TX-8270 - Troubleshooting: Audio
Problems may be solved by simply turning the power on/off or disconnecting/connecting the power cord, which is easier than working on the connection, setting and operating procedure. Try the simple measures on both the unit and the connected device. If the problem isn't fixed after referring to "Troubleshooting", resetting the unit to the status at the time of shipment may solve the problem. Note that your settings will also be initialized when you reset, so we recommend that you note down your settings before doing the following.
- This unit contains a microPC for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least 5 seconds, and then plug it back in.
- We are not responsible for reparations for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s malfunction. Before you record important data, make sure that the material will be recorded correctly.
Try restarting the unit
The issue may be fixed by restarting this unit. After switching this unit to standby, press and hold Í ON/ STANDBY on this unit for 5 or more seconds to restart the unit. (The settings in the unit are maintained.) If the issue is not fixed by restarting, try unplugging the power cords of the unit and connected devices, and then plugging them in again.
Resetting the unit (this resets the unit settings to the default)
If restarting the unit doesn't fix the problem, resetting the unit to the status at the time of shipment may solve the problem. Your settings will also be initialized when you reset, so note down your settings before doing the following.
- While holding down TUNING MODE on the main unit, press ON/STANDBY.
- 2. The unit switches to standby and the settings are reset.
Before you start...
- Confirm that the connection between the output jack on
the device and the input jack on this unit is correct. - Make sure that none of the connecting cables are bent,
twisted, or damaged. - If the MUTE indicator on the display flashes, press
MUTING on the remote controller to cancel muting. - While headphones are connected to the PHONES jack,
no sound is output from the speakers.
There is no sound from the TV
- Change the input selector on this unit to the position of
the terminal to which the TV is connected. - When connected to a TV that supports the ARC feature
with an HDMI cable, only PCM audio input is supported
from the TV to this unit. Make sure that your TV audio
output setting is set to PCM. - If the TV doesn't support the ARC function, along with
connection by HDMI, connect the TV and this unit using
a digital optical cable, digital coaxial cable, or analog
audio cable.
No sound from a connected external device
- Change the input selector on this unit to the position of
the terminal to which the external device is connected. - Check the digital audio output setting on the connected
component. On some game consoles, such as those that
support DVD, the default setting is off. - Only PCM audio is supported for input through the
DIGITAL IN OPTICAL/COAXIAL jacks. Set the audio
output on the external device to output PCM.
A speaker produces no sound
- Make sure that the polarity of the speaker cables (+/-) is
correct, and that no bare wires are in contact with the
metal part of speaker terminals. - Make sure that the speaker cables have not shorted.
- Make sure the speakers are connected correctly.
The subwoofer produces no sound
If the setting of the front speakers is "Full Band" and during
2ch input such as from the TV or music, the low range
elements will be output from the front speakers rather than
from the subwoofer. If you would rather output from the
subwoofer, make one of the following settings.
- Change the front speakers settings to a setting other
than "Full Band" for the crossover frequency value.
The range below the frequency you specify will be output
from the subwoofer rather than the front speakers. We
do not recommend changing this if your front speakers
have good low range reproduction capabilities. - Change "Double Bass" to "On".
The low range elements will be output from both the front
speakers and the subwoofer. This may mean that there
is too much bass. Do not change if this happens, or
choose option 1.
- Refer to "2. Speaker" - "Crossover" in the Setup
menu for details. - When you play source material that contains no
information in the LFE channel, the subwoofer produces
no sound.
Noise can be heard
- Using cable ties to bundle analog audio cables, power
cords, speaker cables, etc. may degrade the audio
performance, Do not bundle cords. - An audio cable may be picking up interference. Try
repositioning your cables.
The beginning of audio received by an HDMI IN cannot be heard
- Since it takes longer to identify the format of an HDMI
signal than it does for other digital audio signals, audio
output may not start immediately.
Sound suddenly reduces
- When the temperature inside the unit exceeds a certain
temperature for extended periods, the volume may be
reduced automatically to protect the circuits.
There is no linked operation with CEC compliant devices, such as a TV.
- The "5. Hardware" - "HDMI" - "HDMI CEC" setting in the
Setup menu needs to be set to "On". - It is also necessary to set HDMI linking on the CEC
compliant device. Check the instruction manual.
