If the color wheel you replaced was the BP96-00674A, it would have come with the proper cca adjustments for that particular wheel. You must enter the service menu and reset the cca's for proper color.

What is the difference between a color wheel and a color conversion kit on a Samsung HLP4663wx


HLP4663WX is a DLP which has a color wheel. The DLPs dont have convergence circuits since there is only one light source. Projections with three CRTs have convergence which is the alignment of all three CRTs ( Picture Tubes)

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.

My tv is a samsung dlp. i have determined that


most of the time you just need to replace the color wheel; the jumper they are talking about is on the DMD board which is a metal box attached to the light engine---if the jumper needs to be removed you will have a working set but the color will look odd--usually missing blue or red---it is a small two wire plug with a jumper and can be removed with a hemostat or needle nose pliers.

If you buy the color wheel I have specific instructions that you will not find on line to avoid problems when you replace it--lots of people think they can do it until they try and fail.

if this has been helpful I would appreciate your vote here.

Hi, bearings in color wheel are about to fail, get it fixed now before the wheel shatters the prisms all over the inside of the tv which of course will then cost you more to fix, video-tek

Blinking lights


Sounds like the color wheel. Check samsungparts.com for a replacement. Check the video on youtube of a guy fixing his color wheel to see if its something you want to tackle. I changed mine... a drag, but not too awful. Ran about $100.
