Question about Yamaha RX-V492 Receiver

1 Answer

Am noise I have a Yamaha tuner about 5yrs. old. I also have a Yamaha amp and cd player, all correctly connected. Have always had weak am and great fm reception because of where the tuner is located. Recently have experienced severe noise in am reception when anything on the same circuit is turned on (lights, dryer, washer) sound improves and noise reduced if i touch any of the three cases. what happened?

Re: am noise

In the AM frequency range, it is very hard to stop any type of interference because of the low bandwidth and not a lot can be done to suppress it, and where this band is in the frequency spectrum. There should be an AM loop on the back of your receiver, and if there is not, maybe that is why the AM reception is so poor. You can also be a better AM antenna from an electronics store to hook up to your receiver. Like I said, not a lot that can be done for interference my friend.

All input sources eg. DVD, cab/sat, cd, tuner etc have audio out of the amp ... but not the tv. Can someone help me with this one?

Have you checked to make sure the TV connection is from the correct TV output? The TV is not on mute? Recheck all connections. The amp obviously works ok.

FM Tuner not receiving - Yamaha R7 receiver

Take the cover off and look at the cable that connects the tuner to the main board. Make sure it is connected straight and tight. Make sure all screws in the back are tight, just in case it is a grounding issue. Iff all checks out and you still have issues, replace your tuner.

How do you connect sony str-de 698 fm receiver to television, cable box and cd player

Connect it's two audio plugs, likely to be coloured red and white, to corresponding sockets on any device that has them and select that input on the device. You should then hear your tuner.
Depending on FM signal strength where you live you may need an aerial, some is always better than none.

Amplifier - TA-AX380; CD Player - CDP-C40; AM/FM Tuner - ST-JX380; FM Stereo/FM-AM Receiver - STR-AV570X, and Stereo Cassette Deck - TC-W380.....all Sony. Very old system, do not have the manuals, they...

Since you have 2 receivers, you can either use the Sony STR-AV570X or the TA-AX380. You will need 3 Stereo RCA Cables to connect your CD Player, Tuner, and Tape Player. The speakers connect to the receiver you choose using the speaker input terminals.

My tuner will not work! I've had this unit for 4 years & it's always worked perfectly. Then yesterday, the tuner stopped working. "Tuning" flashes on-screen intermittently & no...

1. Verify the source of the signal - Look for any antennas that may have been hooked up, and verify connection has not been moved or removed.
2. Test with a different output by plugging in some headphones, and recheck the volume through the headphones.
3. Check that the A/B switch for the speakers has not been moved, and that they are switched to the correct speakers.
4. Try AM and FM for any signals both with speakers and then headphones.

Good luck!

Yes, that will be fine just make sure its the same AC power as the new Yamaha is using.

Before connecting any AC mains always turn off your Amp, and don't turn back on again until all the signal cables for the new equipment are connected.

When checking if it all works, always start with low volume to check everything is correct.

Hope this helps
Thanks for using FixYa

Yamaha RX-V757: Tuner not working

Is it set for XM / Sirius? If so, you need their special antennae unit; or are you talking AM & FM?

FM tuner does not play

Hard to say without knowing more, but many tuners have a squelch function that "mutes" the output unless the signal level reaches a certain threshold. You might want to look at the control panel and search for such a switch and de-activate it.
You didnt say if this was connected to an external pre-amp or a power amp. If so, the issue could be simply one of the correct cabling and selector switch setting

There's possibly some leakage internally.

Do you have a normal (Playback only) CD player on the MD/CD-R input? It's supposed to support a RECORDING device as you can see by the OUT (REC) connections. A recorder would have shielded cables there and maybe the circuitry is such that ungrounded/unshielded output to the recorder allows a leak of the FM, which is developed inside the receiver.

Since you know that FM is leaking why don't you just selct some other idle source before selecting MD/CD-R? Have you also heard, say, the DVD, if it is playing when you select MD/CD-R?

Or skip the analog route entirelzy and run digital cables from your CD player to one of the Digital Inputs, if you have a spare one. They're all functionally the same. I guarantee the FM won't get in that way.
