I'm sure this is something covered elsewhere, but I must be using the wrong search terms. There's probably even an AVS forum name for it.

I've got an old Infocus X1a with 155 hours on the lamp. It's probably from '04, and we only watch DVDs on it via component. Not a dedicated room, so I've got a pull down screen and just set up the pj on movie nights (hence the smallish hours total).

Anyway, it hasn't gotten much use the last 6 months or so. Last night I broke it out and noticed the problem. The movie looked OK (a bit dim, maybe) but then I noticed a horizontal band of purple/pink straight across the middle of the screen. It was maybe 3 inches thick on a 90" throw. It appeared in the middle and then slowly moved towards the top, to be replaced by a similar band, this time greenish. The color bands are really faint, but both the wife and I noticed them. I think they only started appearing after the pj had been running for a while. I let it cool down and then put in another movie. They were gone, so I watched for 20 minutes and they started up again.

I'm wondering if the bulb is going, or the color wheel needs cleaning, or something else.
