Uh...that was weird. I guess I hit a button. Anyway...

The PC is now connected to the 990 via DVI<->DVI cable. The 990 is connected to the TV via the DVI<->HDMI cable.

The PC is on all the time, but the TV and 990 of course are switched off between uses.

The problem: occasionally when I turn on the TV and the 990, setting the TV to the HDMI input and the 990 to the proper input, I get no video. There is audio, and I know the PC is still working because I can use the keyboard to reboot.

Any troubleshooting questions and suggestions are welcome. I had a similar issue with my Xbox a while back and I ended up having it repaired under warranty and the problem went away.
