Well I have an Onyyo TS SV515 Pro II receiver that is quite a few years old. I have lived in several houses and have moved it with me. For as long as I can remember it has been going into 'protect mode' when I turned it over 6 on the volume knob. I have a subwoofer and 4 infinite speakers and a yamaha center channel speaker.
I got on the internet the today to see if I could figure out why it did this. One person suggested cutting my speaker wires and resplicing it making sure no hanging wires where there.
I had been using the same speaker wire since I puchased it (10 yrs ago). I feel pretty stupid, cause I just did the wires to my front 2 Infinite speakers and WaLa...It works flawlessly. I can now turn up my receiver...after 10 years of dealing with no 'full' volume.
*****Check those speaker connection, they are the key*****

Power problem


If the protect function works but is causing you problems, cancelling the protection function should help, and it will be possible to enter the self-diagnostic function mode. This should disable all functions of the protection mode, excluding the 'excess electrical current detection' feature.

While pressing the "Tone Control" and "Info" keys, try pressing the power key to turn on the power. Keep pressing those 2 keys for 3 seconds longer.

this should activate the Self Diagnostic function, with your Protection Mode disabled.

in this mode the 'sleep' section on the tv's fluorescent display flashes to indicate that the mode is properly activated.

just be very aware, this function is normally there as a safety feature and i cant guarantee that disabling it altogether won't cause other problems down the road. best of luck!

The word PROTECTin display


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Sony receiver STR-AV460 stuck in standby mode and don't have remote to change it. Not sure how in got switched to standby mode, but need to get it out of this mode.


Try to unplug the AC cable from the wall for a while. However this may erase some recent programming, despite Sony AV receivers have memory enough to keep programs. Hope this may help.

ITS ON STANDBY MODE & NOT ABLE TO GET ITS DISPLAY


Try this, not sure if the same would work for ya.

Swich off the amplifier.
Prior to the process check the wires connecting the speakers are not creating a short circuit which is apparently putting the amplified into a standy mode.

1. Press the "A" "B" and power key all at the same time and hold on to it.
2. The amp will go into a reset mode and will keep blinking till it gives a normal "click" sound and the amp turns on.
3. this process would take about 2 - 3 minutes.
4. You may then release the buttons.
5. If it goes into a standby mode again and does not power on, or the standby keeps blinking, get assistance from the engineer.
6. Once it is on, you shall need to do the resetting of alll the configurations done earlier.

Hope it works, it costed me 3k to get the job done.

The receiver is connected via an Optical audio cable to my Bell ExpressVu HD receiver, When watching HD programming the Dolby Digital breaks up, I then have to switch to "virtual" setting to get sound. I...


my rule is to always install an analog connection to any device along with a digital connection as a "backup", if you will. set the input on the receiver to auto and the rest is like magic with functional equipment. sometimes digital signals do flutter and become intermittent. the receiver will then switch to analog to keep the game goin.

Receiver keeps turning on and off also the standby mode blinks


The receiver is going into "protect" mode. This means that a problem has been detected and the unit shut down to prevent further damage. Without seeing the unit and taking some internal measurements, it is difficult to provide a complete solution. Typically, the output transistors fail which can cause this. There are other possibilities too. I would suggest that you get a detailed repair estimate from a local shop. With that information, we may be able to walk you through the actual repair.
