SOURCE: Amp Protection Mode

no, your output transistors maybe 2 of them are gone or the small power supply that feeds the other circuitry has become defective.

SOURCE: A-SV210 on protect mode

In a generic sense I would check all the speakers to make sure theyre connected at BOTH ends.

I'm not sure who makes your receiver but if I did, I might be able to give more input.

SOURCE: my onkyo receiver (tx8511) keeps going to protect

Hi there
To answer your question;
Your amplifier goes into protect mode when it detects a fault or condition that could damage the speakers and/or the output stage.
Often caused by shorted outputs.
Although this does`nt tell you much on how to fix this problem, the best help i can give you at this point is to tell you to have it looked at by a repair shop.
Hope this help good luck

There are actually FIVE cigarette lighter/ Auxilliary Power Outlets shown in the wiring diagrams for your vehicle.
The Instrument Panel [1] Accessory Power Outlet (Cigarette Lighter) is protected by the "LTR" Fuse (# 53 - 20 Amp) in the Power Distribution Center (PDC) in the engine compartment.

The Instrument Panel [2] Accessory Power Outlet is protected by the "AUX PWR" Fuse (20 Amp) In the Instrument Panel Fuse Block on the left side of the dash.

The Center Seat Accessory Power Outlet and the (two) Center Console Power Outlets are protected by the "AUX PWR 2" Fuse (20 Amp) In the Instrument Panel Fuse Block on the left side of the dash. NOTE: If your vehicle is not equipped with the Center Seat Accessory Power Outlet, or the Custom Floor Console (optional), this fuse position will most likely be empty.

We were running a small show on the system, it was not loud. Throughout the night the protect button came on, but then we made some adjustments and restarted the system. Then it went into protect mode and...


Yes, take it to a repair shop.

You have a failure either in the power supply or one of the power amps. There is likely to be burned component(s) that are not user serviceable.

These things are a bear to work on... Mine failed again and I dread having to work on it.

The protect monitors power supply current drain of the switcher and the power amp balance.

DO NOT USE IT till it is repaired. Continued use or fuse replacement will likely do additional damage.

My amplifier turned off while playing and wont turn on at all now


Hello, it sounds like you shorted the outputs of your amp or the power supply mosfets shorted. Very common when people have the music at a loud volume. Does the protect light come on? If not then the power supply is probably shorted not letting the protect circuit get any voltage. Some amps do this and other amps if the power supply shorts have the protect cicuit built in such a way that if the power supply shorts out the protect circuit still works. Cause you checked all wiring and redid it and no fuses blew then this is your problem. I repair amps everyday for a living. ?Most of my out of state customers are from fixya.com. I'm the cheapest amp repair business you'll find. If interested send me a private message letting me know what kind of amp it is, name and model number, and i'll get you back up and running with warranty.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_b53a7494531bf96d

I would like to know if I can power my hottub right to an existing 220 line the tub runs 220 volts 36 amps and I have a 40 amp fuse already installed in the house plug


Check your local codes, you probably will need a ground fault current interrupting breaker(GFCI). Do not skip the codes, if anything goes wrong, your insurance company will not cover. Putting a special box GFCI protected will give you extra protected outlets for outside use.

Blow right speaker channel - ONKYO TX-SR506


There is some way to change a protection (fuse?). No. The fuse usually was not broken. How long did your amp turn on?
3 seconds (DC protect) OR immediately shut down (Over Current protect)? How to confirm?
1.Unplug the amp.
2.Remove the metal cover.
3.You will see a long vertically installed pre-amp board mounted next to those large power transistors fixed by 12 screws on a large aluminium heat sink.
4.Remove this long vertically installed board mounted by 2 screws.
5.With 2 screws removed, just pulling this board out and hold it with one hand.
6.Plug the amp and switch it on.
7.If your amp stays ON forever, the problem is from this long board.
8.If switch off at once, the problem is from power amp board.
Try the above- mentioned steps. I will tell you what to do next. Just search you tube for SR600 cap replacement. I have written an email here. Write an email to me if you want to fix this amp.

Fuse size?


i'd say use a small value, such as 5 amp or less. did you wire this up yourself? most stuff like this comes with an in-line fuse already built into the red power wire. in that case you wouldn't need to have additional fusing.
