A little while back I had a completely rebuilt CPU lock up in my time warp, bench testing, diagnostic lights (leds) and forum people all say the 5101 chip is bad but no definite reason for it to fail. Since then I just put in another completely rebuilt CPU as it was an easy to get it up and playing. All the crimp connectors have been replaced, power supply and sound board have all new capacitors installed. Well last Friday night my friend was playing and it locked up again with the replacement CPU (both leds on). I have not done any more testing other than checking the power cord and sure enough the ground prong is bad (with a multi-meter hooked up I can wiggle the prong and it will lose continuity at times).
I am wondering if static electricity in addition to the bad cord ground could have caused these 2 5101 chips to go bad? It is the heating season (not news to anyone I am sure) and I heat with forced air which does create a very dry indoors environment and I do notice static shocks somewhat regularly in my carpeted basement.
