Are their any other symptoms of an aging DLP lamp other than reduced
brightness and possibly colour temperature?

I've had a Mits 73" for four years now, the 1st bulb that went out seemed to
produce a "gassy" picture for about a day and half before failing
completely. The brightness was reduced (although not much) but there was
sort of a fog on bright colored objects.

The second bulb didn't do that but there was a hint something was going
wrong for a couple weeks, it tended to have a light strobe effect in the
background, very noticable when the set was first turned on.

The 3rd bulb didn't show any symptoms, just didn't work anymore.

If you have a Mits and are getting that halo effect (sort a ring around
bright colored object) it's probably the light engine. I've had that
replaced also.

Hasn't been the most reliable set by a long shot. Next failure besides the
lamp it's getting **** canned.
