Question about RCA HDLP50W151 50" Rear Projection HDTV

Start-up on RCA HDtvDLP M50WH72SYX12

I have a RCA M50WH72SYX12.For the last 2 days when you turn it on it goes thru a sequence of turning off and on with the green light flashing 5 times . Twice it didn't turn on at all. Now this afternoon it's on after going thru the same sequence. My manual says the bulb needs to be replaced. But I can't find a model # for the bulb. I tried the 800# on my paperwork and was told to leave the set on for 24 straight hours and then turn it off. Then she said to turn it back on to see if there was still a problem. She wouldn't give me a bulb # untill I try this. Isn't there a possible danger of heat buildup or the unit catching on fire? Is this some sort of reset?

    Ref:RCA Mdl# M50WH72SYX12 Delayed starting going thru sequence. Sorry, I havn't been on here in a while. We did get a new bulb. That wasn't the problem. Called 800# agin and asked for repair facility. Took it in and they said unit needs a Light Engine. Estimate of $1,076.70. Needless to say I went back and picked up my set and now am watching it. I'll let it keep going thru the sequence as long as it keeps working. Heck Thats about what I paid for it brand new. Needless I will be getting in touch with RCA. Unit is only 3 years old. Can anyone help. Have you ever heard of this.

I have an RCA M50WH72syx12, 50" DLP.


Yeah could be expensive if it isn't the lamp.
Mind you could be a little easier, might just be a fuse on the video relay. If you are confident in being able to open it up, check the relay that runs from the video input to the power capacitors and there should be a small fuse along that circuit.
If the fuse has a broken capsule then you may just be in luck. Failing finding a broken fuse, then I would agree with you on the bulb. But check the blub for any markings or cracks because they usually only make noise when the vacuum fails.
Hope this helps and good luck mate! :D

It randomly turns of by itself and sometimes doesn't turn back on for awhile. The last time it did it I unplugged it and left it alone for about a day or so. When i turned it on it worked a full day...

The master convergence needs to be set in the service menu. You can't do this yourself.. you'll need a technician.
