Sony STR-AV770 AM/FM Tuning

Purchased a used Sony STR-AV770. Only for AM/FM radio listening and for to use with a Sony 5 disk CD changer.

CD connection works and sounds great!

When I try to tune in AM or FM stations the volume. I am having a very difficult time pulling in stations. So, first any suggestions on an good antenna to use for AM & FM stations.

My second issue is that I get a 'pulse' type feed back through the system in the tuner mode. Not with the CD player. But when I am on a frequency that is not receiving anything the read out is flat and then every 5-10 seconds a pulse of noise comes through and shows up on the monitor of the receiver, any suggestions would be great!

Thanks,

TV Roller

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.

Your system was an old carousel type CD changer. They do not make them anymore. The whole world is moving towards compact storage devices ( Hard disk / Flash drives ) and steering away from media like CD's , DVD's etc. Thanks to the internet, almost everything is available at your fingertips.
Today your system would be worth less than half of what you paid. In fact for half the amount you could pick up something similar with only one CD tray, but with a USB port for playing MP3 / Video files.

I have seen the higher power cb's fry the fm front end sectioon of the tuner section....did you try to put it on an aux input?....the click you hear is the amp protection relay and it sounds like it is working ok....if it were the output side of the power amp, then the relay wouldn't click after power up...it is probably the front end...this is the entire fm tuning section usually contained inside a metal box near where the antenna comes in

How do I preset the tuner for radio stations. I've never had a problem doing this with any other stereo. But what I think should work isn't!


Not very specific. Do you have the manual?

The following is from a VSX-03TXH manual. It ain't pretty but it may help.

I'm posting it in multiple parts due to space contraints.

Chapter 6:

Using the tuner

Listening to the radio

The following steps show you how to tune in to FM and

AM radio broadcasts using the automatic (search) and

manual (step) tuning functions. If you already know the

frequency of the station you want, see Tuning directly to a

station below. Once you are tuned to a station you can

memorize the frequency for recall later-see Saving

station presets below for more on how to do this.

1 Press the FM/AM button to select the tuner.

2 Use the FM/AM button to change the band (FM or

AM), if necessary.

Each press switches the band between FM and AM.

3 Tune to a station.

There are three ways to do this:

Automatic tuning

To search for stations in the currently selected band,

press and hold TUNE ?©/?? for about a second. The

receiver will start searching for the next station,

stopping when it has found one. Repeat to search for

other stations.

Manual tuning

To change the frequency one step at a time, press

TUNE ?©/??.

High speed tuning

Press and hold TUNE ?©/?? for high speed tuning.

Release the button at the frequency you want.

Improving FM stereo sound

If the TUNED or STEREO indicators don't light when

tuning to an FM station because the signal is weak, press

the MPX button to switch the receiver into mono

reception mode. This should improve the sound quality

and allow you to enjoy the broadcast.

Using Neural THX

This feature uses Neural Surround™, THX® technology to

achieve optimal surround sound from FM radio.

• While listening to FM radio, press AUTO/DIRECT for
Neural THX listening.

I HAVE A SONY RECIEVER STR-DH700, I get no sound


make sure the FM antenna is connected and in a good place then check to see if the A-B speaker selector is selected properly.check to see that the sound field is set properly, My 800 allows for several different options and if your speaker wires are reversed or not in the correct position front left at front left etc it will not send the signal to those speakers. try using the TEST TONE feature if you have one it will send a signal to each speaker in sequence (LF< C< RF<in order) it will go all the way around to see if they are connected properly, that way you can tell if they are connected at all or in the wrong spot on the back interface. I dont know if that is what you meant by AUTO CAL, but that is a seperate feature when you use the connected mic to determine range, height and distance to the position in the room you are most likely to be seated for optimal sound.

See add details


Since the receiver eventually works, the delay circuit is failing. This is a circuit that allows the power supply to settle down before kicking in the output relay. This prevents the "pop" that was sometimes heard on older units. This should be a simple and inexpensive repair probably requiring the replacement of a couple of small capacitors in that delay/protection circuit.

Don't receive hardly any FM stations


Well I would consult your manual.  Home receivers usually dont have the same amplification factors that a mobile unit does as far as sensitivity.  But for best results make sure that you are using the supplied antenna, and put aluminum foil over it.  This will help amplify the signal.  Also consult the manual as to weather there is a setting for DX or Local.  If there is, make sure that it is not set to local.

Direct tuning


Unfortunately, according to the manual you can not directly tune a station.

Dowload the manual here:

and go to page 50.

Manually tuning the reciever


you should be able to tune in manually.
press tune
press fm or am
press d. tuning
enter the frequency of the station 4 or 5 digits ie 9370 or 10450

another thing to look into would be getting a yagi fm antenna, they are directional and although you may have to rotate it for best results, they work great.
