My Prime 2455's PSU died last week. A replacement has been
offered and will undoubtedly arrive sooner than a repair
will take place. But I have to deep-six this monster, as
they just don't make them anymore, and buying a used one
from a reseller is likely to be cost prohibitive.
So, I'd like to eventually repair it. It's a monster, and
potentially lethal. From poking around with a voltmeter,
I can see that it chops the AC to DC and doubles the voltage
to about 280 volts, one positive supply, one negative supply.
From there, I'm lost. Has anyone every written up a
general
description of troubleshooting and repair techniques? Is it
even possible for devices that vary in design not only from
manufacturer to manufacturer, but wven model to model?
