Hi, what the error code is telling you, NG: LCRSLSRBLBR, is that due to some output problem or power supply, the speaker outputs are not working, NG by Non Good, L by Left, C by Center, R by Right, SL by Surround Left, SR by Surround Right, BL by Back Left and BR by Back Right
I suggest you check all speaker connections, disconnect all speakers and see that this is the same, the problem is in the computer, if it does not indicate failure, then go connecting the speakers one by one until the fault appears again and in that last speaker connected, the fault could be, try all the speakers
I hope you can solve the problem, but look for a specialized technical service
Greetings Franco Dosil


Hola, lo que te esta indicando el c?digo de error, NG:LCRSLSRBLBR , es que por algun problema de salida o fuente de alimentaci?n, no est?n funcionando las salidas de parlante, NG por Non Good, L por Left, C por Center, R por Right, SL por Surround Left, SR por Surround Right, BL por Back Left y BR por Back Right
Te sugiero revises todas las conexiones de parlantes, desconecta todos los parlantes y observas que esta igual, el problema esta en el equipo, si no indica falla, entonces ve conectando de a uno los parlantes hasta que te aparezca nuevamente la falla y en ese ultimo parlante conectado, podr?a estar la falla, prueba todos los parlantes
Espero puedas resolver el problema, sino busca un servicio t?cnico especializado

To check protect mode: what kind of protection it belongs to when NG channel is displayed such:
NG:LCRSLSRBLBR
NG__CH:LCRSLSRBLBR
1.Press the Enter button
2.Protect cause are displayed for 5 seconds.
DET.PROTECT:I(overcurrent)
DET.PROTECT:V(dc detected)
If warranty still have,call onkyo to repair.
Search you tube SR600 cap replacement and send an email to me, if you want to repair it by yourself.

NG: LCRSLSRBLBR?? What is this?

Does the display show you are in protect mode , or is a light indicating that? The unit automatically switches to standby when the
"Hardware" - "Power Management" - "Auto Standby"
setting in the Setup menu functions are set. The protective circuit function may have been activated.
If this has occurred, "AMP Diag Mode" appears on the
display when the unit is turned on again, and the unit
enters diagnostic mode. If the results of the diagnosis is
that there is no problem, the "AMP Diag Mode" display
disappears and you can use the unit normally again. If
"CHECK SP WIRE" appears on the display, the speaker
cables may be short-circuited. Make sure bare speaker
wires are not touching each other or the back panel of
the unit, then turn the unit on again. If "NG" is displayed,
immediately unplug the power cord from the wall outlet
and contact your dealer.
• The protective circuit function may have been activated
because the temperature of the unit rose abnormally.
If this happens, then the power will continue to turn off
after you have turned the unit on again. Make sure the
unit has plenty of space for ventilation around it, wait for
the unit to cool down sufficiently, and then try turning it
on again. This is out of your users manual.

General suggestions are to remove all speakers and speaker wiring with unit off. Turn on and see if problem has stopped. If not, let unit cool down if warm and try again later. If problem is still there it needs repair shop work. I fht problem went away, shut off power and connect one speaker at a time and testing. Keep adding speakers one at a time with power off and see if a bad speaker or wire set can be located
