Question about Sharp 56DR650 56" Rear Projection HDTV

1 Answer

Picture fine for 10min.-then flickers(clicking sound)& then colors gone yellow

Our Sharp DLP TV is about 2 years old. Plays fine for about 10-20min. then Colors flash and a clicking noise comes from the back of the set. After it stops the colors are all washed out-looks like a tie-died Tshirt with splothes of clouds in the background. Is there any way to repair this? It doesn't seem to be a bulb problem(no warning errors)-any help is appreciated!

Looks like it's a color wheel problem-found a cleaning walkthru online, but it doesn't get rid of the loud hum form the CW motor. Also, it is thermal related-when the colors went out I placed a fan next to the color wheel and everything went back to normal. Several design flaws here and for $3000 these companies should do better-severe problems after a couple years is not acceptable.

I have a Vivitek RP51HD41-A TV. The TV keeps turning off and on. The color and sound is fine. I have replaced the lamp and this has not fixed the problem.


If its a DLP it may have a color wheel which could be your problem (the colors will change etc)

Color wheels move at high speed and if slow down set will shut down.

The wheel if there will face the lamp. If often if failing will make a high pitched whine or a fan like sound.

Hi I have a Samsung HLN467W, a 46" DLP TV. And after 50-60 minutes, it starts to flicker white, like lightning flashes. But the whole screen is not blank white, it's more like the images are...


Hi,
It seems color wheel problem in your tv that gets problem after some time and you hear high pitch noise along with picture flicker.
Color wheel need to be replaced to solve this issue. Required color wheel is available with PartStore.com (click to view image of part and price info) and it is job of qualified tv repairman because light engine will take apart for that.
Hope these info will help you.
Thanks.

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.

DLP TV starts to loose picture after 1 - 1/2 hours of use


This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. see which inputs have the problem to narrow it down. if only some inputs, suspect analog board. if everything flickers(all inputs and menu), suspect the dmd or engine. you can see the lamp shine out the back. if the lamp is flickering, suspect lamp or ballast.

Noise from Samsung rear projection DLP HD TV.


this noise is an indication of a bad color wheel. aa dlp uses a mechanical motor to spin a coloered segment disk. this turn the white light of the lamp into your colors of pictures. Now anything that moves will eventally break. the flickering is also an indication of a color wheel going bad. eventally this will cause the set to shut down. Color wheels can be replaced. i dont know your model so i am not sure of the exact replacement procedure. at my shop we charge average 250 for such a repair
