the Ac outlet is not controlled by a switch.

 

• Make sure that the Master Power switch (on the player’s rear panel) is in the “On” 

position.

dvd-video, dvd+R/+RW, dvd-R/-RW, cddA (cd digital audio), cd-R/RW. Other 

disc types will not play.

not hdcP-compliant.

No sound:

 

• check that the hdMI and/or coaxial digital connections are properly made.

the connected device have been properly set.

 

• If you’re using only the hdMI connection, check that the hdMI audio settings on the 

connected device have been properly set.

The player does not respond to remote-control commands:

 

• Replace both remote-control batteries with fresh ones, and make sure that they are 

installed correctly.

 

• hold the remote control closer to the player.

 

• check that the player’s remote sensor is in the remote control’s line of sight.

back in.
