Recently, my 4DTV has been erroneosly showing a digital panel on an analog channel. Last night, when I was on G7-17 the screen displayed a digital panel and when I brought up the satellite list it showed I was on X4 even though I was on G7 (was watching Reelz). Not to mention the DCII audio and video started getting choppy several months ago. Battery was replaced a year ago and everything was fine then. Is there something I'm overlooking or is my 4D bricked? Model 922.
