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
TX-SR501/TX-SR501E 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 TX-SR501/TX-SR501E 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 TX-SR501/TX-SR501E doesn’t convert between
video formats. It works as a video signal switcher.
Composite video input signals are output only by
composite video outputs. 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
TX-SR501/TX-SR501E
work OK but those on the
remote controller 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
TX-SR501/TX-SR501E’s remote sensor. Point the remote controller at the TX-SR501/
TX-SR501E’s remote sensor (page 5).
You’re too far away from the TX-SR501/
TX-SR501E.
Use the remote controller closer to the TX-SR501/
TX-SR501E (page 5). The remote controller has a
range of approximately 16 ft. (5 meters).
A strong light source is interfering with the
TX-SR501/TX-SR501E’s remote sensor.
Make sure that the TX-SR501/TX-SR501E is not sub-
jected to direct sunshine or inverter-type fluorescent
lights. Relocate if necessary.
If the TX-SR501/TX-SR501E is installed in a
cabinet with colored 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 41).
If more than one code is provided, try them all
(page 41).
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 TX-SR501/
TX-SR501E. To control an AV component that’s not
connected via
, point the remote controller at that
AV component (pages 40, 42)
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 TX-SR501/TX-SR501E, even if they are
connected digitally (page 19).
