Re: denon avr 2803
The unit is in protect mode. This effectively shuts off the output amplifier section. This happens because a problme is detected in the output section. This unit will require service. Most likely the output transistors have failed. Figure on $20-$40 for parts plus the local labor rate for repair cost.

Looking at the user guide it appears that the amp has a standby mode.
See not below on turning standby on. Question can you see the standby light flashing.
I would also suggest using function on the amp to remove any possible issues with the remote.
One would expect the system to return to normal operation by pressing the power button again. If not what do you see on the display.
Press 1 to turn on the receiver.You can also turn on the receiver using 1 on the remote control. When you turn off the receiver, press 1 again. "STANDBY" flashes on the display panel. Do not disconnect the AC power cord (mains lead) while "STANDBY" is flashing. This may cause a malfunction.
Hi Zach, you can try the following reset as this might be a glitch in the processor.
To do the reset you need to turn the receiver on, then on the front panel of the receiver press and hold the "VCR/DVR" button while doing that press the "STANDBY/ON" button.You will see the word "Clear" in the display screen and the receiver will go into standby mode.PLEASE UNDERSTAND THAT YOU WILL LOSE ALL YOUR AUDIO & VIDEO ASSIGNMENTS ON THE RECEIVER PLUS YOU WILL LOSE ALL YOUR SPEAKER CONFIGURATIONS, SPEAKER DISTANCE AND ALL LEVEL CALIBRATION SETTINGS.YOU WILL ALSO LOSE ANY PROGRAMMED RADIO STATIONS IN MEMORY.Once the receiver goes into standby mode turn it back on and go thru the setup menu for all custom settings., Thanks, JT
Save the information currently stored in your Denon receiver, such as device commands and multi-zone controls. Some Denon receivers can control multiple rooms and each room needs to be setup properly to provide the correct controls. If the receiver was installed professionally it may be best to contact the installer before resetting the device.
Press the "Power" button or the "On/ Standby" button to shut off the receiver. On some receivers it is best to press the button on the device instead of the remote as the remote will normally put the receiver in standby mode. Ensure the display and all other lights on the device are off. Do not unplug the Denon receiver as it will not reset.
Press the "Power" button and at the same time press two buttons on the front panel, which are determined by the model Denon you own. Most receivers identify the two buttons inside the user's manual, while some older Denon receivers require you contact Denon for the right button combination. For example, some Denon models require the "Standard" and "DSP Simulation" buttons to be pressed simultaneously.
The display will start flashing at about one second intervals. Release the two buttons. Turn on the receiver by pressing the "Power" or the "On/ Standby" button to verify the previous settings and saved radio stations have been erased. If the interface does not flash, the reset was not complete and needs to be re-done. Re-enter the previous settings to ensure there are no further issues with the receiver.
The Flashing Standby light indicates a short in in the system, check speaker wires for shorts, if okay! the problem is the audio output semiconductors, because of the complexity you will need a professional to assess.
It looks like this is a common problem with a lot of the Sherwood Receivers. I've had the same problem with my R-125RDS for a while now. Finally hit on solution today by replacing a power transistor. The transistor in question is not on the power amp board but instead screwed to the chassis and wired to the mainboard. I believe it is part of the output short protection circuit. In my case the component was a 2SD2059 (silicon NPN 100V,5A) replaced by equivalent 2SD1407. The transistor seems to run pretty warm so I guess this is why they ultimately fail after a few years.
The flashing indication is telling you to seek professional help. You have have a short circuit in your output stage and your Onkyo is going into protection mode to prevent further damage. The least you can do is to switch off speaker A and B and try switching on the Receiver. If the then the system turns on you have an external shorting in the speaker wire or speaker itself.
Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure. Protect mode can result from speaker wires touching each other or the Amps metal case. Check that first. It can also be caused by unstable ohm loads if too many speakers are connected to any of the outputs especially zone 2. If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.
Your receiver is basically going into protect mode.
The SR 605 contains a microcomputer for signal processing and control functions. In an unlikely event, it may cause it to lock up. Unplug the power cord from the wall outlet, wait for 10 to15 seconds and then plug it back again.
Please also check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Take out all the wire and put them back again if necessary.. Some times even a little tiny frayed wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit. Just check your speaker as well....whether they play all right thru another receiver or amplifier. its posiible they might be shorting inside. A little frayed wire could also trigger the protect circuit in your receiver. I hope this should solve your problem. If you still can’t resolve the issue yourself, try resetting
the AV receiver/AV amplifier before going on to opening the Receiver.
To reset the Receiver to its factory defaults, turn it on and, while holding the [VCR/DVR] button, press the [STANDBY/ON] button. "Clear" will appear on the display and the Receiver will enter Standby mode. (note that resetting your receiver will delete your custom settings as well as your radio presets).
If everything else seems all right and still your receiver shut down when you raise the volume then it possible that there are bad connections on the main board that are set in.
This would generally happen if the system is slighly old or have dry solder and when you raise up the volume. This should be a simple repair that will not require parts. If you can solder, you will be able to repair this yourself. If not, then a local service center will change the local labor rate.
Hope you can sort out your problem with the above trouble shooting. Let me know if I can guide you further. Best of luck. Thanks for using FixYa!
I just got off the phone with what used to be Norcent....they are no longer in business, and do not know how or when they may be able to provide support to those of us that spent our hard-earned money on the garbage they sell. I have a LT 3222 and it lasted alittle over a year, not the picture is red and white. I called today to try to get some troubleshooting advise on the unit...only to be told that they went out of business last week. Sorry I did not have more info
Sounds like you have an issue with your electrical circuit. Your receiver could be receiving spikes of current from the electrical wiring in your house.
Review your current electrical situation. Keep in mind that certain outlets are on the same circuit and that running multiple, high-wattage devices on the same circuit can cause issues with some of those devices. Especially when it comes to turning devices on and off.
Many devices take a sudden, rapid charge to power their circuitry the moment you turn the device on. Home audio and HVAC systems are particularly notorious for doing this. Other devices on the same circuit can sometimes suffer influxes of power flow and may either turn off or go into standby mode to protect themselves from the resulting surges.
I've lost audio systems that way... I lived in an apartment building that has wiring most likely dating back into the 40's. I once turned on a space heater on it's max 1500 watt setting and blew my Logitech Z-680 speakers. (The "BOOM" sound that emitted from my subwoofer was AMAZING. I had just blown an amp circuit. It literally exploded inside of the subwoofer. Took pics and everything.)
If you have the means to do so... You might consider re-wiring your electrical circuit. Take into consideration where you're going to run certain devices and wire the system accordingly.
In the meantime, you would want to be sure to buy a HIGH-QUALITY surge protector for the audio system. Spend a few bucks and get a GOOD one with a good warranty on it. Don't use those cheapy ones that we only really use to split the outlet. NOTHING under 1,000 joules.
My receiver sometimes locks itself like that, though. If we have a power outage or the unit is unplugged suddenly, it will keep itself in standby mode until you unplug it, press the power button a few times to discharge any current left in the capacitors and plug it back in normally. Only then will it turn on again.
