HD50LPW42 making noise near lamp

I have a HD50LPW42 and the lamp went out. I replaced it and the sound and picture are fine but there is still a humming or buzzing noise coming from near the lamp. It does not seem to be the fans and they are working when they are suppose too.Does the color wheel have some kind of bearing on it?

I have a RCA HD50LPW42, the tv stopped showing the picture awhile back but the sound continued when the tv was turned on. Now the sound has gone out too. When I turn the tv on the green power light blinks...


Hi,
You may have two problems with your TV. This TV has a history of a color wheel issue, was making grinding noise? Have you ever changed the lamp?
It may be a bad color wheel and the lamp, you may want to do a visual inspection.
It is easy to replace the lamp but more likely the color wheel is the problem.
The part# for the color wheel is 212184, the part# for the lamp is 260962

Best of luck

If you replaced it with a brand new lamp then your light engine is provably bad. The only order thing you can check is your color wheel. www.interliquidparts.com

My RCA is screeching


To install the color wheel, turn off and unplug the tv, take off the lower back casing (17 star type screws), remove the lamp door, remove the lower back casing. Look just left of the lamp you will see 3 smaller star type screws near a small circuit board (which is on the color wheel), remove those screws unplug cable from color wheel, unplug other end of 2nd cable from tv circuit board (just to the upper left nearest to the color wheel.

All you have to do is install the color wheel, plug in both cables, put the back on and place the lamp door back in its position, the lamp door pushes in a lillte blue lever which allows the lamp bulb to light up.

I'm in the process of doing the same myself on my RCA same model. Where did you buy the color wheel from?

No picture, installed new lamp but it is not getting voltage


no can't check power out to high it is about 15,000 volts out put all you can do is is listen to ballast and see if you here a spark if not bad make sure you have the light door switch bypassed.

Green light On Off


You should listen for a strike noise at the lamp or ballast area, 1 strike for each cycle. A weak lamp will take more strikes to start, until one day it never starts.
