Projector Lamp Life Ratings

[RelievedSimplet]

I purchased a Mitsubishi HD1000U back in December. The lamps rating is 3000 hours on Low brightness which is what I've run it at. Now I know since it's rated at 3000 hours, you should replace it at that point. But I've recently been told by a fellow owner that you can just reset the counter in the projector by holding a few buttons and it'll keep going past the 3000 hours. What are the risks of doing this? Will it just die completely one day or could it lead to worse problems such as damaging something? Basically I'm just wondering what the possible problems of running a lamp to 3500 or 4000 hours would be? Any input is appreciated.
Thanks,

Redbudstar,
Your replies read like advertising copy and this is the second time you've posted about this chinese large screen technology in a thread that is totally unrelated to it.

A bulb rating typically means the time to half-brightness - meaning at that point the image would be half as bright as it would be when new. Even if you mess with the counter, it doesn't change the fact that the bulb has worn. All it would do is prolong the time before the projector shuts itself off (IF it uses its 'life' counter to determine when it is approaching the end of its service life).

So...you could use the hack to change the projector's idea of how old the bulb is but it won't change the fact that the bulb is nearing the end of its useful life. Some people may not even notice an image that is half as bright as it was when the bulb was new so I don' think there are any consequences to 'lying' to the projector about the life of the bulb as long as the user is ok with the image quality.

It depends on how often you strike the lamp and how long you run it everytime you use it, I use my PJ every weekend for 3 days at around 10-12 hours and the bulb is still bright at 1540 hours at the half way point.
so I think it depends on the usage the amount of hours you use it and keeping the filter clean so overheating won't affect it because good ventalation is a big plus.
