I've got the projector listed above (XG 110 equivalent if I remember correctly) and Curt's helped me out a few times with dead system boards.

A few days ago I had an interesting one.
Symptom: Picture at 720p got "noisy" for a few seconds. Not snowy, but picture quality degraded significantly. After a few seconds, the projector shut itself down and I think the code on the LED was F8. It did this several more times after restarting, it would run for a while and then get noisy, and then shut down.

However, after that first day of trouble, I have been unable to get it to happen again to confirm the code. I looked it up in the service manual and evidently that code can be caused by problems in the Wave board, the Conv Drive board, The D-CONV board or the C-DRIVE board. (Are conv drive and C-Drive the same board?) I looked in the schematics and noticed that C-Drive has STK modules on it, which have died in this projector in the past.

Without borrowing an oscilloscope and checking the output waveforms listed in the troubleshooting steps, I'm curious whether this sounds like a "well known" problem or whether the symptom suggests a particular one of these boards as more suspect than another...

Thanks,
Andy

Bump... problem disappeared for a week, but now it's back. The code is actually F9, so it seems more likely this is a focus board problem. When the problem occurs, the whole screen is quite out of focus, so the manual's suggestion that this is an F-DRIVE board problem (or possible A-DRIVE) seems reasonable. Sent some mail to Curt looking for swap-out availability or other troubleshooting steps...
