HT-SL72 / HT-SL77 ZB271
Many potential problems can be resolved by the owner
without calling a service technician.
If something is wrong with this product, check the following
before calling your authorized SHARP dealer or service
center.
* For HT-SL77
Sudden temperature changes, storage or operation in an
extremely humid environment may cause condensation
inside the cabinet. Condensation can cause the unit to
malfunction. If this happens, leave the power on until
normal playback is possible (about 1 hour).
When this product is subject to strong external interference
(mechanical shock, excessive static electricity, abnormal
supply voltage due to lightning, etc.) or if it is operated
incorrectly, it may malfunction.
If the unit is not restored in the previous operation,
unplug and plug in the unit again
or
unplug all component connected and plug in again.
During the Amplifier power on position (BLUE indicator
light up), press the PAIRING button for more than 10
seconds.
Note:
This operation will restore the DIGITAL (HDMI) function
volume to the default setting.
Periodically wipe the cabinet with a soft cloth.
Caution:
● Do not use chemicals for cleaning (gasoline, paint
thinner, etc.). It may damage the cabinet finish.
● Do not apply oil to the inside of each component. It may
cause malfunctions.
Symptom Possible cause
● No sound is heard
from Sound Bar/
Subwoofer.
● Is the TV input signal
(selection) set properly?
● Is HDMI compliant
equipment being used?*
● Is the HDMI cable
connected correctly?*
● Is the HDMI cable of the
correct type being used?
(with ARC)*
● Does the sound input
support PCM signal?*
● Do not connect or
disconnect an HDMI cable
while power is on. This
may lead to operation
problems.*
● Check if the Subwoofer
already turn on.
● Manually re-link the
Amplifier and Subwoofer

not the Sound Bar
problem.
Symptom Possible cause
