Baffling and infuriating: Ability to use TV as external monitor for Macbook Pro has disappeared overnight!

* Latest-issue Macbook Pro (13-inch)
* 2009 (I think) Panasonic Plasma TV (TC-P50G10).
* Connection is from Mac's mini-displayport, to a MDP/HDMI adapter from monoprice.com; to an HDMI cable; to the TV.
This worked fine last night, and previously. I would connect the cable, the Mac's screen would go to blue, then the TV's would follow suit, and then both would come up with the computer's display.
Now, when I connect the cable, the Mac's screen still goes blue -- i.e., on some level, it detects the connection. But the TV's screen does nothing.
(The only change I can remember making: When I had this connection running last night, I changed the Mac's setting from "Mirror display" to "Extend desktop," and I don't think I changed it back before unplugging the TV from the Mac. But surely that doesn't explain why the TV is not responding at all right now!?)
Guidance/ suggestions gratefully appreciated!
