Does anyone know where I might find an OEM replacement lamp for my Mitsubishi HC4000? I checked AVS, B&H, Provantage, and Newegg with no luck. I am NOT looking for an OEM bulb (OSRAM) in non-OEM housing. I already tried that route and returned 2 duds. The first one wouldn't fire up on startup after 6 hours of use. The second one is producing a high temperature warning light after about 8 hours. My original OEM bulb works fine with 4000 hrs, although it's gotten dim, so it must be the replacement lamps. I'm tired of trying to save a buck and am willing to pay for the OEM lamp in Mitsu packaging! Any tips on where I can find one are appreciated.
