Question about RCA HDLP50W151 50" Rear Projection HDTV

1 Answer

How do I know I need a Color Wheel?

I have a RCA hd50lpw62a that will give off a loud buzz/hum (sounds like a hair clipper, and is quite loud) when it is first plugged in, anytime it is on, and for a while after it is turned off. You can tell it is obviously something on a motor, something in there that is spinning. I can't find a place to get a service manual for this unit, so I am hoping someone can shed some light on this for me.

Thanks

    Thank you Slinteriors

    So I know now it is the color wheel, but can't find anywhere to buy one from, I have found a whole lot of posts about people having the same problem finding a place to buy one, but no answers. Does anyone know where I can find a color wheel for this unit, or the part number I should be looking for?

I have a rca hd50lpw62a and its slow to turn on and dim when on.


If your tv is around 2-4 yrs or used 6000-8000 hrs,never replaced the lamp before it could be time to replace it.If you hear strange noises like buzzing or humming noises it could be the color wheel which is a little disc that has a gamma of colors and spins at high rpms.When the light of the lamp goes through it creates the colors on your tv.The other most common failure is the board that powers the lamp,which is called the ballast.When its bad it will make a clicking sound or like wanting to turn on.Your part # for the lamp is 265866 and you can find it here: http://www.discount-merchant.com/RCA-265866-265919-269343-271326-270414-Lamp-p/rca-lamp-265866-26591-269343-r.htm Good luck and blessing for your house!

My RCA 52inch DLP TV has 5 blink red lights and is making a loud buzzing sound. I am pretty sure it's the color wheel, but from your experience, could this be it?


the loud buzzing could mean something is stuck in the color wheel or that it's shattered. Either way, you're going to need a new color wheel, I agree.

After I replaced the color wheel there is a loud humming sound. Is there any way to elimate that sound?


Is the sound coming from the colour wheel ??
Maybe you bent the wheel ? sounds like its not ballanced.

My Rca hd50lpw62A turns on and sounds comes on but only the light blinks and a loud whirring sound begins...


GET rid of that TV it's a piece of JUNK! I had A 50 inch dlp color wheel went than the lamp the the digital circut board went and they want $600 for a new board . Not worth fixing(if by some miracle you can find any parts) sell the parts and move far away from anything with RCA on it. My new pioneer 5010 plasma is AWESOME!! $2600 tiget direct.
