HD Cable Box produces blank screen. help!

I recently added another HDTV to my house so I got another cable box. The Motorola DCH3200 from Cox Cable. I have it hooked up with component cables running to the TV and then I have an optical audio cable running from the TV to my surround sound receiver. Well everything worked fine for a while then I switched to another input on my TV to play a videogame. When I come back after an hour or two to the cable, it gives no picture. I tried to reset it by unplugging it and plugging it in but nothing happens. It doesn't even update the time.

I tried replacing the box and the same thing happened after a few hours. The box still worked when I hooked it up to an SDTV in another room through the RF out but it didn't work with my other HDTV through HDMI. Is there some setting I'm missing where the output gets moved from component or HDMI over to RF or composite? I've read through the manual about 6 times and talked to a tech at Cox. I'm absolutely certain it's not a problem with my cable lines in my house as it was working earlier, and it won't work on the brand new line that is running to my other HDTV. Please help, I'm clueless! Thanks.
