Question about Yamaha Yht-s400 Home Theater System Black

1 Answer

My unit turns off by itself

I thought the problem was the speakers, so I disconnected the speaker cables and left the unit running.. It turned off after about 2 minutes. I can turn it back on, but it shuts off again.

See if there is a Factory or Return to Default procedure in your owner's manual. If that doesn't take care of the issue, your unit has a condition known as DC Offset, meaning a damaged amplifier. For more information, please visit my website at audioserviceclinic.com. You may contact me directly through the website.

SOURCE: my yamaha DVX-200 turns itself off after 2

It would appear there is something internally amiss. Take it to a Pro who can engage his Mk.I eyeball and isolate the fault.

No volume on all left side speakers


Determining the Cause of the Problem Let's assume our system has a head unit, a crossover, a two channel amplifier and two door speakers with only the right speaker working (the left speaker is not working). If the door speakers are behind the door panels then we want to make sure the speaker is the problem before removing the panel. We'll work backwards starting with the amplifier and ending at the head unit. Testing for a Speaker Problem With the vehicle and the stereo turned off disconnect the speaker wires for both the left and right speakers at the amplifier. Now connect the left speaker to the right amplifier output (which we know works). Turn on the stereo system and make sure the balance is set to the middle position.If the speaker still doesn't work then the problem is somewhere between the amplifier and the speaker Testing for an Amplifier Problem Now we'll need to see if the amplifier channel is bad. Put the left speaker back on the left amplifier channel and the right speaker on the right amplifier channel. This returns the speaker wiring to its original configuration. Again, with the vehicle and stereo off unplug the RCA cables from the amplifier's input and switch them so the left cable is in the right input and vice versa. Turn on the stereo system. Testing for an RCA Cable Problem For any intermediate components between the amplifier and the head unit follow these steps for each one. We only have a crossover so we'll just do this once. Begin by testing the RCA cables between the intermediate component and the amplifier. Unplug both RCA cables from the intermediate component's output. Now plug the working channel's RCA cable into the non-working side of the crossover. In our case the working channel is the right so plug the right RCA cable from the amplifier into the left side of the crossover. Turn on the stereo system.
If the right channel continues to work then you know the problem is in the RCA cables between the amp and the crossover. esting for a Crossover or Equalizer Problem At the input of the intermediate component (in our case the crossover) flip the RCA cables around (left to right input and vice versa). Turn on the stereo system.
If the right channel continues to work and the left channel continues to not work then you know the problem is in the intermediate component. Replace or repair this component.
If the problem is now in the right speaker and the left speaker works then the problem lies before the crossover. Turn off the stereo system and return the RCA cables to their normal places.
Testing for a Head Unit or RCA Cable Problem Pull out the head unit from the dash so you can access the RCA cables. Unplug both RCA cables from the head unit. Do not disconnect any other wiring. Plug the right RCA cable into the left channel of the head unit. Turn on the stereo system.

I have this issue, my teac ag d7900 which itself off to standby and when I switch it "on" again, it says protect and shut itself down again


Right. This means that either you have a short in your speaker cable somewhere or the short-detector circuitry inside has problems. Disconnect all speaker cables and turn the receiver on. If the symptom goes away, turn the receiver off again and connect one of the speaker wires. Repeat until it starts to go into protect again. When it does, the last speaker you hooked up has a short somewhere in the wire.
If protect always comes on, you'll need to get the unit serviced.

I have an RXV-667. It is approximately one month old. It will turn itself off automatically after a few hours of use. The auto shut down feature is set for 8 hours and it has never been on that long. All...


But is it getting hot?


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.

Just for GP, disable the auto shut down.

It can be either problem with the receiver itself, cables or your speakers. You can try different combinations to narrow down the issue.
1) Also the radio does not work?

2) Try to run the Test tone to the speakers (Setup / Speaker setup / Manual setup / Test tone). If you hear the tone, then the issue is configuration problem with your inputs.

3) If possible, try to connect headphones to the receiver. If that works, it can be issue with cables/speakers or their setup.

4) Try to run the Automatic Speaker setup with YPAO microphone. It will eventually fail, but will provide you error code, which you can lookup in the manual for different reasons.

5) Try disconnecting all the cables and reconnecting them again, possible trying left speaker with right cable and right speaker with left cable.

When i turn on my receiver, it starts up for a second and then it turns itself off. thoughts?


first of all , check all your speaker wiring make sure none are touching acrros(frayed) . if good disconnect 1 speaker at a time and turn on unit . if it stys on you found your problem- a shorted speaker.
If none of these things work, disconnected all speaker aand check with a volt ohm meter( you can get a cheapie at Radio Shack)- acroos each speaker you should have either 4ohms, 6 ohms or 8 ohms, depending on the rating on the back of the speaker. if any read lower, replace speaker.

If all else fails, go to yamaha.com/usa and go to support, call service center for repair listed on site.
hope this helps ! Steve A.

Sony cdx m610 resets itself at half volume


You have a shorted speaker or speaker wire. If a wire is touching metal lightly it may not have full continuity (short) and will work until more voltage (volume) is sent to the speaker and causes the short. Disconnect all speakers at the radio then turn the unit back on. Turn up the volume and see if it cuts out. If it stays on, re-connect speakers one at a time and test. Once you find the problem speaker, disconnect the wire at the speaker then test again. This will eliminate the speaker itself as the problem. Test again. If it still shorts, trace the wire from dash to speaker and look for a cut in the sheathing exposing the wire. Repair or replace the wire and you should be good to go. If the unit cuts out with all speakers disconnected, the problem is internal and will need to be serviced. Before you repair/ or replace the unit either check all the wiring and the speakers or have someone do it for you so it does not give you a repeat performance. Hope this helps.
