Other than changing lamps, i'm wondering how long the average projector will last before having to have some kind of expensive repair.
I have just read in another thread about Sony replacing an optical block in a projector, and having it cost $3500! This is the first i have read about this, and haven't heard of it in any other thread.
I also believe i've heard that DLP projectors need new color wheels occasionally.
So how long have users used their projectors without issue (besides lamp/color wheel replacement)?
