Ok, people , looks like ive got a power supply issue on the 2gs
I noticed it was having difficulty turning on. You can hear tht fast audible chirping from the power supply. Thinking it was the PS, I pulled the memory card.
With the memory card pulled the computer will turn on. However it ticks several times as the voltage ramps up then it turns on.
I can get it to turn on if I remove most everything from the unit
If it hasnt been running for a few hours it will come on with the 1 mb ram card. If you shut it after a few minutes and try to restart it, it just does the chirping noise
The measured voltages without the memory card are
+10 should be +12
By recommendation Ive replaced the 4 small capacitors C6 C7 and C8(3 near the transformer) as well as C12
any suggestions? Any testpoints I can check to determine component failure?
