I have a Samsung LE40A557 TV connected to a HT-C6500 Blu-Ray Home Cinema system via. HDMI cable. Set-up has been working successfully since June 2011. I disconnected the set-up to move the TV elsewhere in the room and reconnected then got no picture on TV with message on TV stating "Mode Not supported". I turned off HDMI Deep Colour setting on Blu-Ray player earlier and now TV screen has flickering/flashing red and Blu-Ray menu can be seen occasionally in background.

How do I resolve my problem?

I have uploaded a video to show what is being displayed on screen

My TV works ok with another Blu-Ray player (Panasonic) down the same HDMI lead.
My Blu-Ray player also works ok with another TV (Samsung)
