If your JBL CINEMA BASE system does not perform the way you think it should, check whether the problem is covered in this section before contacting your 
dealer or a JBL representative.

If the soundbase does not turn ON

•  Check if the soundbase power supply’s AC cord is plugged into a working AC

outlet and that the power supply is plugged into the soundbase. 

If there is no sound coming from the soundbase

•  Check if soundbase is ON (the power indicator should be white).

•  Check if the cable connecting the TV to soundbase is properly connected at

both ends. 

•  Check if the soundbase’s Source Selector is set to the correct source and that

source is playing an audio signal. 

•  Check if the system is not muted. If the system is muted, press the volume

buttons to un-mute the system. 

•  Check if the soundbase’s volume is not turned all the way down (the lowest

setting of the Volume Down button will mute the system).

If the soundbase’s sound is distorted

•  Check the source component to see if the distortion is coming from it, and not

from soundbase. 

If there is NO sound from the system, even when the soundbase’s volume is

turned all the way up 

•  If the TV or source component is connected via a variable output, check its

instructions if the output is not turned down too low. 

If the bass output is not loud enough

•  Turn up the soundbase’s bass volume using the remote control.

The volume is reset when I turn on the soundbase

playing at more than 50 percent of maximum volume and the power is turned

off, the volume of the soundbase is automaticalluy reset to 50 percent of the

maximum volume when the system is turned back ON.

My TV is ON and my JBL CINEMA BASE is in Standby. When I switch off my

television, it turns my JBL CINEMA BASE ON

Plug Detection (HPD) protocol. You can activate/deactivate HPD protocol by

pressing the Surround and Volume buttons simultaneously.
