I have a Bravia KDL-40LX900 tv set and a BDV-F700 BlueRay/DVD/CD player. They were bought together about two months ago. They are connected using a HDMI cable. HDMI.based remote control integration for tv set and disc system is not enabled.

"Everything" works in the sense that I can play back a DVD or a BlueRay disc, and I can watch tv when the disc system is powered off.

Only one thing does not work: If I turn on the disc system, the TV set immediately loses its signal, and the screen becomes black, displaying a note saying something like "Bad tv signal".

If I power off the disc player, the tv image returns.

Only the image is gone - all the information about what is on etc. is still present.
