I have seen this on some 720p HDTVs but the fix is to reset the Sony and then go through the setup. Can upset those that want to move such around the sets but if the Samsung is not 1080p you may have to do this.
I have a 2 year old Samsung TV and just bought a Sony S390 blu ray player. When I turn on the Blu ray player, it displays the welcome screen on my TV, then attempts to go to the menu and signal is lost. I hooked it up to my Vizio TV using the same HDMI cable and works fine. I'm not sure if this is an issue with the player or the TV. The player seems to still be on and TV not registering signal.
