You can get these http://www.letsautomate.com/homevisionsensors.cfm?
A TV Sniffer which will detect a CRT (only) being on/off
An LED detector which you can hook up to the on/off LED on the TV/Plasma
A video detector probe.... I'm thinking you could possibly use one of
these if you configure one of your scart sockets to input/output mode -
when TV is on, there should be a video signal, and when off there
shouldn't.... don't know wether it detects abscence of signal or what so
may cause problem with outputing a still black/blue/ static screen....
check with Phil or someone
These are all listed for HomeVision, but you should be able to get them
to work with any circuit you setup.
