greetings!!!

can u pls help me point out the trouble in the atx psu i am trying to
repair. it powers up but its voltage is lower than its specifications.
yellow wires- (only +7.5 volts, should be +12v, red wires - only 2
volts, should be +5 v). what could be the problem and where do i start?

thanks in advance,

ian


Hardly worth messing with, but I would first look at the bridge
rectifier to see if one of the diodes opened. A low input voltage could
account for low output voltage if it would still worked.
