Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

Our Samsung HLP4663WX/XAA has audio but no video - is it the lamp

For the last few weeks it would make a loud whining noise when it powered on. Now it does not make the whining noise. It has audio but shows no picture. Could it be the lamp? If so, is it difficult to replace?

HLP4663wx/xaa Fan or Color wheel making noise? I first noticed it within the last week making noise when turning the set off. Now it's continuous. Could hear it slowing down on power off, constant...


A fan like noise is 98% of the time the color wheel.

Wheel turns at over 12,000 rpm and common failure is "fan like sound or even grinding sound".

When these sets first came out if the high pitched sound started women who have better hearing in that range usually hear it first.

If wheel really fails it will shatter and set will not come on----a grinding sound may be noticed just before total failure.

Samsung HLP4663WX/XAA picture went out, started making strange noise, all lights on power button came on.


Sounds likea bad color wheel to me, or possibly a lamp has blown. If the noise is a humming sound--it is the CW--if you hear a "sound like a sizzle, for a few seconds and then normal, and this repeats a few times--the lamp has blown.
