RCA Scenium HDLP50W151YX1, Color Wheel

merled · 2006-12-16, 08:46 AM

Merry Christmas:
I have this RCA unit and just recently purchased a Sony Bravia LCD for Christmas.
I am wanting to sell the RCA, but have noticed a Hamster wheel cage sound. It is noticed when the unit is muted and is pretty annoying. I ask a person that has some experience with TV repair and he said the noise is coming from the color wheel and that is is most likely going out. He guessed the cost to be $300.00 and another $300.00 to put it in. I have checked the internet and found one location only that has the wheel for $199.00. (Part no: 212184.
My question is: Would it be possible for me to install this myself. I am very mechanical, but I do not know if this is something that takes special tools etc. The unit will be three years old in Feb 07. Thanks, merled

I am in the same situation. I have a RCA HD61LPW42 that uses the same model color wheel. I intend to replace it myself as well. I have seen a website where the color wheel of a samsung is replaced, and is well documented with photos and descriptions. It will serve as a guide for the RCA. Its all the same technology. High pressure light source, shines through color wheel, bounces off "it's the mirrors" micro chip, hits screen. I'm game. (yikez)

You can see the color wheel when you replace the lamp. Remove the lamp housing and look down into the aparatus that the light was shining into. You'll see what looks to be transparent and "colored". That is the color wheel. It spins at something like 9000 rpm and colors the light hitting the DLP chip with primary colors which are then mixed to create millions of different colors.

An overly simplified description is that if any given pixel in the signal calls for you to see, say blue, then the DLP chip flashes a micro-mirror at the screen while the blue portion of the color wheel spins by several times each second. If the pixel should be purple, then it flashes a combination of red and blue, and you percive purple. Millions of micro-mirrors equals millions of pixels, and voi'la - a picture.

If you havent already stumbled across the website I was refering to (or one like it)...here is a link.

Tonight I came home and the loud noise (of the bearings going out on the color wheel) was gone, and instead of a great picture, I have weird colors and that jump around, I can see the images, but the color is all over the place, and is in veery high contrast.

I got behind the set and can hear the color wheel spinning, but the noise is 1/10 of what it was. I can only assume the wheel has finally killed its bearings and is spinning either slowly, or out of sinc with the mirrors.

Did I loose my picture and the sound of the color wheel bearings at the same time, and they are not related? I think not. I hope I am right, I am ordering the color wheel tomorrow.

Gvinson,
What a wealth of information. Thanks a whole heap, I will order the color wheel this weekend from the same site you listed. Actually, it was the only place I found it, $199.95.
I do appreciate your time.

I use the 267888 Color Wheel and I started having the the loud whining noise, and I did my research and determined it was the color wheel, I have found the Delta motor for replacement, but I drop the lens any Idea what the part number is?

Where did you find the # for the motor of the color wheel, where can it be purchased? Been told there are no replacement parts for that. I have a new 267888 color wheel that no an exact match for my tv I could sell. I needed 212184 color wheel, was given the other one by mistake.

I've read the posts, and removed the color wheel, lubricated it with 3in1 oil and reassembled. It was quieter but still hums. Tried more oil and it still hummed but with the addition of the bulb going out also. At 3 to 450.00 to repair this dlp for parts alone, this tv is done. For anyone wanting to try it for themselves, remove front panel, then screen, then one cover with 2 screws and easy access to the color wheel. I figured a 4 dollar fix with sewing machine oil was worth a try but nothing more. A six year old tv with only one bulb replacement for a scenium was pretty good I'm told but it is now time to move on to LCD I think.
