Anybody getting constant picture and audo drop-outs every few moments? By that I mean the screen just goes completely black for a second or two, then comes back on. I've been on Fox News and thought it might be just the channel, but then I switched to the History Channel and the same thing. We're having a bit of sporadic thunderstorms today, but I've never seen signal drop-outs like this before. You know usually, the picture pixelates and the display goes to the satellite searching for signal screen, but these are just as I described above. But now as I type this, History Channel seems to be fairly stable. Haven't had a drop-out for about 10 minutes now.
