Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television

1 Answer

Very noisy when turned on, then shuts down, Samsung 61 inch

It sounds like a fan running then binding up, but a visual of both fans shows no problem. Even replaced the small one! Just Replaced the bulb, because of previous bad bulb indicators on the front ,but the racket continues until the set shuts itself down in 30 seconds or so. Thanks in advance for any suggestions.

Loud noise, then shuts down after seconds , fans look ok

On U_Tube, there is a video that shows the replacement proceedure. I understand it is quite good. My neighbor used it and it went in pretty easy. If you Google the model # it should be able to give you a link to it.

If you hear the Lamp fan turn, it is probably the lamp it self that has failed. If you do not hear the lamp fan turn then the fan could be bad or binding.

That's probably the Color Wheel you are hearing. When you turn the set on the color wheel has to run, one of the several things that has to happen for the set to come on. The color wheel sends a signal back to the control circuit to tell it it's running. If these sets fail to light the lamp they will shut off and try again, that's why you hear the color wheel start then wind down then start again. The set should try three times before it decides it's not going to be able to turn on.

One way you can tell the difference in the fan sound and color wheel sound is if you can get the set on, let it run for a little while so it gets warm, then when you turn it off the color wheel will start winding down but the fans will continue to run for a minute or two.
