Troubleshooting—Continued
Symptom Possible cause Remedy
Amp
A low-frequency noise or
hum can be heard?
The audio connecting cables at the rear of the
HT-R510 are too close to the power cord.
Untangle the audio cables and position them as far
away as possible from the power cord.
The sound is too bright or
harsh and the high range is
not clear.
The Treble function is set too high. Adjust the Treble function (pages 29, 37).
The subwoofer is not work-
ing or is very quiet?
The subwoofer mode is set to OFF or is set
incorrectly.
Check the subwoofer mode (page 25).
The volume of the subwoofer is set at mini-
mum.
Check the volume of the subwoofer (page 27).
Subwoofer output depends on the source mate-
rial. Some material may not use the subwoofer
much.
There’s no picture on the
TV or monitor?
The TV’s input selector is set incorrectly.
Select the correct input on the TV (i.e., the input to
which the HT-R510 is connected).
The video cable is not connected properly.
Check your video cables and connections
(pages 10–19).
The video input and output are different for-
mats.
The HT-R510 doesn’t convert between video formats.
It works as a video signal switcher. Composite video
input signals are output only by composite video out-
puts. S-Video input signals are output only by
S-Video outputs. And component video input signals
are output only by component video outputs.
Can’t hear an AV compo-
nent?
The wrong input source is selected. Select the correct input source (page 28).
Remote controller
The buttons on the
HT-R510 work OK but
those on the remote con-
troller don’t?
The wrong remote controller mode is selected. Select the correct mode (page 9).
There are no batteries in the remote controller. Install new batteries (page 5).
The batteries are flat. Replace with new batteries (page 5).
The batteries are installed incorrectly. Check the batteries and correct as necessary (page 5).
Yo u’re not pointing the remote controller at the
HT-R510’s remote sensor.
Point the remote controller at the HT-R510’s remote
sensor (page 5).
Yo u’re too far away from the HT-R510.
Use the remote controller closer to the HT-R510
(page 5). The remote controller has a range of
approximately 16 ft. (5 meters).
A strong light source is interfering with the
HT-R510’s remote sensor.
Make sure that the HT-R510 is not subjected to direct
sunshine or inverter-type fluorescent lights. Relocate
if necessary.
If the HT-R510 is installed in a cabinet with col-
ored glass doors, the remote controller may not
work reliably when the doors are closed.
Open the doors, or use a cabinet without colored
glass.
Can’t use the remote con-
troller with other AV com-
ponents?
The wrong manufacturer’s code has been
entered.
Tr y entering the code again (page 40).
If more than one code is provided, try them all
(page 40).
With some manufacturer’s AV components, certain
buttons will not work as expected.
Yo u’re pointing the remote controller at the
wrong AV component.
To control an AV component connected via ,
point the remote controller at the HT-R510. To con-
trol an AV component that’s not connected via ,
point the remote controller at that AV component
(page 41)
Yo u’ve made an connection but not an ana-
log RCA/phono connection.
To use , you must make an connection and an
analog RCA/phono connection between the AV com-
ponent and HT-R510, even if they are connected dig-
itally (page 19).
