One night the power to my 3B1 went out as if the AC line had been yanked. After checking that the fuse was OK, I attempted to power back on. All I get when I do this is the LED's on the keyboard lighting up, going out, and lighting back up at about half-second intervals. Also, the speaker makes a clicking noise at these same intervals. No fans, no disk, no CRT. Naturally, this is the system which is out of warranty, no maintenance, and where most of my software resides. Does this sound like the type of problem that would require complete replacement of the power supply, or might it be just some component that could be easily replaced? If it's the latter, how easy is it to remove the power supply from the system and take it to someone who could repair it? I'd like to avoid moving the whole system. I'm sure a whole lot of people would be interested in having third party maintenance on the Unix PC, but I don't know of any and it's been a long time since anyone's heard of Amperfax. ...pacbell!safari!dave ...tektronix!reed!omen!safari!dave ...ihnp4!safari!dave

I had a similar thing happen a couple of weeks ago. I called around and
found a local company (in the Yellow Pages under computer service) which
fixed the supply for $100.00, flat rate. Power supplies are all pretty
similar, and this should not be a problem for them if they can just figure
out how to open up the box.
BTW, mine turned out to be a shorted filter capacitor. Kills the sucker
dead, guaranteed.
Hope you have similar good luck.
