20 Most Recent Onkyo TX-8211 Receiver Questions & Answers

The manual for the tx-8211 says that the total impedance for when you have both A and B speakers on are 8 ohms before it goes into protection mode. So look on the back of the speakers and read the impedance and add them up for that side of the speakers. You can wire them in series and it should fix them. I know this is a tad bit late by yknow two years but I’m bored and have nothing else to do.

Soldering is involved .

First check balance and fade to ensure it is getting a signal. If that's OK then check wiring.

the system protect is usually displayed when a condition of short or shorting is occurring in the speaker wiring or the voice coil of any of your speakers.... thte circuit of you reciever is trying to protect itself and you from a very costly repair,,,so it you have another set of speakers try to use them and see if the condition still exists and if it does the problem is in the output section of the receiver,,,and if the protect no longer exists you have fixed your problem,,,good luck

Check all of your speaker wires and speaker turminals. I bet there is a short.

It's unlikely you can. Most hifi shops can though.

If you're still reading, open it up, and look for a switch of some kind. It may not even exist, but I'd say it's the best thing to look for when doing something considered mediocre at hifi shops (if it was difficult and interesting, they wouldn't find it so boring). Maybe it's a button. It will probably be labelled protection or reset or something similar.

So, look for a switch, or something similar. I have no idea where it would be because I've never dismantled such a thing. The other option (if you haven't done so already) is unplug it from the power and leave it for a while (overnight may be the best bet). This may fix it for you, and it's easier than undoing all those screws.

This is a piece of **** receiver. Ive had the same problem since it was brand new.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

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 'naked'. 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.

Hi

Check the "Balance" control on your receiver amplifier.

Check all connections and cable to the inoperable exterior speaker.

1. Disconnect the "working" outdoor speaker from your receiver amplifier connection/ channel. Switch the cable from the non-operating speaker from its current connection to the working speaker connection. If the speaker now works fine, the problem is with the receiver amplifier.

2. Reconnect as original. Remove the speaker cable at the "working" speaker directly and connect it directly to the non-working speaker. If the speaker now works the problem is somewhere in the original speaker cable.

3. If the speaker still won't work then the problem is in the speaker.

Please get back to us if you have further query else please accept the suggestion.
