Question about RCA HD50LPW42 50" Rear Projection HDTV

1 Answer

My RCA is screeching

My RCA HD44LPW62 makes a screeching sound when I turn it on. No picture or any other sound besides the screeching. It screeches for about 8 seconds then stops, the green light blinks 5 times then it screeches again. 2 days ago the color was all messed up then it seems to have fixed itself. Now I have nothing but screeching! I have purchased a new color wheel (part # 212184) for my RCA HD50LPW42 and am looking for instructions on how to install. Any help would be appreciated.

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 and loud screeching on RCA Scenium 50" DLP


It sounds like it is the Color Wheel. I do not think you can get the Color Wheel separate from the Optical Engine like you can with Samsung. RCA is very tight with there parts like that. Because you have to get the whole
Engine Assy, cost would be too much in my opinion to invest into it. The part cost approx 800.00 the last time I checked on one.
Good Luck,
I Hope this helped,
