Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

How do I access the color wheel on my Samsung HLP4663W?

I removed the rear panel and the lamp housing. I also slid out the electronics module to the left of the area where the color wheel hides. But I cannot figure out how to get to the color wheel. My model seems to be different from a "well documented with pictures" posting that I found that was supposedly the same model Samsung HLP4663W. I have the new color wheel in hand - just can't get there...

Thanks,
Dale

Looking from the rear of the set, the color wheel is just to the left of the lamp, underneat an aluminum heat sink. You have to remove 7 screws to get to it.

At start up TV makes siren & ratching like sounds, no picture screen dark, requires turning TV off, is this cooling fan or color wheel problem & lamp replacement or all


That could be any of them. If you can get access to an analog meter such as voltmeter, you can test power to the cooling fan, to the color wheel, and to the lamp. See if any or none are getting power.

How do I replace the "color wheel" in this T.V.? (I have new one)


First you have to remove the Optics Engine itself, Locate the lamp housing and remove the lamp, the color wheel is attached to a large grey or black heat sink looking device, with two screws holding it in place. Look for a copper colored flex cable, and a small three wire plug connection to a Aluminum container. Trace these wires form the container which is by the way called the DMD Module. Tracing the wires will lead you directly to the color wheel assembly. Remove tthe two screws holding the color wheel in place and lift up gently, their is also a rubber seal around the color whee housing that needs to be replaced also but should come with the new wheel.

Replaced lamp & color wheel, no picture


Check your old lamp. Do you remember what its condition was like. If the tube inside the lamp was shattered into a thousand pieces that is a sign of ballast problems and that is where you should start to look. After all the ballast is what runs your lamp.

My DLP TV wont turn on.


As part of the power up sequence on the Samsung HLP-4336W the lamp isn't turned until timing pulses are detected from the color wheel. The color wheel motor is powered through the flat brown four conductor ribbon cable and the timing pulses are detected over the the three conductor ribbon table.

Samsung HLP4663W color wheel replacement


When I removed the jumper wire the screen color problems I experienced after changing the color wheel were fixed completely. I did not need to reset the CCA values (which came with my color wheel, on a separate sticker). If you have a black bracket blocking access to the jumper wire, as I did, you can access the jumper wire by removing the fan shown just to the left of the yellow and white sticker; there are two screws attaching the fan to the chassis below it. Next, remove the two screws that hold the silver clamshell (the housing for the circuit board) halves together. These screws are right behind where the fan just was, on either side of the protruding fins. They each have a spring under the screw head. You can then pull the visible half of the silver housing forward (with the bracket attached). You will then have access to the entire circuit board. Look for CN810 - it is located right behind where that bracket just was when it was all put together. Pull the tiny black plastic part (that has the jumper wire) off of the pins. Then reassemble the housing and put the fan back on.
