Sony str-dg510 User Manual

If you experience any of the following 
difficulties while using the receiver, use this 
troubleshooting guide to help you remedy the 
problem.

• Check that the speakers and components 

are connected securely.

• Check that both the receiver and all 

components are turned on.

• Check that MASTER VOLUME is not set 

to “VOL MIN”.

• Check that the SPEAKERS (OFF/A/B) is 

not set to “OFF”.

• Check that headphones are not connected.
• Press MUTING to cancel the muting 

function.

• Check that you have selected the correct 

component with the input buttons.

• The protective device on the receiver has 

been activated. Turn off the receiver, 
eliminate the short-circuit problem, and 
turn on the power again.

• Check that the component is connected 

correctly to the audio input jacks for that 
component.

• Check that the cord(s) used for the 

connection is (are) fully inserted into the 
jacks on both the receiver and the 
component.

• Connect a pair of headphones to the 

PHONES jack to verify that sound is 
output from the headphones. If only one 
channel is output from the headphones, the 
component may not be connected to the 
receiver correctly. Check that all the cords 
are fully inserted into the jacks on both the 
receiver and the component. If both 
channels are output from the headphones, 
the front speaker may not be connected to 
the receiver correctly. Check the 
connection of the front speaker which is 
not outputting any sound.

• Make sure you have connected to both the 

L and R jacks of an analog component, and 
not only to either the L or R jack. Use an 
audio cord (not supplied).

• Check that the INPUT MODE is not set to 

“OPT IN” (page 58).

• Check that the INPUT MODE is not set to 

“ANALOG” (page 58).

• Check that ANALOG DIRECT is not set 

to on.

• Check that the speakers and components 

are connected correctly and securely.

• Adjust the balance parameters using the 

LEVEL menu.
