Yamaha RX-V870 receiver front right channel not working

I think I may have caused this when I arced the speaker wire pair. Is there a fuse or something I can attempt to fix the A or B right channel not working?

    I see 3 that looks like it is for the main power and then 2 on circuit board....they looked ok....I even tried to bypass them just to test and doesn't look like any of those 3 fuses I see are the problem. Are there any other fuses, or something else to test/investigate? Thanks for the help so far and any other help in troubleshooting/resolving is greatly appreciated!

There is a fuse in side the system you could try but that sounds like the channels is shorted, but yet again there could be a fuse for it

    If you see three fuses thats probly it sometimes there hidden in other components but not so much annymore, did you look at the front right channel teriminal too see any black marks, cause like i said before it could of shorted

I have a Yamaha RX-V1400 AV Receiver and would like to pair with Technics SL-1300 turntable and pair of JAMO speakers. How do I proceed?

Having looked at the manual it says you can connect the turntable via the phono jacks at the back, with the earth wire to the earth terminal. It's likely you have a magnetic cartridge that needs amplification. But if you put it into the jacks as it stands, it will soon become clear if you need a magnetic cartridge pre-amp. For if you have to really turn up the volume to hear it, then you need one. But if the deck plays at normal level to everything else then you don't.
As this is a multi channel receiver you will need more than just two speakers! You can connect the Jamo ones to the front right and left settings. If they are only 6ohms you have to set the speaker setting to 6ohms before useing them.

The unit probably has a setting to just use the front speakers if you just want to use them only. But I suspect it will have an All Channel Stereo setting you can use. Then all the speakers will work and it will give you a much bigger sound.

Left speakers do not work

As power amps are just two amps joined together all you need do is identify the left channel and compare it with the right. Ignore any parts common to both channels. The first thing to do is a visual check. If something looks broken burnt, or odd compared with the right channel then you have probably found the culprit. I suspect you could have a power output failure. It might be that the output devices are separate transistors. They might need to be replaced.
By the way just follow either the internal speaker leads or the connections to locate the right and left channels.

When right channel is wired it shorts out the power supply. Aragon 8008 when powered up without input and output, no problem. When connected with speakers and line level feed in, the left channel works...

Fuses blow when there is an overload caused by a short circuit. If the speaker you connect up to the amp causes a short. There is either a shorted part in the speaker or the wires to it are touching at some point. Assuming you can sort out the speaker issue and connecting a good speaker with good wiring and it still causes a short and blows a fuse. Then it's likely the output device(s) in the right channel have developed a short themselves. Perhaps as a result of being connected to faulty wiring or speakers.

I have an Onkyo A-7055 amd want to hook up two speakers. Looks like a dozen connectors in the back of the unit... which ones to use. If I experiment is there a chance I could blow out the unit?

Do you mean you want to connect 2 pairs of speakers, or just 2 speakers like you say in your question? There are 4 pairs of screws on the back of your amplifier on the upper right side of the rear panel near the fuse cap and the AC outlets. Each pair of screws will be connected to one speaker. Your Onkyo can be connected to 4 speakers. If you want to connect only 2 speakers, use the screws labeled "SPEAKER A" and connect the speakers to the left and right channels, and make sure you connect the + speaker wire to the screw with the red marking around it. Connect your other speakers the same way, one speaker per pair of screws.

I have 4 speaker wires, black green red white speaker left + speaker right + speaker left - speaker right - which cable goes where?

4 speaker wires, black, green, red, white ;speaker left +speaker right +speaker left -speaker right. First see what pair of speaker wires go to left the channel of the amplifier. One of each speaker must be connected to each amplifier´s channel, no matter of colors of the wires. Two wires for each speaker to each channel of the amplifier (rear panel + and -). Then you will have 4 wires connected to 2 stereo channels of your amplifier. Two wires for each speaker.

No sound to remote speakers in dining & deck areas.

Incoming from WHAT? Ampifiers accept inputs via RCA connections and send amplified audio to the speakers via the + and - OUTPUT terminals.

I'm guessing your colored wires are from your speakers and that there is a piece of this puzzle we do not see - how the speakers on the deck and in the dining area are wired.

You say, "was working ok previously"... previous to WHAT? Something changed.

You can probably troubleshoot and resolve this yourself.

Set the amp to a medium output level.

If the wires are simply leading to either or both pairs of speakers you could select any two of them and connect them to one side of the amp. Only a pair going to the same speaker(s) will produce sound. Once you identify one pair, the other pair probably goes to the other speakers. Connect them to the other channel output.

The last piece would be to establish correct phasing between the speakers. Bass response will suffer if they're not IN-phase. Play something with substantial bass. Listen closely, then reverse the wires on one side only. Test again. If it IMPROVES you have it right. If it losses bass, put the wires back the way they were.

Unit would shut down just a few seconds after startup. Checked all 5 speakers and all had good impedance. Main speaker left channel must be blown 'cause all it does is hiss. How to fix?

Your unit is likely shutting down because you have a short on one or more speaker outputs. This is a safe mode on short circuit to protect the unit.

The hiss is an indicator of the short (it has been shorted so long that one transistor set is probably bad. Look for a single strand of wire crossing from red to black speaker output on the receiver or at the speaker input on the speaker. If not there - you may have touched speaker wires together at one time - especially when volume was turned up.

Most likely you have blown the power transistor to that channel (left). You will have to open up the unit and look for the large transistors mounted to a heat sink (large aluminum frame). There should be two transistors for each channel (12 total for six channels) in an AB (push/pull) configuration.

You will have to measure the output (AC voltage) of each pair - right wire is usually the emitter. You can hold the neg (black) lead on the volt meter to the black speaker terminal when checking each. If you are lucky - there will be white lettering to indicate which speaker each pair of transistors is for.

Simply desolder the bad ones and replace with identical type ( or should have most transistors you will need - radio shack will not have the correct transistors). If you get no AC or only low AC or AC output voltage does not track with volume knob turn, then you have a bad set of transistors on that channel. Compare to other channels.

Be EXTREMELY careful when you open the unit. Static electricity can damage components. Touching something near the AC main (wall power) kinput, the filter network for AC main power, transformer, rectifier will damage you. If you are uncomfortable, you can take your time and learn how to do this (Books, videos, learn from a friend). Do not do this without knowing about electricity and where the hot spots are in your unit. You will be much better off spending $300 - $500 on a new unit rather than risking your life/health to fix this unit.

Good luck and drop a note on this site to let me know what you do.

I would like to know how to connect my Bose 901 to my Yamaha RX-V765 AV Receiver.

Ahhh, the good ole Bose 901. (I like those)... And you want to connect them to the Yamaha RX-V765 AV receiver. That should be a piece of cake. I assume you only have two Bose 901 cabinets. If so, you simply need to connect one end of your speaker wires to the terminals found on the 901 cabinets, and the other end of the speaker wires need to go to the Front Left and Front Right speaker outputs of the RX-V765. The RX-V765 is a 7 channel surround receiver. Weather you run it as a 7 channel theatre or as a more classic 2 speaker configuration, you will want to run the 901 cabs from the Front L and Front R speaker outputs, unless for some reason you want to specifically use them for any of the surround channels in which case it will not harm anything if you use them for surrounds - it's just that if you're simply wanting to use them as your principal speakers, you want Front L and Front R.
So connect them as I explained, power the receiver up, put on your favorite CD and enjoy!
