Hi All,

This is my first post to this list, and hopefully not the last if I can come
up with anything reasonable to contribute. :-)

Anyway, I have a question on the above. I bought a Star Castle about a year
ago that ended up having a dead CPU and the breakers pop, just as Zonn
describes above. I've picked up another couple of CPU boards, one being
a working Star Castle, and I've placed it in. I found a couple of dead
power transistors on the heat sinks on the chassis and replaced them.
The breakers still pop, so I put it down for a bit, and now a year later
I want to go back and finish fixing it.

My question is this:
Is there a trouble shooting guide for this monitor anywhere?

Thanks,
-Chris
