Re: Speaker output

Yes, there are relay type switches associated with those outputs. Your RX-V1 is not dying.
Just plug a pin plug in and out of the dead channel to bump the switch. You will hear the speaker
come on. If it doesn't come on,do the plug jack in an out of the pre out again. It will come on.
You can use the test tone to check all channels and rebalance volume levels. You are making the
pre out connect to its power amp. It seems the problem got better when activating those switches. Most likely a cleaning issue. You can also jump the mains and center, and there is also
a modification to jump all channels. I bought my RX-V1 very cheap because of this and love it.
Of course outboard power amp would solve all, but getting this reciever to connect to it's own
power amp has been thrilling as far as bang for the buck. I do use the front effects also, and like
them. It may seem like a pain, but it is worth it to get those channels going.

Re: Speaker output

You can try all these temporary solutions but it is a real pain to lose you audio in the middle of a great movie.
I just fixed by RXV1 which was losing Center, Left and Right Surrounds. Mains never had a problem and Sub never had a problem.
Go to yamaha24x7(dot)com and buy 2 pcs of V806700 (black RCA connectors in PreAmp connctor bank); 4 pcs of V454850 (red/white RCA connectors in PreAmp connector bank).
Move the RXV1 to a sturdy work table (very very heavy!!). -Remove 4 screws from left chassis panel. Lift panel up and pull away from chassis to remove. -Remove right chassis panel the same way. -Remove top cover by unscrewing two top screws and two screws in top-rear corners. -Lift cover off and set aside. -Remove bottom panel by resting the RXV1 on right side and unscrew 12 screws holding in bottom plate. -While the chassis is tipped up, remove the black screw in near the middle support bar. This screw is found on the green circuit board near the support bar and is securing the audio board which you need to remove from the chassis. - Set the RXV1 back down such that all cards are up and visible. - There a a long string of black philip head screws between the PreAmp output connectors in the back (between the red and while RCAs). Remove all of them to be able to take out the audio card. - At this point, you will need to attach a ground strap from your wrist to the chassis to control static discharge and ruining your electronics. - The audio card is made up of two cards connected together. At the junction between the larger card connected to the main board, and the small card with all the connectors, gently separate the two cards by pulling the large card away from the small card. - remove the small wire connector at the top of the small card with all the connectors. -remove the large card from the main board by gently lifting from back to front (two inserting connectors in main board holding card). -I DID NOT remove the ribbon connector from the short connector card. I just place a board across the RXV1 chassis and did my unsoldering and soldering on this board. -I used a solder wick to remove the solder from lowest two (red/white) connectors, the next two black/black connectors, skip the connect with Black body (only one in this line), remove last two red/white connectors. - each connector is held in by 6 metal solder points plus 2 plastic holding tabs through the audio board. - Wick out all the solder from the 6 solder holes, and use a small flush cutting diagonal wire cutter and razor blade to cut off the plastic holders flush with the circuit board holes. - once loose, pull firmly to remove completely. Set this component aside and do not mix in with new components. - remove all of the lower RCA connectors except the 5th from the bottom. The solder pins on this is also different. - when reinserting the new RCAs, work from the one left up and down toward the outsides. This will make insertion easier. - Use a PC grade solder with resin and solder all the pins to the audio card. If pin is not visible, remove connector and straighten the pin to feed through the hole. - reinstall and reconnect the boards, - screw in card holding screw. -reassemble chassis.
Good luck.

Re: Speaker output

My unit does the same thing, I read online to install a RCA Patch cord from Main-In to Main Out and it worked.
I contacted Yamaha and they wanted to charge me to fix the issue and they will not fix it under warranty because I did not buy the unit from a authorized Yamaha dealer. Obviously a design flaw.

Yamaha rx 530 center channel cuts out

Thanks for all the suggestions guys.

I've tried using the balance for left and right speakers, and when the receiver is acting up with the right speaker having a low volume, I tried moving the balance all the way over to the right speaker. The right speaker volume will not increase in volume but the left speaker will decrease in volume.

Just to clarify, the center and the rear speakers are balanced. The issue only happens sometimes when I first power on the receiver I will have no center channel. If I leave everything alone for a few mins, the center channel will come on.

So it seems to me that something one the receiver is going. The question is, can anyone suggest a physical repair for the receiver for these symptoms?

Yamaha rx-v2500 receiver how to hook up speakers


Follow these steps to connect a powered sub woofer to your receiver: You typically have two options when connecting a powered sub woofer. Input (1) on the rear of the sub woofer would be used when connecting the sub woofer to the receiver using speaker wires. You would then connect the main speakers to the opposite end, or output or the sub woofer to the main speakers. Option (2) would be using RCA line level output jacks, input (2) on the rear panel of the sub woofer directly to the single sub woofer output on the back of an AV receiver. blank.gif

When I hook up the rear speakers to my in-wall speakers, I can't get any sound. I have speaker button 1 and 2 selected.

you need to clear that you connect wall speakers for font,center or rear (surround) speakers?
Seem you connect for Front speaker.
Rear (surround) speaker will have "rear" mark on the back of your reveiver.
In general you need to select both buttons 1 & 2 then check your speaker wires connect into "output1" or "output 2" hint: each output will have 1 for left and 1 for right speaker. Each Left or right speaker will have 2 connection 1 red color (+) and 1 white color (-). Try to match these colors code for your speakers connection.

Rear speakers are dead, never got them to work. Changed front to back and rears work so speakers and wireing are good. Is it possible that because I did not hook up a center speaker this is the problem?

if its a 5.1 channels it means 2 front speakers,2 rear speakers or either the center speaker or the subwoofer.try to hook up either center speaker or subwoofer.

Yamaha RX-V365 Receiver when I hook up my center channel it is not audible at all. The R and L speakers work fine when they were located in the FRONT A and FRONT B terminals, but when I moved everything to...

With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel.
Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.

If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver.
- Try connecting the center speaker to different output of receiver (this will test if speaker is OK).
- Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK).
- Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).

No sound out of right main when watching DVR/TV or VHS

When watching TV or VHS the sound should be stereo and therefor come out of the the 2 front speakers. I suspect you now have sound out of the left front and the center speaker which indicates you connected the center speaker to the right front speakerterminal and the right front to the center terminal.

Just check if all speakers are connected to the correspondent speakerterminal.

If this is correct and the problem persists, try to connect another speaker to the right front terminal to see of the terminal or speaker is not working properly. If another speaker does work on the same connection, your right speaker might be damaged which might not be heard when listening to 5.1 because of the surround sound.

A couple things to check on the no bass problem:
1) Make sure your center speaker is set for normal, not large.
2) Make sure your speakers wires are in phase (+ conn. to + and - conn. to -).
