With audio and no video for a rear projection TV, look at the lamp. Failure of this part is common.
Does the light on the front flash ? Count the number of times it is flashing. Error code.

I have the m50wh72s rca dlp....and will be changing my bulb with thanks to this site!.....but what about the colorwheel?...is it easy to change ?....and is it exspensive to buy?


The color wheel if used may no longer be available from RCA. With the exact model number GOOGLE the model number with the words COLOR WHEEL after it and if I remember some of the wheels were rather expensive.

Let me know if you have questions.

RCA M50WH72S Replaced bulb and ballast. TV comes on with good video for about 5 seconds, then off with good audio, front power light blinks 5 times. After a few minutes the video comes back on and repeats...


Check capacitors cp624, cp647 1000uf@35v each. They are in the power supply. Can be seen with bulge on the top. Seems to be a common problem with this model RCA.

Need color wheel


Unfortunately, the color wheel for this model has been discontinued by the manufacturer. So you would have to check every distributor to see if they have any left in stock. Part # is 271917. Here's a link so you can see this part's current NLA status and get an idea of pricing:
