Just inside the unit your power cord goes into a blackbox (like a coil of wire) that regulates the actual power the unit recieves, this maybe faulty and needs to be replaced but if this unit is out of warranty this maybe more expencive than a new one, the unit will still stay in standby but when you try to turn it on it draws more power and the supply control won't let it. I have had one of these units that has had the same problem in my work and it proved to dear to repair. Sorry hope this helped. You could try bypassing it but you would probably blow the unit up.

I have a Sherwood RD-6405 receiver and when I turn it on from standby to on, it stays on for about 5 sec and then turns back to standby automatically. I found out on the net that it could be due to a


If electronics were that easy, I would nit have had a job for all these years. To do a correct diagnose, I usually have to hook up some extra tools, like a multimeter and / or an oscilloscope A sound generator, to check the amplifier and so on. But in the receivers you can find lots of causes, why a security kicks in.
I don't think it will be possible to repair this over some e-mails or messages here. You really need a repair engineer for this. Sorry.

Standby light won't turn off on receiver r 840. Tried doing what manual says and turn off autostandby mode but still light stays on. ...how do you turn off ? i have tried everything..or does it always stay...


"Standby" means the unit has wall power but is not yet turned ON by you. When you turn the unit ON, the Standby light should extinguish and other signs of life should be evident.

It is basically an indicator that there is potential life in the unit. If it ever truly turns OFF, that is a problem.

When I turn the unit on, it turns off in a few seconds. There is a flashing standby light.


Power switch relay needs replaced. Its a small black box with a clear piece that comes off, it would be hard to replace yourself.

After few sec when you turn on your receiver did you hear a click noise ? if yes your receiver is OK not in protection mode if no click noise is output protection in that case you must return where did you buy for service and update firmware a lot of update
However you can reset your receiver and debug the DSP section ( digital signal processor ) as follow

2. After " Clear " is displayed, the preset memory and each mode stored in the memory are initialized and will
return to the factory settings, and turn to Standby mode.
Now turn back on and check if it work or not and make sure check input mode such as analog or coaxial or optical input if stil no sound then debug DSP as follow
To set in DSP debug mode
1. Press and hold down DISPLAY button, then press STANDBY/ON button while the unit is powered ON.
The version number of m icroprocessor is displayed only for 3 seconds.
Main:
8 1.05/07903A
2. Press TONE+ button within 3 seconds above, the version number of 1st DSP is displayed.
DSP 1st:
SR8051:07601A
3. Press DISPLAY button while the 1st DSP version is displayed. The status of DSP and DIR will be displayed.
E1A48K0N/0FFPo
FFFFFF0 0 000
To exit
Press STANDBY/ON button.
Then unplug the unit for 30 sec then plug in it should work now if not you need to return it to 1 of the service center Onkyo in your town to repair it

Going into protect due to either blown channel or probably a 15v regulator might be down which I have seen many times also. causing unit to go into protect.
