Problem for RCA HD50LPW42 50 in. Rear Projection HDTV Television
Need info on fan for RCA HD50LPW42 TV
By Bob Headrick on Oct 14, 2008
I have an RCA HD50LPW42 projection TV that sounds like the fan bearings are failing - noisy during running and a loud noise when it shuts down. Before I open things up and start poking around I would like information on what to expect - is this a standard 100mm or 120mm muffin fan or is it "special"? I have not been able to find any service info online, I would appreciate any link to a suitable replacement fan and/or a service manual.
I will rate responses appropriately.
Regards,
Bob Headrick

- I could google for the fan if I knew the spec's. Do you have a part number or any other information that would narrow things down? I would like to get the fan before I open it up....Regards,

- I have the same problem. it started happening a while back then the bulb went out. I replaced the bulb and it was fine, for a while. Now it is making the "saw" sound again, but worse and more intense. I took the lower back covering off and completely dusted it. I figured the noise was coming from dust build up nicking the fan wings, but I was wrong. I narrowed the noise down to the fan that is to the left of the bulb. This fan is concealed inside of a gray box. Before replacing the second fan I am going to dig a bit further into it. Any suggestions?JP- jpstallion4

Thats a DLP and those fans are noisy. Most of those fans are special and I don't think I can recommend a dealer but you can Google Electronic Parts and pick one. They will need the Model Numbers as well as the Chassis number. There is no guarentee it will be any quiter for very long. You might check with some local TV shops and see if any of them have a good used one. DLP's go bad all the time and many times it's the light engine and the fans are realitively new.
