I purchased a Sony STR-DG910 last last year and so far so good...except this past weekend when I watch cable (via HDMI) the sound and picture go blank for a split second every few minutes. It's like it resets the video and decoder (sound). I've disconnected the cable and ran straight from the cable box to the tv (Toshiba 47hl167) and the problem disappears. I watch bluray movies via receiver through an HDMI cable and xbox360 the same way and do not get the problem, it's only when watching cable. Anyone know how to fix this or what could be happening?
