Troubleshooting
Initializing the internal memory
You can initialize the amp’s internal memory. As desired, you can initialize the following two types of data.
•
User Data
: Initialize all user data except for the event log and speaker processor library.
•
Library
: Initialize only the speaker processor library.
• When you initialize the internal memory, the settings that had been stored will be lost. Use the following procedure with
caution.
1.
Power-off the TXn.
2.
While holding down the [HOME] key, turn on the power; the Initialize screen will appear.
3.
Use encoder A to select the data that you want to initialize, and press the [ENTER] button to execute initial-
ization.
When initialization is completed, the amp will automatically restart.
• During initialization, the display will show the message “Do not turn off!” Never turn off the amp while this message is
displayed.
Symptom
Possible causes
Response
No sound from the
speaker
The cable is not connected properly.
Make the correct connections to the audio input jack and the
speaker output jack.
The gain or attenuator setting has low-
ered the level.
Gain is adjusted by the MENU screen

Sensitiv-
ity/Amp Gain. Attenuator is adjusted by turning the encoder in
the HOME screen.
The [MUTE] button is on.
If the front panel [MUTE] indicator is on, hold down the
[MUTE] button for one second or longer to cancel muting.
The protection circuit has operated, mut-
ing the output.
If the amplifier has overheated, clean the filter elements and
improve the ventilation around the amplifier. If the power sup-
ply has malfunctioned, contact your Yamaha dealer.
Noise from the speaker
The word clock from the slot input is not
synchronized with the master clock.
Select the word clock from the slot as the master clock, or
turn Auto Scan Mode on.
Analog input level is exceeding the input
sensitivity setting.
Adjust MENU screen

→
Sensitivity/Amp Gain set-
ting according to the input level.
An alert message is dis-
played
An amplifier malfunction or other alert event
related to the amplifier audio has occurred.
For details on the meaning of each alert message and the appro-
priate measures to take, refer to the Amp Editor Owner’s Manual.
Panel operations are not
accepted
The unit is locked.
Refer to “Front Panel Operation” in the TX6n/5n/4n Reference
Manual.
A scene can be saved

Enable setting ON.
Library can be recalled,
but not saved
You cannot save library data from the
TXn front panel.
Save the library data from Amp Editor.
All scene data saved in
the TXn has disappeared
The power was turned off while the TXn’s
data was being saved.
If you saved the project in Amp Editor, synchronize from Amp
Editor to the TXn.
To return to the default
parameter values
–
Recalling a scene 00 (default setting scene) will return all the
parameters other than those in the UTILITY settings to their
default values. The TXn allows you to edit a wide variety of
parameters, but can also be used as an analog amplifier by
returning to the default parameter values. Default values of
the main parameters are STEREO for amplifier mode, 26dB
for gain, and -
∞
dB for attenuation.
Refer to the TX6n/5n/4n Reference Manual for detailed infor-
mation on scenes.
