Question about Onkyo Audio Players & Recorders
I bought this AV receiver Onkyo Tx NR 525 just 3 months back form USA and took that to India. During playing the receiver it gets very hot. Suddenly without any reason it went off while playing a movie. I live at India and there is no service center of Onkyo here in India. Finding no other way I sent that to Onkyo service center, Singapore and got that back after a month. It was running well and today again the same problem, suddenly it went off and making a repeated "click" kind of sound inside the receiver. It is time consuming and costly for me to again send it to Singapore and repair. Totally frustrating performance by Onkyo,can anyone give a service manual of onkyo so that I can repair in here? Thanks
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

SOURCE: Onkyo TX-8522 stuck on standby
This is Not a real Fix, However it stops the problem!
Do not plug any power cords into the Receiver. I have found that using the "switched or unswitched" plugs in the back cause the trouble.

I have Found two problem which cause NO AUDIO 27-07-08
2.Failed componet IC Q710 part # LC372100PT
IF you disconnet CKT board NCDG-6575
you will get audio on speaker B left & right CH only
SOLUTION have CKT board NCDG-6575 Repaired or REPLACED

hi, when the unit shuts off by itself, it means that the protection circuity inside has been activated. it can be a problem with the receiver itself or it is just detecting something hooked up to it that can cause possible damage so it shuts off.
you would need to disconnect everything from the back and by itself, try to turn it on, see if it will stay on and then crank the volume way up to max. if it stays on, the receiver is ok and you then need to rehook your devices one by one starting with the speakers until you determine the one causing the receiver to shut off.
however, if the receiver shuts off and won't turn on even by itself, it means that the problem is internal and it either has to go back to your dealer for an exchange or it has to be sent to a repair center for servicing.
hope this helps a bit.. ^_^

Onkyo receivers have a safety circuit in them to protect the Amplifier from blowing up:
If you listen closely when it shuts down ( after a loud scene ) there is likely a loud 'Relay Click'..
If this is what is happening you might be able to verify it by turning the volume all the way 'off' and waiting for the circuit ro reset ( releasing the safety relays & returning power to the internal Amplifier ) : you should hear another click, yhen you can bring the volume back up carefully and there will be sound again.
This safety circuit trips when then Onkyo receiver detects an 'Over Current' condition on the
' Power Supply ' that feeds the internal 'Audio Amplifier'..
Generally caused by:
Improper load presented to the Amp outputs ( FL, LR, RL, RR, SUB, CENTER )
If you can ( one at a time ) turn off the SUB, Center, Fronts and Rears: trying to re-create the failure each time while you have one part of your system disabled or having their level turned way down..
You can isolate where the problem is coming from.
- any or all of these speakers being the wrong Impedence ( I.E. 4 Ohms instead of 8 Ohms )
Unless the receiver manual or the sticker near the 'speaker connetor' specifies a range or another value, you should assume 8 Ohms. Your speakers should say on the back of them.
- any of the speakers being connected in parallel ( 2 speakers to a single one speaker output ) .. Two 8 Ohm speakers connected in parallel make a 4 Ohm load to the amplifier.
- If the Suwoofer is Passive ( Not having its own power cord and amplifer ) it has a
Passive Crossover : this crossover can have its own power rating or limitation.. If it is constructed with capacitors that have too low of a working voltage, then they can saturate and the crossover itself can present a load to the amplifier that will case this 'Over Current Shut-Down'..
You user manual should detail this.
