I have Yamaha HTR-5890 power up issue. Switch it on and it clicks off in 2 secs

Yamaha RX V750 power on but cutoff

Page 25 discusses the minimum speaker impedance setting for expected lower-than-8-ohm loads. Running A AND B may present a load that is dangerously low. BTW: 6 is not a whole lot lower than 8.

Look at your speakers' impedance specs. Running them in parallel would present a much lower load than either pair alone.

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

You very well may have blown and amp or a speaker.

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. Eure 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

ensure your system balance is set to central.


I hope this was useful.

I have the exact same issue, except that it sometimes turns on (very rarely though)

Sounds like you have a bad amp IC or transistors.
When these go bad they almost always put roughly 40 volts dc from the amp power supply to the speaker terminals. The protection circuit senses this dangerous (to your speakers) dc voltage and disconnects the speaker terminals from the amp via internal relays (the ones you hear click) and puts it into protect mode. If it didn't the dc voltage would quickly toast the voice coils of the connected speaker.

You are probably connected to the pre-out jacks. These are not amplified. Connect them to the B speaker outputs(screw down connectors). If that won't work (and it should), you can connect to the "Presence" speaker connections(spring loaded connections).

must have the tape monitor to work the regular tape loop does not physically go back into the receivers processor.

only other solution is if the receiver has PRE out and ins use the PRE out to the EQ then back into the PRE in.

if you have the OUT but no in then the solution would be to go out of the EQ and into an external amp.

In my experience "young adults" like using EQ's to boast bass output.

If that's your goal a POWERED subwoofer is what you need.(check out polk audio direct on ebay)

Your unit is a 7.1 surround receiver the reason that it doesn't have the capability for an EQ is that it messes up the surround sound processor.

If the sound is not what you are looking for the issue more than likely is with the speakers. post a messege with what you want to achieve and I'll try to point you in the right direction.

for the past month i have been shopping for the perfect home theater system and have narrowed it down to a bose system,a sony system and a paramax p510...i have listened to all 3 systems and have found the paramax to be the better system not a cheaper system but seem more bang for my buck at 3200$,a very powerful tube amp and downfiring sub maxes out at 2000 watts...

Power supply is burned out. surge or spike got it, replace power supply unit.
