I have never had any problems with this reciever. I just got back from a two week trip. I had left the standby power on. I now only have the amber standby light on and I cant turn the damn thing on. I have tried unplugging it and waiting a few minutes. Most times I have gotten no change. A couple of time the power came on for a minute and then shuts off. I have also tried the master reset by holding down the mode select button for 3 seconds. This does nothing also. If you have any insight please let me know. I bought this reciever a year and a half ago and am not ready to reinvest in another. Thank you.

Re: Amber light only
You really may not have a choice in this matter of buying a new one, Unless you want to invest about what it would cost you to have your unit looked at? There are no parts you can change, as its a solid state unit and all parts are soldered into place and also you have to know how to troubleshoot solid state electronics.. My first guess would be a problem with the power supply.. Its probably one of the switched supplys thats bad. Unless you know how to use a multi-meter and the workings of the soliod state regulator circuits, your gonna have to take this unit in to get an estimate.. Good LUck

Most likely, you have DC Offset(a bad amplifier). The unit is shutting down to protect your speaker system, as well as protect the unit from any further damage. If you require more assistance, or would like to inquire about repairing your Onkyo, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.
Disconnect ALL of the speaker wires from the back. Turn it on again, if it still trips, then the unit needs to be repaired. If it does not trip with no speaker wires connected, turn it back off, connect 1 speaker at a time and turn it on, when it does trip, that speaker that you just put on has a short somewhere, it could the be the wire or in the speaker.
I am experiencing a simular problem; amber light stays on ; no other lighting appears. this occured after leaving the avr in standby mode for a long time. I even tried to reset the unit as stated in the last page of manual after the trouble shooting advice - still no response - good luck!
I have the same problem. my sandby light is on but my receiver will not turn on! I checked my power going into the power supply board that was good. But i do not have power going to the transformer or the receptacle. And both of my fuses r good. check ur fuses and go from there . If u know how to get a power supply. please let me know.
I have done an update in the past/ ONE Thing/ you do not attempt to do an update at the same time you download the firmware update.
You always download the update/ Open/ Read the instruction and follow them as directed.
An Yes/ it is possible that you might be doomed/ but I would go back/ Download the update with out being connected to the reciever/ Open the download/ Make a folder for it to uncompresse to. Choose that folder when prompted as to where it is sent when uncompressing.
Then go to that folder and READ EVERYTHING FIRST. There is a folder in there that is named to read first.
Once you have read it/ you will see that it is easy to do/ and see your mistake.
I believe that if you try it again, (even though your reciever info is screwed up) it will take the full update.
Sorry about the caps/ I am not trying to yell or what every they say about caps. It just is really important to read everything first. If you don't think you understand what you read/ Read it untill you do understand it. Do more research until you do.
If the unit will not leave standby I would remove all power, disconnect *all* connections at the back, reconnect to a power source and try powering on. This will eliminate any connection causing the Onkyo to stay in standby due to a short. If it still will not enter power-on mode, you may want to look at the power source (is it properly grounded?), but beyond that the unit probably needs to go back.
All of the Denon recievers I have repaired (over 100) that shut down after a very short time are going into protect mode. The display lights up and after about 10 seconds the display goes out and the standby led blinks red.
I have found that they have one of 3 possible problems and they all require that the reciever be taken apart and fixed at component level. No way to tell what your problem is until it gets put on a bench and troubleshot.
Problem 1. This is the most common problem. One of the front channels shorts out. On the big heat sink the front channels are at each end. It is the front left channel (close to the display) This requires that the output transistors be replaced as well as some driver transistors and some resistors and a capacitor. Lots of work for a blown channel. Denon has put out a bullitin to upgrade the bias transistor and change a couple of resistors to help compensate for this failure. That channel overheats more than any other channel.
Problem 2. There is a resistor that is right next to the preamp board that opens up. It is a 10 ohm 1 watt resistor and when it opens, it causes the unit to go into protect.
Problem 3. The +12 volt regulator fails. It is in the power supply area on a smal heat sink right next to the -12 volt regulator. Generic part number is KIA7812 It also causes the unit to go into protect.
Most decent repair shops can fix these from about $120 up to about $200. Depending on which problem it is and how fast they are at finding the problem. Most charge labor by the hour.
