KDS VS-7e 17" CRT keeps turning itself off

This CRT has a great picture, but it turns itself off seconds after powering
up. It's almost like an internal software setting which shuts the monitor
down because it doesn't like something about the video signal. I tried the
monitor with different computers and different drivers to no avail. I
opened up the monitor but I don't know what to look for. Anyone seen this
problem before?

Thanks,

Sounds like the PSU protection circuit is shutting down.
