SA-PT760 Wireless Troubleshooting Plan
Wireless rear does not work – W1 or W2 display icons do blink at power on.
1.RF connection has not been made. Go to slide 6 to pair the transmitter and receiver. Steps 1-6.
2.Go to slide 8 to troubleshoot the receiver. Make sure there is standby voltage input the receiver and the pair button is working (pin 9 grounds when the button is pressed.
3.Go to slide 7 to check the transmitter card Sw +5V voltage at the main board (CN2003) or at the card socket itself CN6301).
Wireless rear does not work – W1 or W2 display icons do NOT blink at power on.
1.The RF connection is OK. No audio is the problem. Replace the transmitter card if hot (damaged when plugged in while the unit was powered on).
2.Go to slide 6 and follow steps 7 to turn on “S Music” mode (surround music). This makes the rear surround speaker sound the same as main L & R.
3.Input an audio source (play some music).
4.Disconnect the speakers and turn the volume control to max (level number 50 is displayed).
5.Go to slide 8. Check for audio at the receiver card CN1100/pins 2 & 4.
6.If there was no audio present at CN1100 (receiver), Go to slide 7. Check for audio at the transmitter socket CN6301/pins 10 & 12.
