What chassis number is your set? Should be an ATC number on the rear of the set. Let me know that number as each series DLP is different for voltages

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.

No, LED light engines are different than Mercury Vapor lamp engines. They have different power supplies and different control boards.

Changing DLP bulb


there is not true schmatic to change a Dlp bulb. It should slide or twist right out of its balast and you should be able to put a new one in the same way.


Thanks

No picture good sound good lamp can change channel


I have the exact same TV and have had the exact same problem. I talked to a TV repairman who said it has to be my deflection board. I just found this out today so I am looking all over the web for a deflection board. I hope this helps! Tyson

I changed the bulb in the m50wh72s RCA DLP tv. Before I changed the bulb I had sound. Now I have no sound or picture. Any ideas? Thanks


Check that when you turn on the TV the Lamp is striking (turning on).

My thoughts are that you will have to reset the lamp hours counter to make it work, as the TV does not know that you have replaced the lamp. To do this, check the leaflet that comes with the lamp - it should explain how to reset the counter for the lamp hours.
