has a mini motherboard connector so I couldn't immediately hookup another power supply to test.
after popping the cover on the PS
PCB
Delta P/N: DPS-160QP
I noticed a swollen cap
decided I would give it a shot so I disassembled the PS.
Upon further inspection, hiding under the motherboard bundle, I find more blown/swollen caps
Back side of board looks good (???)
After digging through my capacitors I have them all except 2.
The first cap I saw was 1500uf 16v so I decided to substitute in a 2200uf 16v (???)(red oval).
The 2nd was a 1000uf 10v (HD)(yellow oval). I did have a 1000uf 10v (HM), but I didn't substitute. (???) Old one looked good so I left it. (???)
If I read the board right:
C904 1500uf 16V substituted: 2200uf 16v
C152 1000uf 16V
C303 1000uf 6.3v
C103 1000uf 10v
C302 1000uf 6.3v
C102 1000uf 10V
I get them replaced
put it all back together and the computer fired right up.
great site - thnx
