    Dell 2208wfpt dead

    Dell 2208wfpt and it's totally dead and after some reading it sounded like bad caps however after getting the power board out all the caps looked fine. Just for the heck of it I pulled out all the 330uF caps and checked with my ESR meter and they were just fine. I checked the fuse and it was ok I also checked the diodes and transistors. I have 165volts and the big cap but not sure where to go or if anybody know of a common problem with these.

    How about those 4 small caps (startup caps) in the primary side?

        Have you measured voltage on pins of the PSU output cable - any sign of a standby rail at all or are all rails totally dead?

          What is the voltage reading across the large 450V cap?
