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 contr
oller
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).
You’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).
You’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.
Try 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.
You’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)
You’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).
