Re: thomson tv

Umm you can buy my 44 thomson for spare parts.. i just bought the last sony 55 projector tv as sony will only make lcd and plasma now.,. not good for the enviroment as they use way way way more power.. than a projection tv.. but i guess global warming doesnt matter to peeps that want to hang a tv on their wall.. which is ugly a tv should look like a tv not a piece of glass...

Your color wheel is going bad, when it fails the TV colors will be way off and it will shut down. They range from $50 -$125 . Here is one for $98 for your tv.

Samsung HLN5065W 50 in. Rear Projection HDTV-Ready

With the back off of the set it will shut off. There is a lever it engages to prevent the set being operated with the back off.

The color Wheel will cause a fan like or high pitched grinding noise. I can tell you where to buy it and also there are on the internet places with written and VIDEO instructions for the replacement in most of these sets.

Put the back on and see if the set again works and still has the noise.

Thomson Scenium 52''Rear Projection TV set -

you have a laser that has gone out blue or green take the face off and see which of the colors you need you can still find lasers on ebay if you need one but it will require someone with a little expertise to replace them. if this is not for you then its time for a new TV this is probably the best option its more expensive to fix in most cases than to replace..........I hope this helps

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.

Projection tv has really loud buzz or hum

You may not see any deterioration in the picture when the color wheel begins to go bad. The noise will get louder and eventually, it will shut down or the wheel will shatter while the motor continues to spin. If that happens, you'll have a black and white picture.

If its a Samsung DLP that is mercury vapor lamp driven, its a safe bet the color wheel is going bad.

I have an RCA Scenium HDTV DLP, Model HDLP50W151. Turned it on and went through it cycle, whining sound but the screen was gray. turned it off and then on picture and there was no whining sound....

Sounds like the Color wheel on the Light engine has failed. Its a major repair. Contact Thomson at 1-866-465-7157 to find a local authorized repair center.

No picture when I turn the TV on, I do get sound

You either have a bad lamp or color wheel. You should always try the lamp first and 9 times out of 10 that is the problem. If you heard any grinding or whining sound or your unit vibrates it would be the color wheel.
