I have to agree with techman. OSD and remote are controlled on main board, but yellow spots usually originate in the light engine (on dmd board). The only other thing you can try is to unplug set from power source at the outlet. Sometimes strange problems will go away at reset. Otherwise I would probably start with digital pcb. Good luck.

Yeah, sounds like there's a problem with the Scaler and the DMD board. Remote control functions are programmed into the system control section of the Scaler. The OSD generator is also found in the system control section. The patches indicate bad pixels in the DMD module inside the Light Engine.

Sounds like you have two seperate problems. First one may be a system control issue, or power supply issue, the second one sounds like a bad light engine and that is expensive! Good Luck!

Sounds like you may need a new lamp according to my Samsung DLP manual for a HLR4667W.

"Why do I need to replace the lamp?
The lamp used in a DLP TV has a limited lifespan. For the best screen quality it needs to be
replaced periodically. After replacing the lamp, the screen quality will be bright and clear as new."

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

I have a problem with samsung sp 50 l7h a 50 inch dlp tv


I can see you have a Samsung TV, well the issue seems to be your ballast which doesn't have enough voltage to keep on with your lamp. This is why you keep losing the picture every certain amount of minutes. The thing with Samsung Tv's is that they have issues with the ballast and the color wheel, they tend to go bad pretty fast.

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
