I've had something strange happen with my 722 recently. When turning it on, I get no picture or sound. All of the menus, info, etc. work fine. I have to reset the unit, then everything is back to normal. What's really weird is that it's only happened twice, both times in the last week, and both times early Thursday evening. Each time it happened, a recording was taking place and the recordings were perfect (I waited to reset until after the recordings were done). I have OTA hooked up to the unit and there was no picture or sound on any of those channels either.
Obviously there's a glitch in the software, but wondering if anyone else has had this happen and if it may be a precursor of unit failure.
