Ok guys, I either just noticed this today, or it just started today but it is really bothering me. For some reason my RPTV seems to flicker the brightness level at a noticable level, not that its completely distracting, but it is noticable. Ther are slight variations in the brightness level that change extremely quickly that makes the display look like its subtly "flickering". I first thought it was the video side on my receiver, but ran the connections directly to the TV and it is still there, it looks to only be visable with black levels though. Could it possibly be electrical interference from all the cables behind my audio setup? I'm at a loss. Thanks guys.
