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.

Pretty sure it the bulb as most are rated at 2000 hours; but also check for full air flow - clean filters etc. Bulbs can run hotter as they age, so air flow is more important, because there is an inside heat sensor that will shut the machine down.
you may have to reset the lamp hour meter to get it to work, put the projector on stanby and press the remote buttons, reset - back - forward - reset, (this is the code for a vpl hs20 projector it may be slighty different for your model)
There are a bunch of steps I could walk you through to detect the projector and then set the correct resolution and color depth. But it will be easier to have you just attach the projector and then restart the laptop so that the system will attempt to re-detect the second display automatically.
Then just right click the desktop and select properties. Go under display properties, settings, and enable the second screen (2) as either a cloned or extended display.
These instructions are for a Sony Cineza VPL HS3, but may be the same for the HS3.
1st thing to check - is the cover properly/completely closed - this can stop the projector from working.
Connect the power and set the projector to standby mode.
Press these buttons on the remote control in this order, for less than 5 seconds each.
Reset - Left Arrow - Right Arrow - Enter
This is required, to reset the lamp timer.
Also, something I found interesting from the internet - lamp life isn't
when the bulb dies, but when a bulb has lost 10% of its brightness - so
you might well be able to reset the timer and get much more use from
the bulb - the image just wont be as bright.
I know this post is 3yrs old, but wanted to add a couple things. I have the VPL-HS20, you can take the filter out and blow it out with air can duster every so often. I bought a new one and they are over $30.00.. Also buy the correct bulb LMP-H180 3000hrs if you replace it. You can clean the front lens protector, Remove slide tab, hold top and bottom of lens cover assembly and give a firm 1/4 twist clockwise, then pull out. You can clean it with glass cleaner cloth.
