Yes, heat may well be a factor. I'd imagine that a repair would cost a few hundred bucks (they'd probably start by replacing the light-engine). So it might be wiser to upgrade, especially considering the current prices on LCD's. I went for a Sony XBR 1080p LCDTV, and I'm SO glad that I did. It is so much nicer than the DLP. I passed the DLP on to my in-laws, and it's still working well for them on the original lamp.
Thanks Gary. That is what I am thinking. I will have it looked at to find out the possible cost. I have already started looking at the new LCDs. I have a Vizio 32 inch in the bedroom that has a better picture than my DLP had, so I may use this time to upgrade.
Well Gary I found out the repair was more than I was willing to spend, so I upgraded to a Vizio VF552XVT and was amazed at how much better the picture is. I haven't really looked at TVs since I bought the DLP 4+ years ago. The repair guy is even going to buy my TV for parts .
I Just put another $120 into my 5674 -- definitely the last time. I replaced the color wheel myself for the 2nd time after it shattered. Took me about 30 minutes total time this time a great improvement over three hours last time. I replaced the bulb last May.
This time the color wheel was my fault -- I was sanding new sheetrock seams in the room with the set while it was on -- the fine grit in the air got pulled into the set and it didn't have a chance.
