No HDMI Support
I just had my cable updated to HD, which uses an HDMI cable. The guy came in, got it hooked up, and all was fine. But, recently, I've been getting a black screen with a "Not Supported" message (on my TV), after switching to the proper HDMI port. I've switched HDMI cables, tried rebooting the Explorer 8300HD cable box, and tested the two HDMI ports on my TV with other systems (which works for them). Nothing helped. The box only has one HDMI port, so I can't test that.

Try using the component outputs. The S/A (and Cisco) DVRs have suspect HDMI circuitry. That 8300HD DVR is an antique. Its EOL (end-of-life) was in 2009. I recommend the 8642HDC, or the 8742HDC. If you need digital and analog tuners in your DVR (not many Cox systems require this), get an 8752HDC.
What model is your TV?

That sounds like all of the standard troubleshooting we suggest to try for situations such as yours. At this point I suspect the HDMI on the box has possibly failed. Feel free to exchange the box at one of our solutions stores and see if that helps resolve the problem.

You were charged $60 for a HDMI cable install? The HDMI signal may well work on a different TV. Cisco DVR HDMI circuits don't play as well with some TVs as with others. That's why I asked you what model TV you have. The EOL chart from Cisco for the 8300HD:
