My friend bought a SV2000 DVD recorder to use on her Magnavox TV (model # 25f800 7583) but the tv is mono. She connected the coaxial correctly, but the tv itself does not let her turn to AUX, INPUT, etc. through the remote nor on the tv itself. It only has a MENU button, but it does not work. She's tried channels, 2,3,4 and went below 2 to see if the AUX/ INPUT would be accessed that way, but no luck. Any suggestions?
