Samsung DLP "Grinding" Noise
|
New member Username: JpeldredPost Number: 1 Registered: Jul-06 | I have a samsung HL-R4266W. I got it in January. Its been great until the other day. I have a motorola DVR box, and occasionally hard drive hits/spins rather loudly. I thought this was happening the other day, but when I turned off the motorola, I realized it was the TV. I'm sort of a novice (this is my first rear projection TV), but after reading the posts here and other places, I took the back panels off, checked the bulb, looked at the fans, cleaned everything out etc. I taped the kill switch in place so I could power the machine up, and I still heard the noise. It really is that hard drive grinding noise - picture your PC when its doing a lot of work or is hot. What I noticed was when I stopped the lamp fan, the noise stops. But the noise doesn't necessarily sounds like its coming from the lamp fan, which is strange. Also, when I spin the lamp fan with my hand with the power off, there is no noise at all. After reading some additional posts today, I wonder if its the color wheel. I don't know where that is yet, but it seems like a possibility. Anyone have any ideas? The TV works fine but for the obnoxious noise. Here's the kicker. I don't have a warranty or service plan because I won the TV in a contest. As cool as that is, I signed all sorts of agreements that the TV was "as-is," so I have no recourse other than coming out of pocket and what I can figure out. Including the taxes I paid on the TV and this little issue, I could have bought the same model with a service plan at BB or CC for the same amount of money. Any help or advice would be greatly appreciated! Thanks. JP |

The filament doesn't necessarily break, like you tell if a lightbulb is bad. As for the grinding sound, could be the color wheel's bearings. Mine went and sounded more like a high pitched buzz than a grind. But the only two moving parts in there are the fan and the color wheel. I just changed my color wheel. See here for some pictues of the inside of the set. It may help you figure out what's going on. samsung dlp color wheel |
