I have P.A. HMR280. once I connect the Left speaker wires, the protecion mode get in. What's the solution please ? I alreay tried to switch the speakers but got the same simptom. right ch' works fine.

The amplifier is in the passenger side rear quarter panel.

Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

Hi, Look at you speaker connections there is a short in 1 of them. That is why the protecion mode is on.

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.

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

Please let me know if you have any questions, and thanks for using FixYa.

The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

the audio source's output should connect to the inputs of the TS-WX11. caution on power supply connection: don't reverse the polarity of the positive and the negative wires.
Remember also to set your HU's output in order for it to work. If it does not work yet please give the details on your HU and other devices being used.

Can I assume the calibration procedure also didn't work for the Front left channel? (It's not a "surround" if it's in the front). Switch the receiver to Stereo mode to eliminate any DSP actions. Tune an FM station to eliminate any external device or cable issues. What do you hear from the two Front speakers?

OK? Select a DSP surround mode. Check all modes. What happens?

If the channel goes dead using some or all DSP modes there's probably something wrong with the processor. If they all work...

Isolate the source that exhibits the problem.

It was a bad left channel cable somewhere, wasn't it?
