I do need some definmitions.

Power controller? Same as a power supply?
This one has the PSU on the right side with no obvious
switches that I've yet found (maybe I have to change my
definition of obvious).
Breaker as I said is a just a small button, or,
it's hidden under a cover somewhere... more looking.

10.5

Not found (yet). This is one of the oldest PDP's made.
Second model, I believe.

> Try connecting the CPU mains cable directly to the mains
>(without the power controller)...

CPU mains cable sounds obvious, but what I have may be
the power controller cable(?)
Like I said, please define it for me.

Yes, I just looked around again with a flashlight, and peering under
the varouus grillworks, stopping just short of removing the PSU cover.
No circuitbreaker-switch. The two three pin ports that I mentioned first
up are located directly in front of a fair sized relay. Will try switching
there (and in front with the microswitches) at next opportunity, in a few
hours.
