This is where the sammy instructions leave me baffled. It says in "Stop Mode" push and hold sd/hd button. Well it does not tell you what function to be on to get to stop mode and what you will see etc. The only way we can seem to get into the sony logo or menu screen is to select "USB" function, which makes no sense. Then once I get there, sometimes I can push the menu button and get the menu and sometimes I can't. Maybe this has to do with stop mode, i don't know... it doesn't do anything if I push "Stop" and the "Menu". The times I do manage to get the menu to come ip and push and hold sd/hd it does the same thing as trying it at the sony log o scren...which is this: push and hold the sd/hd button and on the theater screen (not the TV screen) it will flash 720p and if you continue doing this you can cycle through 1080i and 480p too. I have tried setting it to each of these then pressing the Aux button on the remote until I am back to HDMI In. I get the same error on the TV whether I have 720, 1080 or 480 selected..."Unsupported signal. Check your device output". So I really do not understand this sammy at all.
