I'm facing this weird problem on my Videocon D2H standard box (around 10 - 11 months old) since the last two-three days. The volume automatically goes off while watching, across all channels. The only way to get it back it to completely switch off the box from the mains and turn it on again. This happens atleast three four times a day.What could be the problem. Is it the box that's the culprit?
