good day,

well i have here atx compaq psu that only spins its fan a second then
stops.its first symptoms was low voltage. I measure the voltage on red
- +4 , yellow - +9 should be +12. Now when i try to turn it on again,
it only produces a jolt of energy then fan stops. is it a shorted
component on the secondary side? other possibilities.

regards,

ian

What part number?
