Windows Media Center - no channels found

This was working a couple of days ago.
But I noticed the Exclamation icon yesterday - 'no tv signal'.

So, I've tried reseating the coax (external antenna), and even using a small desktop antenna, but the result is the same - no channels...

Running the wizard, it finds the tuners, but no channels.  
Just want to make sure I've done my due diligence here.  Any ideas on how to get this working again?

It's possible that a software glitch has happened(virus/conflicting windows update/bad shutdown etc.) A solution may be to perform a system restore to a point when you know it was working.

Hmm - I doubt that's the problem.  The last restore point was 11/30 - that was the last windows update/change to the system, and that's about 3 days prior to the issues that began yesterday...

It doesn't hurt to try.  You can always revert your restore back to where you are now..

No good - went back to the oldest, aside from the very first one, and it still doesn't see a signal...

Weirdest thing - I ended up checking out the wiring downstairs...it's been working all of this time without any antenna hooked up to it. :S
I had to do a bit of re-wiring, but now it's working.  Very bizarre, but points are yours for helping.  :^)

Hmm I'm glad you figured it out. I know with computers they will see wireless networks without the antenna connected just using the copper in the wires themselves to detect the signal and if you connect the antenna it's 10 times better but it will work that way.  Thanks for the response.

Eh, turns out that wasn't the problem.  I just happened to get one channel working, but only briefly.
I think the card must be going bad. :(
I've emailed support - hoping to hear from them.
