Hello all! With not being able to get replacement parts anymore, I have three main power supplies in a repair shop in hopes of getting two working power supplies back in working condition. Recapping and fine tuning voltages went fine, but apparently an IC chip that controls the light gray 'Power Okay' 5v circuit is bad on all three units. They're working on finding replacement chips, but I'm wondering if anyone has already navigated through this issue and would have recommendations.
Further information: The 5v POkay signals the motherboard that power is stable and it's okay to power up or conversely to power down. The center fan would generally follow the motherboard. It also sends POkay signal to the PC board behind the LCD screen, which on these units have gone from blue lines to an unreadable solid blue quite some time ago.
