So i had a fully functioning SC1435 until i plugged it in and powered it on one day. Here's the status:
Power light turns green when power cord is applied, no fans, no POST, no beeps
The system status light blinks amber three times (only when power is first applied) - no other diagnostic lights on (numbers 1-4).
Already tried: CMOS reset (jumper), pulling the battery, pulling/re-seating memory, CPU's (every other connector, etc). System board looked like it was in good shape (no visible bad caps), so i ordered a power supply. New (used eBay) power supply arrives today and same thing :(
I can also hold the power button down and turn off the light, turn back on - but no server activity.
Any guesses? Bad mobo? another bad PS?
In the meantime i'm seeing if i can find another power supply lying around to test with. Any suggestions are appreciated.
