I have connected my Sony BDPS370 bluray player with my Sony KDL46EX503 TV using a HDMI cable. The player appears to work fine, but on the Bravia Sync menu on the list of connected devices the description is "no device detected". The HDMI control device is switched to "on" for both the player and the TV.

Does anyone have a solution, please, as one of the reasons that I purchased the Sony BD player was so that it would sync up with the TV?

All any help will be gratefully received.
