20 Most Recent Yamaha HTR-5790 Receiver Questions & Answers

found the source of the problem with "Check SP Wires"! to solve it is necessary to check each speaker connected to the device Yamaha on the rear panel (red and black) using the device for determining the number of ohms, which shall not be less than 4 ohms, in large passive speakers experienced in Amfitone AU-027, the result showed that left at 0.45 (7) ohms, and the right-hand column, as such, no.
The successful test ... and good music!

I had the same problem (though the unit may still work even in this Internal error state, except the tuner - try it) and my technician friend advised me to replace the HDMI I/O Card inside the unit. However the card cost is more than a hundred dollars while another brand new unit only costs around USD170 in ebay. That gave me a better option to buy a new unit but seems this Yamaha unit is a dud which could be the reason the unit production was discontinued.

Try hooking up the Spkrs sometimes if there is no load the override will shut the unit down so things don't blow.

Hi,


Yes, you would need an iPod to RCA Cable that will connect to your iPod and to the RCA Auxilliary input of the Yamaha HTR-5790 7.1 Channels Receiver. Similar to a Cygnett Groove Transit - MP3 Phone to RCA Stereo Cable or an iPod to RCA Retractable Cable.


Good luck and kind regards.

Hi,
On the back of the Receiver plenty of "RCA inputs" ..you can use any of it except
"Phone /turntable" input and than select it from control knob the relevant input..
Take care and pls remember to rate me..
Thanks

You have a speaker wire that's either touching the other post on the back of the receiver or a bad speaker or a bad wire. Check all your wiring and all will be well again. If you need more help, post a comment and I can help you further. Hope this helps

WOW this worked.. Hold down the ABCDE and the preset tuning right arrow and then hit power.. It puts it into a diagnostic mode, but it stays on.. I just rerouted my video to not use the receiver  and the audio works perfectly now. 

Protection mode is there to prevent your receiver from overheating to the point of failure. Try this. Make sure it is ventilated real well. Put it by itself. Don't stack anything on top of it. Even if it has a fan I us a little fan behind my receiver to circulate that warm air off of it. This works real well. Make sure your receiver is setting on a nice hard surface too. Not carpet or anything shaggy like that. Receivers and amplifiers will go into protect if they are rode real hard. Keeping it as cool as you can will minimize this. You can also turn the bass and or gain down on it a bit every now and again to help it cool a little bit. That receiver has final transistors in it that get war as power increases along with the time it is increased. Keep it cool and your it will stay out of protection mode.

The remote for your unit is the RAV-238. You can purchase a replacement here:

Generally speaking, an amp protects itself from heat, shorts and overloads 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 as a root cause for intermittent shutdown.

You could follow its recommendations. Make sure they're not shorted and are tight.
