TECH: Xevious Power Supply

[brian...@boeing.com]

I turned on my Xevious the other day and got nothing but a white screen.

Opened it up and found out I'm only getting a volt or two on the 10.3V
unregulated going into the reulator/audio II board.

Ok, Now the questions:

1. Does this mean the transformer is bad on the power supply? I haven't opened
that up down there yet. Is there anything else down there that it could
be? Should I even try to fix the original power supply?

2. I tried to put the 12V outputs from a PC power supply onto the 10.3V
unregulated going into the regulator/audio II board and that works for about 5
seconds and then the PC power supply shuts down. I'm guessing that it's doing
this because it doesn't have a load on the 5V outputs?

2a. I still need the regulator/audio II board to amplify the speaker outs,
so it there a simply way to keep the PC power supply from shutting down with
only the 12V outputs run? If so, will I damage the regulator/audio II board
by running it with 12V?

2b. Should I hack up my wiring harnesses going to, and coming from, the
regulator/audio II board and put the 12V out from the PC power supply into
the regulator/Audio II board, and not use the 5V outputs of the
regulator/audio II and put the PC power supplies 5V outs there? Is this going
to do anything bad to the regulator/audio II by having the regulator not
loaded?

I would prefer to keep it all original and just repair the existing power
supply, put I haven't found any kind of docs on repairing linear power
supplies. If this isn't possibly or practical, then just using the 12V outs
of the PC power supply is the next prefered option.

Thanks,

Brian
