My BD5200 player had been working perfectly with my Panasonic TH-42PZ700BA until I needed to replace the HDMI cable. The old cable had been yanked thus separating the cable from the plate which goes into the DVD player. I now have a new HDMI cable but I cannot get a picture.

I took the player to local electronic repair shop but the owner, and using his own HDMI cable, was also unable to get a picture. I took the player home and used the 'reset picture' code as suggested in the troubleshooting section of the player guide. I then got a 'HDCP Err' message. I understand that there is probably a problem with the 'handshake' between the player and the TV. I've no idea why as they had both worked perfectly well before.

Any ideas how I might rectify this problem?

Many thanks
