Location: Houston, TX Problem: Me and my family pretty much tune to ABC, which is on channel 13, and for some inexplicable reason, the screen is basically glitching up, while displaying the remnants of the previous channel last tuned. This happens on all my receivers. However, when tuning to another channel, it does not experience that glitch whatsoever. Question: Would this be an indication that my box is giving up? I do apologize in advance if this post is not up to par.
