Windows 7: HDMI Headscratcher

There have been several firmware updates since I go the TV about a year ago. It is a Samsung PV64F8500 (plasma) "Smart TV" that is always "on/on-standby" and connected to my network (for Netflix, Hulu, and similar apps). When an update is available, a message scrolls across the top of the screen. You can do the update now or it will automatically update itself later. At least it tells you its updating (but I have no idea why it needs to update).

My issue is a little different from the OP's. But the solution may be the same if the problem is related to HDCP or "handshaking" (EDID). I'm going to borrow a "HDCP striper" and see if that does anything.

BTW - I did not unplug the TV and let it sit, and then retest. I forgot about this advice - and its "free and easy", so I'll do that tonight.

I did restart the computer while the TV is on (several times). When I do this I can see the PC boot up (read the BIOS screen). It goes all the way to the Windows Starting screen then I lose the signal (TV says " no source detected" at that point.

CB, if the pc boots all the way to the opening screen isn't that an indication of the drivers of the pc kicking in? If you've already thought of that, sorry
