I wouldn't worry much about a "new" problem beyond the bulb finally failing. Buy a new lamp with housing (they come either way, make sure you are getting the bulb with the housing) and you can replace it in less than 10 minutes. I just did mine yesterday (HL-R5667W) and it was a piece of cake. The PQ returned to the fantastic level it had been when brand new. I had 9865 hours on the bulb (which is way
more than typical.) I expected about 3500 hours max. When I calculated the hours used per day, it came out to 11 some hours ...which is correct given how I use the TV (as a radio much of the time)
I believe I got this kind of longevity from the bulb for the following reasons:
1. I never turn the TV off if it is not going to remain off for at least 4 hours.
2. The TV has always been on a UPS (large), and therefore has never been exposed to rapid on/off cycling due to power interruptions, nor has the lamp cool down period been skipped due to a power failure as the UPS runs the fan during a power failure for the required time to cool the lamp down.
The picture finally got dim enough, even after the final 3 months of running in Dynamic (torch) mode, that I decided to replace it. The lamp still works.
Based on this and my usage pattern, I can plan to replace the bulb every two years, which makes my bulb replacement cost about 5 bucks a month. Well worth it to get what looks like a brand new tv!
