I recently bought a Performa 450 which was in very good condition, no visible leakages, blown-up batteries etc. When I power it on, I can only hear a clicking sound from the speaker. Fan is working correctly. I measured output of the PSU and so far it looks like I'm getting wrong voltage on +12V and +5V lines. It fluctuates around +8.5V and +2.8V respectively. -5V line shows correct voltage though. Do I have faulty voltage regulators or should I recap the PSU? It's one of the Dyna Comp (not TDK). Close-up photos attached.
