I've got a new Mits. 46809 and I've been noticing a subtle (sometimes not too subtle) brightness flicker. I can see it regardless of which video source I'm attached to, in fact....I can see it even better when no video source is turned on. (cable and DVD off) It seems somewhat intermittent and shows up more in darker scenes, or as I indicated, with blank screen but TV on. It's kind of like a washed out, foggy look that flickers like a candle. It really has become annoying. Does anyone have any suggestions on this? Experience with the same problem? I'm having someone come out later in the week, but before they do, I'd like to sort it out myself if I can. Thanks in advance for any input.
