I have an Optoma H76, that is over 6 years old now, but only has about 2400 hours on it. The projectors itself has been a brick, totally reliable. I have had one odd issue happen twice. It lost the DDC data and my computer failed to see it on the DVI port. It still worked fine on a Dish network box, but would not work on a BLu Ray player. I had to ship it back to Optoma, and for just the cost of shipping it, they did reload the rom withthe DDC data and it worked fine. After it happened a second time, they only charged me like $40 and the dud a full internal cleaning and updated the firmware and it now reports it is an H77, but I don't think I got any of the contrast improvement.
Main reason I am writing... I am in need of a lamp. I am about to order a factory Optoma at about $375 which is pretty steep considering I can pick up a brighter 1080P projector for under $1000 now, but the picture on the H76 is wonderful, pixel count is certainly not the only spec when it comes to picture quality, this 720P looks so good, and it displays my PC at 120 FPS in full 720P resolution. I did buy a pair of copy cat lamp assemblies a while back at just $185 each, but they both failed in very short order. The supplier took them back and gave a full refund. Has anyone else tried a gneric lamp and had good luck?? The first bulb had a dual failure, the lead on the end of the bulb away from the reflector just burned off, and it went out, but when it was cooling down, the UV filter shattered. The second lamp ran a full day, but when I turned it on the second time the light was crap, and when I pulled it out, the UV filter on that one was shattered. My original Optoma lamp module UV filter is much thicker, and it is also fairly discolored and looks very stressed. I do not want to just put a bulb into the module because of this issue. Does anyone sell replacement UV filters??
In any case, I am very happy with my Optoma, and will be racking up the hours much faster once I have a new bulb in it. It had an easy first 3 years because I did not have much HD content, but now with my upgraded Dih Net and Blu ray, it is on several hours a day, and at over 2400 hours on the original lamp, it is making me nervouse, especially since the lamp hours have been reset, the projector thinks it only has about 300 hours now.
