Major Problem with Epson 1080 UB

Serendipity

Right after I got everything set up...

You power on the projector, use it for 3-4 minutes, then the projector seems "locked up" and displays a blue image with black lines and other scrambled crap in the picture.

What could cause this? I can't see anything, except for blue and black lines that are like ///////////////////////////////////\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\///////////////////////////////////\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\///////////////////////////////////\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\///////////////////////////////////\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
on the screen.

The projector is "frozen" too, you can't do anything except power it off and then on again with the I/O switch on the back. This is bad because it's not going through the cool down period either.

After tinkering around with the projector, I'm now in "High Altitude Mode" and this seems to make it work better. It's still locking up, but not as often as before and allows me to get through a 2 hour movie most of the time.
