SOURCE: Color is bad after installing color wheel in samsung dlp tv

Most times color does not to be reset. If you have a very ugly green or blue picture, then you did not pull the jumper on the dm board. This jumper must be removed when a bering type color wheel has be replaced with a new airless bering color wheel.

SOURCE: Picture Problem!!!!

Sounds like the backlight isn't working.

Can you see a very faint picture? It might be so faint that you can only see it in certain lighting conditions.

Backlight problems are usualy caused by a faulty inverter board. I think you'll need to contact Dell as they can be funny about supplying spare parts.

If you can get a picture of the inverter board and post it, I might be able to locate a pattern board for you. The Inverter board has several flat transformers on it.

Be carefull, that board has some high voltages on it. Dont plug the set in while you have the back off.

Hope this helps

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.

Samsung HLP5085W DLP - lamp replaced about 7 months ago. I powered up TV and got strange colors with flickering picture. Turned unit off and triangle symbol appears with lamp showing - needs replacement....


Strange colors and flickering picture symptom shows problem with color wheel and/or dmd board.
Lamp is only light source in dlp tv and it has nothing with colors or picture flicker.
TV goes to protection mode because of some internal problem as mentioned above.
If you wish to repair tv by yourself then you should have service manual copy in hand and that can be downloaded from HERE for small fee.
Hope these info will help you.
Thanks.

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

Missing Color.


the color wheel may spin but if you hear noise when it spins it's bad. the jumper is used when replacing one type of color wheel for a nother type. so donot remove jumper unless you've replaced the color wheel and the picture is bad. if the color wheel is good replace the DMD board. if the DMD is not available replace the optical engine.
