I purchased a Sharp 66FW-53H 28" Widescreen TV. But when the TV or video is showing a scene set in a low light situation. The TV seems to have trouble controlling the brightness of the picure. You get this effect that looks like someone sliding the brigtness control up and down in a attemt to find the best picture ! It's very annoying. It looks alittle like the macrovision effect, only not as bad. I have a engineer coming out sometime soon ? But I would just like to hear if anyone else has had this problem, and if they managed to fix it ? Thanks.
