1. Make sure the full mute setting is not activated. The message �FULL MUTE ON� will appear in the top-left corner of the on-screen and front panel displays when the full mute setting is activated. Press the Mute button or adjust the volume level to deactivate the full mute setting. 2. Increase the volume level to make sure it is set to an audible level. 3. Check the STATUS menu to ensure a signal is coming into the unit. (Press SHIFT, then STAT on the remote control to access the STATUS menu.) 4. Make sure the associated power amplifier(s) are powered on. THE UNIT IS ON, BUT THERE IS NO VIDEO. 1. Check the video cables, particularly the S-video cables, to ensure good connections. 2. Check the VIDEO IN and COMPONENT IN parameters on the INPUT SETUP menu (see pages 3-8 and 3-9). Make sure the appropriate connector is assigned to the selected input. DIALOG SOUNDS MUFFLED. 1. If the system does not include a center channel, make sure the CENTER parameter on the CUSTOM SETUP menu is set to NONE (see page 3-20).

THE UNIT DOES NOT POWER ON. 1. Attempt to power the unit on with both (standby) buttons, the one on the front panel, and the one on the remote control. 2. Check the line cord to ensure a good connection between the electrical outlet and the AC input connector. Make sure the rear panel power switch is set to on. (See pages 2-4 and 2-7 for rear panel illustrations.) THE REMOTE CONTROL DOESN�T WORK. 1. Make sure the front panel IR Receiver window is not obstructed (see pages 2-2 and 2-6 for illustrations). The remote control must be in line-of-sight with this receiver for proper operation. If the unit is placed inside a glass cabinet, smoked glass will reduce the range of the remote control. 2. Make certain the batteries are inserted correctly with the proper polarity. Are the batteries low on power? When the they are, the remote control will enter a low-voltage condition that prevents it from operating the unit. Operation will be restored when new batteries are installed.
