Wow, what a response.  The camera is Ademco acm574tpx.  It's
monochrome and I don't have the lens fitted.  No idea of its age and
no idea what happned to it as I got it from an online auction.
There's some capacitors inside and I'm tempted to buy an Atlas ESR
meter to test them.

When I first switched it on, I saw a fuzzy image on the screen and
then it all went black.  It has an internal power supply which is
20-29 V AC.  I tested it with a DC supply.  It would be nice to repair
it as it's a decent camera.
