Why am I not getting sound anymore?


Amplifier issue. See if you are getting audio signal at audio outputs used for recording. If not, then it is NOT the audio amp and the proceeding circuits are responsible.

U might also want to check out your power supply voltages to make sure that the other components are being properly fed.

I can't get am or fm reception. I can get output from 6-direct input but can't get radio output.


What happens during normal setup test tones?

The tuner requires an antenna and a station tuned for reception. But the audio will not be forthcoming from ANY source (*) if you have a switch out of position like, say, Tape Monitor.

* 6-direct bypasses Tape Monitor all other audio processes and sources. Disable IT.

It's in the manual - page 10.

Sound not coming. what would be happen?


Have you selected the speaker option correctly. There are two button on the front panel labeled Speaker A & B. Select any one or both and see if you get sound. Make sure there are no objects pushed into the headphone socket.Test while playing a tuned radio station , make sure the tuned light and stereo indicator is on,that way we can rule out wrong connections at the back. Last - you wont hear sound if the Tape Monitor switch is on.

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.

Auto muting on when on am/fm and no sounds come out. everything else is fine.


That's normal.

The Auto Muting mode mutes the audio output of the tuner if the station is not sufficciently strong to be accurately tuned. Otherwise you would hear all that interstation hash noise.

Press the FM Mode button to change it to Mono if you want to manually tune a hard-to-reach station. It will be in Mono.

Page 26:

AUTO MUTING
Normally select this.
When a program is broadcast in stereo, you will hear stereo sound; when in monaural, you will hear monaural sound.
This mode is also useful to suppress static noise between stations. The AUTO MUTING indicator lights up on the display.

RE: FISHER RS-909 I can find radio stations by switching from "CH" to "Freq" and then pressing "+" or "-" ... but how do I then pre-set the stations? Very frustrating! Thank you for any...


OK, I'm writing info here as I couldn't get response in chat session.
Once FM station got tuned, press memory/ store button, display will flash, press preset number like 1 or 2 or other to store that tuned frequency in that particular preset.
Let me know for further question.
Thanks.

Distorted sound in channel


PLEASE :) wear saftey goggles, no jewelry or watches while troubleshooting a live amp. Tube amps have up to 600V dc on some points so rubber gloves will improve the saftey margin. My primary suggestion is to take it to a pro. Please be safe if you are inexperienced. I can't be liable for my fixya suggestions.

I think you meant "changed" Left speaker with Right Speaker and visa versa. Some receivers have speaker A and B selections from a switch on the front, which is why I ask. I think you tried each speaker on the bad channel to find if the speaker was blown. If the speakers are OK make sure that the speaker wiring is good too. Sometimes they can be compromised so use two short lengths of new wire for trouble shooting. Try the other functions like tape, cd, phono, aux, dvd, ect. and if there is no problem with them then it is your tuning system. Check your antenna first. Make sure you are tuned to the station with max power received. Sometimes you can lose Stereo with analog tuners or be tuned to a harmonic frequency close to the target frequency. Check all of the fuses. Sometimes slo-blo fuses can blow incompletely resulting in a high resistance that causes a voltage drop. If the problem is still there you have trouble in the RF receiving/pre-amplification circuit or blown components in the output transformer/tube/transistor circuit. This is verified by having the same problem with the other functions above. In either case, you will need to take the unit to a repair service or get a service manual and test your voltage points to determine which components are bad. Without a service manual, I would start with the Left output transistor. Check the AC and DC voltages with respect to ground (chassis or negative output/input) on the good channel at all nodes and compare them to the same ones on the bad channel. Again, start with the output circuit for the amplifier. There will be one or more transistors per channel. They will be screwed to a heat sink. Also look for brown, cracked or melted components. Keep in mind that replacing these does not necessarily fix your problem as there is usually a failure elsewhere which caused them to go bad. Work your way back to the actual input signal and you will have hopefully found the problem. Good luck, be careful, and seek some local advice from your friends or repair technician. Happy Shooting!

I have tuned in my video to my tv but I cannot get the tv station


I had a similar problem. After a nearby lightning strike I lost video to the TV. When the SA-HE100 source switch was set to DVD or TV I lost the TV picture. In my system configuration I send composite video (yellow jacks) to the SA-HE100 from the DVD player, VCR and satellite receiver. From the "TV Monitor Out" jack (yellow jack) the video goes to an RF modulator then is sent to the TV as RF channel 3. At first it seemed the modulator was defective but plugging in another identical modulator damaged the second unit also. This made me look at the amp as the culprit. Curiously, the amp would pass through VCR video without a problem but I didn't know it because of the damaged RF modulator. Whenever the amp source switch was set to DVD or TV the amp would put -4.75V DC on the "TV Monitor Out" jack thereby damaging the connected RF modulator. The repair is relatively simple. The only special skill required is you will need to be able to desolder a 14 pin DIP IC. The damaged component on my amp was IC364 mounted on the board that holds the yellow video jacks. The IC is a JRC 2279D, a 3 input/2 output video switch available from Digikey p/n NJM2279D-ND, $1.50 each.

No sounds


Test one speakers at other amp to ensure its working. Amp is going into probable protection mode. Disconnected all speaker and av wires (only power) turn up volume and see if it stays on. If not sounboard or volume function faulty. If on, connect one speaker L or R. Go to tuner mode to tuned radio station an listen for sounds. If sound connect speakers and av cables one by one and test each one on its own until amp switches off, or no volume. Investigate from there were prolem is.
