I have a sansui PDP42TD1 TV. The picture is rolling and the sound is poor. When I press the Input button on the remote, The screen displays "AV invalid". I have tried the menu picture settings and Tools "Scan Source", but the remote has no "enter Button" so I don't kmow how to initiate a scan of any kind!
