Replacing the Headphone Jack on a
Standalone Receiver
When someone using a receiver experiences no sound or poor
sound quality (such as intermittent sound or crackling), you should
check the headphone jack. Try moving the headphone plug in the
headphone jack. If the problem continues, the jack should be
replaced.
Installation and Maintenance Guide: Maintenance and Troubleshooting
What to Do
Make sure the display is on; the power
cable may be disconnected. Try
unmuting the receiver. Try turning up
the volume. Replace headphone jack.
Replace receiver.
Sound on TV or audio component may
be off or muted. Check the volume on
the equipment and increase the volume
or unmute as needed.
May be a problem with transmitter; see
Maintenance and Troubleshooting in
transmitter guide.
Transmitters were not installed in
channel order. Receivers automatically
assign transmitter channels to receiver
channels, from lowest to highest (see
Table 2). Move or reprogram transmitters
so channel numbers are in a logical
sequence. You will need to reprogram
receivers as well.
Moisture may have corroded the
electronics inside; replace the receiver.
The standalone receiver is designed to make changing the
headphone jack a quick and easy job, one easily done at the facility.
You will need a crosshead screwdriver to replace the headphone
jack. If you need to remove the receiver from its location to access
the screws, you will also need two new wire ties to reattach the
receiver, pliers, and a tool to cut the old wire ties.
You do not need to disconnect the power cable from the receiver to
perform this procedure.
1. Determine whether or not you need to remove the receiver from
its location to access the two screws on the back that hold the
headphone jack.
2. If needed, cut the two wire ties holding the receiver to the
equipment. Remove the wire ties from the receiver and toss.
3. Remove the two screws at the bottom of the receiver with a
crosshead screwdriver. See Figure 20.
