I've extensively perused this and other forums and feel a "kinship" with others who spent a good deal of money on a Samsung DLP in the early years (2006 - 8025 hours on the lamp now) only to have it go south in a relatively short period of time.
What I can't figure out right now, based on what I've seen here and elsewhere is if my problem is caused by the color wheel (it isn't making any noise) or if it is the LE failing. It goes away with a solid bang on the base. Since only two fans and a color wheel comprise the moving parts on this unit, they seem suspect. But, it could also be a bad ground or something similar on the LE.
I found this video at youtube from somone else that is the exact same model, and exact same problem, I'm having. No, been having on and off for about 18 months, along with the "on and off" problem that cleaning has not seemed to help, nor has the door latch repair. But the "on and off" is so intermittent as to have us ignoring it most of the time.http://picasaweb.google.com/lh/photo...mfnejew7diRCMc
Those of you with experience, please check out the video and opine as to whether this is the color wheel not keeping up to speed or the LE. (forgive the quote marks, but I'm new and can't post URLs - yet)
If it is the former, then I'll attempt the replacement. If it is the later, is there anyone who wants a good deal on a four your old, 42" Samsung DLP? ;-]
