HDMI no signal amnesia!

At my wits end...
Recently purchased Samsung home theatre (HT) system (HT-C7200XEE) and linked it to Samsung TV (LE32B455C4W) via HDMI cable. The link worked perfectly for a while until i fiddled around (as one does!). Since then the 'no signal' torture. I've tried...
-Various combinations of on-off switching of the systems and cable disconnect-connect
-New HDMI cable
-Changing HDMI ports on the TV and HDMI cable ends between systems
-Fiddling around with screen resolution
-Upgraded TV software but not HT (since I can't get the HDMI link to work so can't see and select upgrade!)
The link to my PC is lost to which leads me belive the TV is the problem and not the HT system.
The TV picks up the HDMI cable (HDMI 2, 3 connections are shown when changed) but the handshake does not happen. How can the HDMI link perfectly and then suddenly fail?
Totally out of ideas here. Must be some kind of setting. HT just gathering dust.
Any suggestions techno folks!
