RCA DLP television lamp problems

I was told to take the lamp out and shake it alittle, I have taken it out, but not sure if taking it out and handling it would be the definition of shaking it alittle, what would be the purpose for shaking it, to see if its bad?, or to shake it into submission, please explain for me.

Yhere is no reason to shake the tube...either they are good or bad and it sounds like what you are dealing with is a bad tube

Our RCA DLP has a loud hum when it is turned on, but goes away when it warms up. What is goint out?


It's' just the lamp warming up. It usually takes about 30 seconds for a DLP to start up. This is nothing to worry about.

I have an RCA DLP tv model HP50LPW52. the sound was there with no picture. since it is 5 years old I replaced the lamp for the first time. got it all hooked up, turned it on and the tv slowly came on....


That is your Color Wheel that is bad. I wish you would have posted the problem before buying a lamp. I would have told you to treat yourself to a new set instead of putting good money into a DLP set that is 5 years old.

The picture is not bright in a light-filled room. Will a change of DLP lamp help? Are there different lamps that will improve picture quality?


Yes.Depend how old is ur DLP tv,the Projection Lamp only a light source,mostly depended on the Light projection Engine itself.Get the original RCA DLP lamp or same lamp model now inside the tv,will help and work best for ur tv.Just don't get generic DLP tvs lamp,it cheaper poorer quality.

Samsung DLP HL-P5063W. . .no lamp!


Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.

Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.

RCA HD61LPW42 - no picture


I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

Good Day;

You may have a bad lamp not a loose one, take lamp out of TV and shake it a little and reinstall. If no fixya get new lamp and possible ballast. Good Luck, big IRISH.

RCA 50" dlp lamp dead?


There are many different problems with RCA televisions. One could be a color wheel. Another could be a bad ballast. www.Lamp-Replacement.com has a guide and solutions for your RCA lamp 265866 or 270414. The problem is most likely a bad ballast, which is supposed to pre-charge your lamp and ignite it. If you aren't even getting to that stage, you can trace the problem to another component or power supply.

Samsung DLP HL-P5063W. . .no lamp!


You will need to have it diagnosed if you do not have the service manual, or the knowledge of how these circuits work. I can tell you to replace this or that but it would be a guess! You need to start measuring the voltages on the ballast circuit, as I have seen door switches, fan sensors, heat sensors cause all of your symptoms as well. Good Luck
