TROUBLESHOOTING

f there is no sound from

any of the speakers:

• Check that receiver/ampli-

fier is on and that a source is

playing.

• Review proper operation of

your receiver/amplifier.

If there is no sound

coming from one

peaker:

• Check the “Balance”

control on your receiver/

amplifier.

• Check all wires and con-

nections between receiver/

amplifier and speakers.

• Make sure no wires are

touching other wires or

terminals and creating a

short circuit.

• Make sure all wires are

connected. Make sure none

of the speaker wires are

frayed, cut or punctured.

• In Dolby

Digital or DTS

modes, make sure that the

receiver/processor is config-

ured so that the speaker in

question is enabled.

• Turn off all electronics and

switch the speaker in ques-

tion with one of the other

speakers that is working cor-

rectly. Turn everything back

on, and determine whether

the problem has followed the

speakers, or has remained

in the same channel. If the

problem is in the same chan-

nel, the source of the prob-

lem is most likely with your

receiver or amplifier, and

you

should consult the owner’s

manual for that product for

further information.

If the

problem has followed the

speaker, consult your dealer

for further assistance or, if

that is not possible, visit

www.jbl.com for further

information.

If the system plays at

low volumes but shuts

off as volume is

increased:

• Check all wires and con-

nections between receiver/

amplifier and speakers.

• Make sure all wires are

connected. Make sure none

of the speaker wires are

frayed, cut or punctured.

• If more than one pair of

main speakers is being used,

check the minimum imped-

ance requirements of your

receiver/amplifier.

If there is no (or low)

bass output:

• Make sure the polarities

(+ and –) of the left and right

“Speaker Inputs” are

connected properly.

• Consider adding a powered

subwoofer to your system for

use with digital “.1” surround

formats.

f there is no sound from

the surround speakers:

• Check all wires and con-

nections between receiver/

amplifier and speakers.

Make sure all wires are con-

nected. Make sure none of

the speaker wires are frayed,

cut, punctured or touching

each other.

• Review proper operation of

your receiver/amplifier and

its surround sound features.

• Make sure the movie or TV

show you are watching is

recorded in a surround

sound mode. If it is not,

check to see whether your

receiver/amplifier has other

surround modes you may

use.

• In Dolby Digital or DTS

modes, make sure your

receiver/processor is config-

ured so that the surround

speakers are enabled.

• Review the operation of your

DVD player and the jacket of

your DVD to make sure that

the DVD features the desired

Dolby Digital or DTS mode,

and that you have properly

selected that mode using both

the DVD player’s menu and the

DVD’s menu.
