2 Batteries may be weak. Replace with new ones.
3 Operate the remote control no more than 20 feet from the device to be controlled.
4 Remove any obstacles between the remote and the DVD player or other components. If your DVD player is in an entertainment cabinet, and it has glass doors, they may be keeping the LED from the remote reaching the TV set or DVD. Open the doors.
5 The remote control may need to be reset. To do this, remove the batteries, and hold down one or more buttons for about 1 minute to drain voltage from the microprocessor inside the remote unit to reset it. Re install the batteries and try the remote operation again.

A screen saver icon appears on the TV screen Most DVD players are equipped with a screen saver that appears on the TV screen after your player has been idle for several minutes. There are a few ways to make the screen saver disappear from the screen and return to the player’s main menu. For example, press stop or go back buttons on the remote unit.

Subtitle and/or audio language selection The subtitle or audio language is not the one selected from the initial setting. If the subtitle and/or audio language does not exist on the disc, the initial settings will not be seen or heard. The disc’s priority language is selected instead. Set the subtitle and/or audio language manually through the info display on the DVD player menu.
