I have an old home theater system from panasonic.It includes the 5 small speakers,a subwoofer and a DVD player.When I set the DVD player to TV (choosing between AUX TV DVD/CD AM FM)i cannot see anything.The system is connected to the tv only through a SCART cable in the AV1 port.I cant see anything when I switch to AV1 on TV.I am sure the system works because i can see an image when i set it to DVD/CD,but i can`t access the menu from there.Any help is appreciated!
