    it is a Samsung DLP rear projection. Model HLP5063WX/XAA.



    The unit was 3 years old this past February. The color wheel is not making any noise, an increasing in pitch squeal usually means the color wheel is shot. The bulb has lasted far longer than I thought, nearly 9,000 hours. Thos are the only two moving parts. I was wondering if the IC chips were toast but thought I'd see what others knew before jumpin the case.

I have a Mitsubishi 65" dlp TV and the picture is green and yellow with no reds or magenta's so would that mean i need a new bulb or does it have something to do with the color wheel


It means that the color wheel or it's encoder is not properly syncing with the controller. It is therefore blanking the DLP chip on the red and blue sections of the color wheel. Clean the color wheel motor and encoder disk, lubricate the motor. This should correct the problem. There may be dirt in the opto-coupler that is reading the color wheel. Be sure to clean it with a vacuum and small brush. Regards.

Wavy line on a DLP SAMSUNG 65 INCH PROJECTION TV


Bulb does not do anything but project white light. Wavy lines are a digital board problem. You should have a tech look at it.

your set is not a DLP its a traditional rear projection tv set and has three picture tubes
there is not a bulb or color wheel in this model
if its dead ? you would need to check the power supply first to see if you have the proper voltages . the trouble shoot the rest of the circuits to see what is shutting it down . convergence circuit failure is always a good suspect in these sets

Samsung DLP HLN5065W tv Black & White Picture


Yes,the problem is the colors wheel it dead.That one of the cause by the colors wheel,other are alots of squiling noises and making very loud buzzing sound.The cooling fan that u think is overheating,does it stop sometimes,when the tv is still on?Yes,than replaced it also,no than it still ok.Just hire the tv repairman,the parts he'll take care of it,don't order the parts,u might get the wrong parts or different sizes,that will not fit in ur tv.

I have a 1994 zenith big screen the picture is showing really dar


It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

Wavy lines on the screen and a high pitch sound sometimes.


If you have a Dlp it might be the color wheel.The color wheel is in charge of creating the colors and when it's bad you'll hear humming,buzzing,whirling sounds.

Red wavy lines at top of screen.


Rear projection t.v.s work differently than most. They have threw lights that throw the picture onto the screen, instead of having a color tube that is in a traditional television. It would be my suggestion to bring it to a Qaulified T.V. professional to have watever bulb is bad replaced. odds are it will either the blue or the green(hard to remember exactly but i think its a green one lol) and not the red.

Color problem + power problem


Since you say bulb, i will assume that this is a dlp projection set. Blurry color on a dlp usually means that dust has gotten into the optics assembly or that it has settled on the mirror. as for the cutting off periodically that could be the lamp (more often than not) or it could be an intermittant lamp thermistor which monitors the lamp tempature. If this is a tube projection set then in mitsubishi units this usually means that one of the projection tubes is weak and needs to be replaced. Hope this helps.
