TX-NR747 Error Code

Unboxed and set up the above today- it's been in storage since I bought it last year as the building work has taken far too long for the home cinema it was for.

Put it into set up mode, all going well then it just shut down.

Repeated steps to turn it on result in the following on the display panel: NG:LCRSLSRBLBR

I've tried to reset it, but nothing.

Before I return it to Richer Sounds, any suggestions?

Hi Jasons,

this error code means, that there was something wrong with the installation from the speakers.
Please disconnect the speakers from the AV-Receiver and make the following steps to close the Diag Mode:

1. Disconnect all Speaker wires from the unit

2. Turn on the receiver.
Press and hold "Enter" and then press "Standby" (in order to reset ‘’Diag mode’’). Usually the receiver turns off automatically then go to -4-. If not then proceed to -3-.

3. After that press standby button again to turn the unit off

4. Turn the unit On

5. You can see ‘’Diag mode’’ on the display , then if no problem it would show ‘’SP Wire’’

6. Turn the unit off and connect all SP Wires

7. Turn the unit on , to check the Sound and Video from the unit

If the Diag Mode comes again and again then your receiver needs to be checked by an Onkyo Service Point.

With best regards
Kind regards
