Question about Yamaha HTR-5940 Receiver

2 Answers

My yamaha receiver shuts down when I turn it up.

I have already checked speakers and they appear to all be functioning properly.I have connected using GE Ultra wire (16 gauge). I was wondering if I would go to a 10 gauge wire if this could solve my problem?
Your help would be appreciated ,
Terry

After checking the speaker connections as suggested and finding them in order, check that you have properly matched the impedance of your speakers with the receiver. Here is the sequence for doing that:

If you are to use 4 or 6 ohm speakers, set “SP
IMP.” to “6ωMIN” as follows BEFORE using this
unit.
1 Make sure this unit is set to the standby
mode.
See page 26 for details about turning on this unit or
standby mode.
2 Press and hold STRAIGHT (EFFECT) on the
front panel and then press STANDBY/ON to
turn on this unit.
This unit turns on, and the advanced setup menu
appears in the front panel display.
3 Press PROGRAM l / h buttons on the front
panel to select “SP IMP.”.
The following display appears in the front panel
display.
4 Press STRAIGHT (EFFECT) on the front
panel repeatedly to select “6ωMIN”.
The following display appears in the front panel
display.
5 Press STANDBY/ON on the front panel to
save the new setting and set this unit to the
standby mode.
The setting you made is reflected next time you turn on this unit.

If the impedance is set properly, when you adjust the volume take is easy. A quick increase in volume will change the impedance (if only for a millisecond) enough to trip the overload protection.

Good Luck.

If you have bare wire going into the receiver's output terminals, make sure a strand or two of wire is not touching the other terminal. That can short out the outputs, especially when you turn up the volume, which increases the voltage present at those terminals. That would cause the receiver to shut down as a saftey precaution.

My Yamaha RX-V563 receiver displays "Check Speaker


Look closely at the rear connector panel of the receiver and look for pieces of stray strand wire that may be touching the speaker A binding post and the receiver chassis. If you are not using strand wire connection to the binding post then check whatever connector type you are using such as banana plug or spade plug for breakage or corrosion, the same goes for the speaker cable itself which isn't always so easy to detect. A few broken strands can cause a problem.
If it is clean, turn off the receiver and disconnect the speaker cable. Check the binding post for tightness; if you can wiggle it then it is broken and needs to be replaced.

I have a yamaha, natural Sound Av receiver RX-V483, every time that i start the unit it will shut down after 5 seconds. thank you very much


It indicates an output load problem, dis-connect the speaker wires from the back of receiver. Next power on and turn the volume right down, if the unit runs, check for shorts in the speaker wires and speakers. But if it still shuts down "with speakers and wires dis-connected" one or more of the audio output ic's is shorted and will need a professional to assess the item.

I have a yamaha R-V703 receiver and it has worked well until today. It was turned up loud and all of a sudden kicked off. Now every time it is turned on and the volume knob is turned it turns the unit off....


Make sure the speakers are connected correctly. Something inside overloaded and could have blew a fuse or is in protection mode. Before taking the unit in for servicing or attempting to opening it, I suggest checking that the speaker wires are connected correctly to your receiver in the back. Even one loose strand of speaker wire touching the steel panel will shut your receiver off when the volume is turned up. If that isn't the problem, then try to unplug all the speakers and test it again to confirm that the speakers are not preventing the receiver from functioning properly. Lastly, if no success, wait a while until the unit cools then try again without speakers connected.

Yamaha rx-v456 av receiver, shut down with optica cable


Does it work without PS3 attached?
When receiver turns off, it is usually due to badly connected/configured speakers. Try powering on the receiver without speakers.

I have a new RX V661 7.1, shuts down when I turn it up.


How much loudness are you trying for. Also, the program material and bass/treble settings factor in when asking a system for increased power...accordianman

Rx-V2400 Shut Down


Hi Seems like you have a shorted output channel, remove all your speaker connections and try again, if the problem persist, good chances are that you need to replace a couple of power transistors, let me know if you need more help, I've fixed some Yamaha amplifiers with this problem Good Luck Miguel

Yamaha Receiver shutting itself down


First of all, make yourself sure about the issue that the impedance between your amp and the speakers is fine. If it is so, the problem must be caused by some blown capacitors. The main reason could be surge or something. You had better call Yamaha service, and get your amp serviced.

Get another receiver! I had the same problem and had the power supply replaced $250 and after 3 months it started doing the same thing.  I just purchased a Pinoeer Elite VSX 90TXV.
