I have just purchased a Panasonic SC-BT222 and have it connected to my Sony Bravia KDL-37EX503. I have 3 questions. Firstly, I have noticed on a couple of occasions that the picture has dropped out and the sound continues. Any thoughts on why this may have happened ? Secondly, when the BluRay player is turned on, the TV speakers are disabled. Is there a setting on the BR that will allow the TV speakers to work when it is connected switched on ? Finally, a message appeared about checking for firmware upgrades. How do I go about this ?
