Pionerr 810 loses picture but not sound

[hddude55]

For about a year, every day or two the Pioneer 810's picture disappears, yet the sound is present and recordings are made. Unplugging the 810 brings back the picture, but of course, that entails an annoying wait for the 810 to reboot. Any idea what's going on?

What source input are you using (S-video, coax, composite)? Do you use your TiVo with a cable box? What happens to the video (All black or grey)?

Composite input with no cable box. If the picture is present it stays OK while watching, but a day or two later when I turn on the TV to watch something it's a crap shoot whether I will get picture/sound or just sound with a black screen. Pulling the plug always brings back the picture but only for a few days.
