RCA M50WH72S YX1 Projection TV with lamp problems

We have a RCA M50WH72S YX1 Projection TV. Lately it has been making a loud buzzing sound while playing. This weekend it took much longer to come on than usual, we use the cool bulb setting to extend the life of the tube. It gradually got brighter and brighter. When it reached about 3/4 of regular brightness there was a clicking sound in the set and the lamp went out. After a span of time that seemed to be a long time but the wife says was about 3-4 minutes, the screen relighted and it was fine. But now every time the set is turned on it does this and seems to be getting longer. Oh, the set has a RCA number 270414 tube in it. Any ideas?

SOURCE: WHINING SOUND

More likely it is the color wheel this set uses---it is located inside the optical engine---part number for it:

267888This part is no longer available from RCA but is available on several sites on the internet (google the part number)

The wheel will when going bad sometimes make a fan like noise or even a high pitched whine.

Check out the sites on the net that sell this for price and decide if you want to attempt to replace it or if you have to have a shop do it for you.

Let me know if you have any questions or need advice.

REGARDS, SD TECH

SOURCE: is there a led replacement bulb for the rca

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

Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Sounds like the color wheel or lamp I would check the lamp first to insure thats its not broken as they can make a pop when they fail sometime (Breaking) then I would check the color wheel you will be able to tell if the color wheel arear has the noise coming from it. If you need more assistance let me know.

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.

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.
