Question about Sony VPL-HS20 Multimedia Projector
I get no message on the screen. For some unknown reason the projector will just shut off in the middle of a movie. I can hear the fan working when the projector is running. Filter was replaced recently. I get no clue from the troubleshooting seciton of the manual, and there is no mention of an automatic shutdown circuit. I am guessing that this might be some sort of thermal shutdown, but the projector does not feel overheated when it turns off. What else could be causing this?
There is a heat sensor cutting down the power. The sensor is located on the upper side between lamp and fan and is monitoring the air temperatur. I don't know what is causing the sensor to switch - excessive heat or simply age or ... . Anyway un screwed this sensor and my problem disappeared.
Possibly a stronger fan would solve the problem too.
