Question about Samsung HLN4365W 43" Rear Projection HDTV-Ready Television
I have a Samsung HL-R5688w. Every once in a while I notice the color in background scenes starts to look patchy and mottled. I don't see any problem with things in the foreground. For instance people in the foreground look OK but if they are standing in front of a wall, the color on the wall starts to look patchy. It's distracting. I was wondering if this was a color wheel issue even thouhg there is not audible screeching that I've read about. Any ideas?
Its possible that the speed of the color wheel motor is starting to drift from the normal range. Its also possible that the DMD board or digital P.C.B. are the culprit.
Contact an authorized Samsung service center, ask them to try to reset the wheel speed using the index delay parameter in the service menu.
They should be able to eliminate the problem or at least identify it as a bad color wheel or otherwise.
