Hi, folks, I have a WD62927 about 6 years old. It was working last night when my wife was watching it but, of course, this AM my kids went to turn it on and it made a clicking sound and had no video. We can get audio no problem though. The sound only occurs when turning on the system and sounds almost like a fan blade hitting something or like a relay popping on and off very rapidly. It will reoccur about a minute later and keep reoccurring several times. Then the whole unit will shut down entirely. I replaced the bulb in the unit about 4 years ago, could it be the bulb again? The last time the bulb died, it did it very slowly, getting dimmer and dimmer over a few weeks. The brightness on this one was fine last night while we watched the UCLA/Stanford game. I reset the unit from the front panel hoping it would fix the problem but no joy there. Any ideas? Maybe time for a new engine? Or a new TV entirely?
