GOODMANS 1420R PORTABLE TV?

Try this which I found on the web:
Goodmans TVs often require you to press and hold the MENU key down to access the TV Tuning menu. Once activated, the VOLUME +/-, PROGRAM +/- and STANDBY buttons are used.
Alternatively, a key marked with three dots inside a rectangle (sometimes located near the mute key) needs to be pressed to enter the "MAIN" menu and then pressed again to enter the "ADMIN" menu. Once activated, the VOLUME +/- are used to store and the PROGRAM +/ to toggle the option. The TV button is used to exit the menu.
