Why will my receiver not turn on - Sony STR-DE405

To link the Futaba FF6 T6X with the GWR-8M receiver, you need to follow these steps:

1. Turn off the transmitter and the receiver.
2. Connect the GWR-8M receiver to the servos and the battery.
3. Turn on the transmitter and set it to PPM mode.
4. Press and hold the Link button on the GWR-8M receiver.
5. Turn on the receiver while still holding the Link button.
6. Wait for the LED on the GWR-8M receiver to turn solid, indicating that the binding process is complete.
7. Release the Link button and turn off the receiver and transmitter.
8. Turn on the transmitter and then turn on the receiver to confirm the link has been established.

Once the link is established, you should be able to control the servos using the Futaba FF6 T6X transmitter. If you encounter any issues, refer to the user manual for both the transmitter and receiver for troubleshooting tips.

Disconnect the speakers on Zone 2 and try to turn on the receiver again. If the receiver works, there is a shorted speaker wire, pinched wire, or a blown speaker on zone 2. Good Luck

What is the source of your music? And how it is connected to the receiver? If via HDMI, then it is not possible. Source HDMI device will not put any audio into the HDMI when the display device is not turned on (it must authentificate with the TV to be sure you are not doing any unauthorized copying).

If your only issue is that when you turn off TV it turns off the receiver, then turn on the receiver only after you have turned off the TV. If this causes the TV to turn on also, you have HDMI CEC enabled. HDMI CEC enabled devices to communicate with each other via HDMI - receiver can tell TV to turn on/off. You can disable the HDMI CEC support in receiver menu if you want. After that, your TV and receiver will turn on/off independently of each other.

With the unit on, try a reset. If there is a small hole in the back somewhere, gently poke a toothpick in about 1/4". You should feel a soft click. If there is no reset hole, disconnect the power cord for a day or 2. If that doesn't help, you'll have to take it in for repair.

The regulator is bad.

Does it turn off with all the wires disconnected from the back of it?

Try checking your speaker cables as one of them may be touching the case of the amp,or touching another cable,this can cause a short and cause the error message.The amp is protecting itself .
hope this helps.

Suggest turning the volume down on the Receiver/Amp before changing modes. Changing modes can produce signals that can hurt speakers if driving at mid-high levels.

Regarding the sub, turn off the receiver first, then turn off the sub. When turning everything on, turn on the sub first, then the receiver. If you still hear the noice in the sub, turn down the volume in the sub before turning it off (making note of what volume level you prefer for it when it is on).
