Receiver to hear sound from the A/V receiver speakers.
• Perform a System Reset.
2. The sound does not match the screen
picture.

quality).
Upgrade a Category 1 (unmarked) HDMI cable to a Category 2
HDMI cable.

cause the edges of the image to be cut off. Press FORMAT on
the TV remote control to adjust the size.

ing red.
