Hi, I have a Sony video projector VPL-HS1 that is behaving badly. After powering up it works for about 30 seconds. Then the lamp is switched off, the yellow Lamp/Cover goes on and the green power LED blinks; first fast, then slower and finally the thing switches to standby.
I did clean the air filter.
The fans come on first and then even slow down a bit.
There are tiny cracks in the outer lamp glass near the small end. Yet the small bulb inside is intact and it works with normal brightness.
I know next to nothing about video projectors. It doesn't make sense to me to indicate lamp error when it actually works. Are there parameters monitored that I am not aware off? Or could just the monitoring circuitry be broken?
Cheers
Tony
