Remove all the cameras then reboot. If it boots up normally then shut down dvr and add a camera and repeat. If it doesn't solve the problem, the issue is probably a video card or motherboard issue and will need to be repaired or replaced.

SOURCE: Normal Picture Mode Not Available With Cox HD-DVR (Motorola DCH3416) and HDMI Cable

With an HDMI cable connected, the cable box determines the picture size. The settings on the cable box must be changed in order for you to get the correct picture size. I have some experience with Motorola cable boxes; usually to access the settings you turn the box OFF and then press the menu or settings button on the box to bring up the display menu. Hope this helps!

SOURCE: White/Grey screen with non-HD channels

I removed the HDMI cable and connected with component video and rca audio. No more white screen.

Picture quality looks good. I don't know if it's as good as HDMI, but then I don't need to reboot the TV three times to get to teh on-demand menu... Grrrrr....

I am trying to contact Toshiba on this as well. I have seen several reports of this problem on the web.

Inside, you'll find a small button cell. Remove it, and leave the machine switched off for a few hours. When you replace the battery and switch the machine back on, the password will be reset.
