Question about Samsung HLP4663W 46" Rear Projection HDTV
Loud noises from TV for last couple of months. When it first was turned on it was really loud but as it warmed up the noise stopped. They a month ago the buzzing noise continued the whole time the TV was on. When turning TV off the noise would take 10 seconds to stop.
Is this the Color Wheel or Lamp? If the color wheel goes out does it tell the TV not to turn on at all?
Assuming the noise is a high-pitched whine, then yes, it is the color wheel. If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync. The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or partstore.com (among other places) and replace it yourself, if you are so inclined.
