SOURCE: RX-V661 Receiver

your receiver has zone 2 output which is operated independently of the main reciever. so you can have a dvd playing inthe main reciever and the tuner playing over the intercom. read about it in your manual page 89. in will hook up to 2 RCA jacks in the back Zone 2 out.

SOURCE: Input selector on my Yamaha RX-V596 stuck

Hi Dush

Sounds like the processor has locked up in the unit. Try powering it right down from the wall socket for a day to reset, and then retry operation. If that does not work, leave it disconnected for about 10 days to erase backup memory completely and then try again. Good luck. Don't forget to give me a "FixYa" rating if this works. If it doesn't, get back to me in here and we can talk more about it.

regards
Graeme

SOURCE: right speaker goes off when using Rec out on the Phono input

The switch is contaminated. Pick up some electronic switch cleaner and spray into the switch. Move the switch back and forth a number of times and that should clear up the problem. Make sure that you get the cleaner that has a lubricant included.

SOURCE: Subwoofer

Without being able to access the receiver in person, the best advice I can give you is to sit down with your user manual and follow the instructions. You'll find, starting on page 85, the necessary settings for hooking up a subwoofer to the receiver. If you don't have the manual, you can obtain a pdf file at Yamaha.com: http://www.yamaha.com/yamahavgn/Documents/YEC/AV_Receivers/Manual/RX-V663_U-1.pdf

SOURCE: I took my RX V3000

Hello
DSP boards are not repairable. We have to replace it as card basis itself. Used cards may always have some fault with them. Original replacement is always the best for this section, because this is the heart section of your Yamaha 6.1. $600 is a nominal rate I thinks. The DSP boards cost more than any other section boards. Make an agrement with them to get it seviced for this amount. OK.

RX-770 Input selector noisy - can this be fixed economically?


There are a number of ways to fix this, a quick fix is to rotate all the controls through their full range(with power on) this will give a quick clean to the contacts. The best thing would be to get the unit serviced at a Yamaha Audio dealers. They may have to replace the failed control switches, This will be cheaper than replacing the complete unit. You could do this yourself, if you feel confident to replace the switches, they should be available by part number on the internet.

Sometimes only one channel plays when playing CDs or DVDs. Jiggling the input knob will at times cause both channels to operate. This unit is a Yamaha RX-770 that I bought new. Thanks!


It sounds like you know what the problem is. Get it fixed.

Or try this temporary fix.

Or turn it off and manually operate the selector and all controls a thousand times to wipe the apparent oxides from their contacts.

3090 input selector cuts in and out


My A3090 was purchased in 1996 and began to having problems with the input selector around 2006. The first symptom was difficulty finding the proper position for a input selected via the remote and bouncing back and forth many times before stopping-- sometimes in the correct position, other times not. Sometimes the selector would stop in between inputs and that would result in intermittent loss of sound, picture, flickering, etc. Once incorrectly positioned between inputs, even manually turning the knob will not fix the problem-- you must use the remote and select an input at one extreme or the other to reset the indexing.
Recently the problem worsened such that I was motivated to remove the cover and have a look. The selector and motor are soldered components on a small circuit board that appears to be dedicated to just that function. No rotary contacts are visible and the mechanical portion does not look like it can be disassembled without first removing it from the circuit board. The assembly is connected via a wire bundle and ribbon cable to two other circuit boards. I suspect the actual signal switching isn't even done inside the selector component-- it just reports the selector position via the ribbon cable to the main processing board. And it wouldn't surprise me if there aren't any contacts inside the selector that can be cleaned.
Seeing the ribbon cables immediately raised a warning flag because decades ago I saw similar cable connections cause many problems in personal computers. Back then they were very prone to corrosion and connection issues at each end. So I removed and reinserted the ribbon cable on both ends in hopes of improving the connections and that seems to have fixed the problems I was seeing. (Please note: This was done with the receiver power cord unplugged and *very* careful avoidance of any other components inside the receiver-- like the bank of capacitors adjacent to the input selector. I'm not a technician and don't know if any of them still held a charge. This is just an account of what I did and the results I saw, it's not a recommendation.)

RX-V1600 when i turn on no sound or channels display on


If you are sure that the speaker wiring is correct and connections are good, then:
  • Check the input and output connections are correct for each source.
  • Check that the input mode is not set to DTS or Analog - rotate the input selector to the source and the press the input mode, set it to Auto.
  • Also check that the front speakers to be used are selected A or B (or A+B).
  • If there is an optimiser microphone supplied with this receiver, ensure that it is not still plugged in.
Hope one of these solutions work for you.

I have a Yamaha Natural Sound Stereo Receiver RX-750 (purchased maybe around 1992-1993?). The input selector switch doesn't seem to be working properly. No matter which input I select, the sound is fuzzy...


Hi cfipp
You could fix this problem with a quick squirt of CRC 2-26 into the function selector switch connected to the knob you are wriggling. This will sort out the problem. If you need further advice, feel free to ask me. I will help you.

never use the phono input this is for turntables,connect this amp to your speaker switch/selector then to speakers.

Noisy channel of receiver


Generally, crackling noises come from anyplace there is a mechancial connection for the sound signal. The volume control, main/remote speaker switch and possibly the headphone jack. That is where the contacts must be cleaned, but it requires dissassembly. Try operating the main/remote speaker switches, and plug/unplug a headphone several times. I am assuming there is still audio behind that crackling. Are you using both main and remote speakers simultaneously?
