Problem for Projection Televisions
Generic problem for all Projection Televisions
Turn it on and sometimes
Turn it on and sometimes it turns itself off. Can usually get it to stay on. When the set is warm the volume reduces by itself with lots of clicking noises, when it gets to zero the set changes channel by itself with more clicking noises. Cannot rectify without waiting for the TV to cool down.

tv turning off automatically
for first unplug the main power cord of the tv for couple of minutes and then reconnect it.also before reconnecting the power cord of the tv again remove all the external device wires connected at its back such as dvd player/vcr etc etc.just connect only tv wire and check out.if still the same problem then its quite possible that the capacitors and ic on the circuit board are getting short in between so the circuit is not getting completed and cutting in between so the tv starts and turns off.in this case the circuit board needs to be checked with a multimeter.the faulty and burned out component part should be detected and then should be replaced with the help of soldering iron.to make it proper.to avoid further damage i suggest you that do not on the tv again and again as it will short some more tiny components and the reparing cost will increase as per that.at present its the normal circuit short problem in the tv get it repaired before using the tv again.
