I have a Sharp XVZ1E lcd projector. I want to replace the lamp. A friend of mine who deals in lights & stuff is fairly confident he could fit the bulb without problem (using sterile gloves), but my main concern is being able to reset the lamp usage hours. Sharp don't seem over-anxious to let people know how to do this. Can anyone here help? Returning the unit to Sharp UK is fairly impractical in my case as I'm in Ireland. I've found wildly-varying prices for the lamp too. Any help or advice to do with any of this much appreciated. -Kevin.
