I don't know if this is applicable, but I had a heck of a time with my cable input through Denon AVR-1613 causing the display to blank out, and I went through swapping cables etc. to try and isolate the problem. Eventually, I narrowed down to the problem happening when the program switched from HD to SD. The FIOS Motorola STB has positions Off, 480i, 480p, Stretch. Using the recommended Off or Stretch has been problem free for me, using 480i or 480p causes the video to go blank suddenly.
