• Lightning storms.

• High static electricity environment.

• Poor voltage regulation in the power source.

If the Rear Projection TV does not operate properly, reset it as follows:

1. Unplug the AC cord.

2. After approximately 1 minute, turn on the power with switch and 4 POWER button.

If the normal operation cannot be restored after the above treatment, immediately unplug the power cord and call your nearest SHARP-authorized service center.

On rare occasions, an electrical discharge may occur inside the CRT. It makes a short, sharp pop and either no sound is produced or the volume level changes by itself. The TWIN PICTURE and SEARCH SCREEN function will be cancelled automatically if an electrical discharge occurs when this function is engaged.
