Color banding after replacing ballast/color wheel
Posted: Tue Oct 11, 2011 12:48 pm
My HLS-6767W started having the 3 flashing lights problem.
Replaced the bulb to no avail. Ordered a new ballast and color wheel and that got the TV working again. Put the old bulb back in since it didn't seem to be the problem in the first place.
Now I've noticed that dark areas have a postertization effect, or color banding. Like looking at a full color image on a 256 color desktop, for example.
Otherwise, the set looks great. Seemingly more contrast, very sharp HD image. But the color banding is driving me nuts.
Could this be related to an installation problem? Is there some setting/jumper I need to toy with? Any other clues on how I can get rid of this? I find it hard to believe that there is yet another part that needs replacement since this issue wasn't there before the flashing 3 lights problem started in the first place. Any thoughts?
Thanks!
