Troubleshooting the Jensen JHT525 Surround System

Troubleshooting the Jensen JHT525 Surround System
Problem:	Solution:
SUBWOOFER POWER INDICATOR LED DOES NOT LIGHT:	Check that the Subwoofer’s POWER switch is in the ON position. If the POWER Switch is in the ON position, check the AC outlet the Subwoofer is plugged into to be sure that it is live. You can use a tester or plug in a lamp to check it. If the AC outlet is live, either the power cord or Subwoofer has a problem. Unplug the power cord from the AC outlet and check the fuse by unscrewing the center piece from the holder. If it is blown, replace the fuse only with a fuse of the same type and rating. If this doesn't help, take the Subwoofer to your dealer for service — THERE ARE NO USER-SERVICEABLE PARTS INSIDE.
NO SOUND FROM THE FRONT SPEAKERS:	Be sure the Receiver and Subwoofer POWER switches are in the ON positions. Check the Receiver’s Volume Control setting — if it is all the way down, there won't be any sound. Check that the Receiver’s Input Selector is set to an active source of audio signals and that a Tape Monitor Loop is not engaged. Be sure that the Receiver’s Speaker Selector switch is turned on to the terminals [A or B, 1 or 2] that you have your Front speakers connected to. If the Receiver has a headphone jack, you can use headphones to check the Receiver for output. Check the wires and connections from the Receiver’s Front Speaker Output terminals to the Subwoofer’s SPEAKER-IN terminals. Try removing the Subwoofer from the system, leaving your Front speakers connected to the Receiver. If there still is no sound, take the Receiver to your dealer for service.
NO SOUND FROM THE SUBWOOFER:	First, be sure there is sound from the Front speakers and that the Receiver is working correctly as outlined above. Check the Subwoofer’s LEVEL control. If it is all the way counterclockwise, there may be no sound. The Subwoofer only reproduces deep bass sound. If the program has no deep bass, the Subwoofer will not make any sound. Play a program with plenty of bass, such as jazz or rock music, or an action movie. If everything else checks OK, take the Subwoofer to your dealer for service - THERE ARE NO USER-SERVICEABLE PARTS INSIDE.
