Question about Yamaha HTR-5890 Receiver

1 Answer

No Power The unit has worked fine for 6mths then just would'nt power up. I have voltage coming in and the two fuses are good. I dont hear any stanby click and no lights indicating voltage. Are there any fuses other than the two near the power cord or any thing else that I can try?

    I have the exact same problem with my receiever. I bought it 4 months ago and haven't used it for about a month. It worked fine a month ago when I used it last and for the previous 3 months. When I hit the power button it clicks but nothing happens. None of the fuses are blown that I could see. Any thoughts?

In your power board near the back of transformer you have a backup power source of 5volts. that is for the cpu and the power relay swicth. can you check if you have that 5volts present. What i can see only in your unit is a major brekadown of your main amp section, all power transistros must be busted/shorted, and no chance even for a click on the relay. that is also feature of the protection. you wont be able to get the unit started even for a while. the fuses for yamaha do not normally blow and very often only your protection circuits enables. but in your case it is a very bad output stage now that you dont even get the display on to see the trouble in the built in diagnosis.

I have a Yamaha htr-3065 HDMI receiver that won't turn on after we experienced a power outage. When I plug the unit in I get a buzz sound from transformer but still won't come on. The fuse and power supply...


If you have any electronics experience you should check the diodes or the bridge rectifier in the power circuit. Look for burned components or bulged capacitors.!!!Always unplug the unit and wait a few minutes before attempting any procedure!! I have found that capacitors usually fail due to voltage spikes which can happen when power is reinstated after an outage. Always use surge protectors on electronic devices. They have a component called an MOV that will absorb voltage spikes and save your equipment.

Does not come on at all have chec:ked fuse in plug ,was working perfect just stop playing 18 mnths old joyce-colathotmail.com


There will be additional fuses inside the unit.
Check to see if there is voltage coming out of the transformer. If there's none, look for fuses going into the transformer from the power input.
If there's voltage coming out of the transformer, check the fuses between it and the main board.
If you replace the fuse, and it blows again, don't try this a second time, the unit needs to be serviced by a qualified technician as there is something seriously wrong.

There is a small glass automotive fuse that is located inside the unit next to where the power comes into the unit. You can check this fuse to make sure that it is not blown. If the fuse is blown, you can replace it. But chances are that it will blow again. But sometimes it will work for a long while.

My Pioneer VSX-517 receiver will not power up. Have checked power cord & fuse.


good start. the next is to chech standby voltage 5 volt, that goes to the microprocessor which will enable you to turn-on the main relay(12 volt)that powers up the whole unit. so if you cannot hear a click when you push the power button the the standby transformer capacitor and the 5 volt needs to verified. if this is good the relay - 12 volt and if this is also good the micro is bad. oops-hope it doesnt come to that. the micro is located on the circuit board mounted on the faceplat-a large many pins IC.

Onkyo ht-r670 receiver is new and will not turn on. red standby light is on. but no display. also remote doesn't have any effect.


I would check any fuses first. The power transformer could also be open.There is a stanby supply that provides 5 volts that is always on . This is what supplys voltage for the standby light and the cpu. When you press the power button the cpu trips the power on relay that provides the 120v ac to the main transformer. If the transformer is open nothing happens. Onkyp part # is 2301798. Check the windings for continuity.

Hello, My receiver wont come out of


If you push the power button and you hear it "click" that means it's getting power. Now, that being said... Couple things to check: first: disconnect all speaker wires at the receiver and attempt to power up, if it does, that's a good sign that your receiver is ok and your problem lies in the speakers or in the speaker wire. If you still can't get it to power up, pop the top of the unit. Most receiver's have 6 or 7 #1 phillips head screws on the sides and rear of the receiver. Pull these off. Look directly at the area where the power cord plugs into the unit (make sure the unit is unpluggged) There is usually a fuse right nearby. If it's a white fuse or gray fuse you may need to do a quick continuity check with a meter to test. If your familliar with meter's, just switch it to continuity/tone. If the fuse is good, you will hear a tone from the meter. If not, there's your problem. If your not sure how to test with a meter, either take it to Radio Shack or similar store, ACE hardware etc. they can test it for you and will generally have replacements in stock. If the fuse is good, your speakers are disconnected and you still have no turn on, your receiver needs to be serviced. If that's the case, whether you service or replace the receiver, get a good "Theater" line conditioning surge!!! like Panamax, Monster, APC, or Furman. A good unit will start around 250. Small price to pay for saving expensive electronics! Hope this helps. If you need further help, just post a comment and I will be glad to help.

Power wont come on at all


May be the power supply check for power to the power supply and the output voltage from it as well !! May need to be replaced ! It cost $125.00 for part and $225.00 for a new one installed !!

Help required for dumbo on Amps Denon AVR 2808CI


Your unit was probably damaged in shipping. Denon is a nice unit! Do you hear any clicks when you hit the power button??? You should hear two relay clicks. You should hear the power relay click at power on and 3 to 5 seconds later you should hear the speaker protection relay click if your audio amp section is ok. If you hear both relays click then your display circuit is at fault. Open the unit and look for breaks on the front pcb (behind the display) and on the main board in the power section ( where the fuses are ).
Good Luck!

Unit won't power up completely


The clicks you hear are the relay that completes the circuit for 110V AC to the main power transformer. Mine had the same problem and here's how I've gotten it to work. A lightning strike near our house caused it to fail, and I traced it to the power transformer relay activation circuit. The tuner and amp were fine. I found a bad transistor in the relay circuit, but didn't have a replacement on hand, so I soldered a jumper wire across the relay switch connections on the power transformer circuit board. This connects the 110V AC directly to the power transformer. DC Power to the amp and tuner circuits will still be controlled by the power switch, but the transformer will be supplying all the AC voltages to the main board. If there is a real problem with the circuits that load the transformer or the transformer itself, then the fuse will blow. If the fuse doesn't blow then I suspect the problem is just in the power sequencing circuit itself, that is not needed for operation other than to make the unit "Energy Star Compliant". A lot of electronic items have a transformer that is not switched, and only fused, so that the supplies are available at all times.
