Question about Technics SA-AX530 Receiver

1 Answer


My receiver has a broken main volume control knob and I use a remote for this. However sometimes when reducing or increasing volume there is a sudden burst of volume, ie it increases automatically to the maximum. Volume of the centre and surround channels plays at maximum even though you reduce it to minimum. I have since stopped connecting any speaker to these channels. What could be the cause?

I have a ge gtd 120 home theatre surround sound.for some reason, my volume is stuck on one level.. I haven't had a remote for it for a while, just used the knob to adjust the volume.someone plz help!

Unless the system has some kind of automatic volume control on it, that can only be adjusted by the remote. I think you might have a faulty volume/tone control circuit. These days many amps have a single IC that will control the volume. If that goes the volume can get stuck on one level. Since the control knob you are turning is simply sending a signal to that IC. So if the IC has died the signal is not being received.
If you want to repair it yourself just follow the wires back to the board from the volume control. You should see a large multi pin black box that if your lucky is marked on the board volume control.

I having trouble geting the tv sound to go through the dvd surround system speakers and do i also have to have a remote to equile the speaker volume on the surround system

If you have a volume knob on your surround receiver, you do not need a remote. I;m not sure what your problem is, but if you want the TV to be broadcast through the surround sound system, you need to connect audio out from the TV to audio in on the receiver on a separate channel than what the DVD is hooked up to. Then pick that source on the receiver that corresponds to the TV out. I hope that helps.

Volume Knob does not adjust volume, but remote does.

Check your owners manual for "factory reset" this will reset the main micro-processor. Otherwise the encoder (volume pot) needs cleaning, soldering or replacement. It could also be a cracked circuit board (if it has recently been hit)

Yamaha RX-V800 volume knob on receiver not working.

It sounds like the volume control pod has gone bad and needs replaced (The knob shaft connects to the pod main body and the inside of the volume pod is what controls the rate of volume,If the inside becomes worn ,broken or dirty the volume will become erratic) Replace volume pod ! ..You may try cleaning by taking off the volume knob and getting a can of pressure air and blowing the dust out!
Please rate response!!

Broken volume knob

I located the remote control for the unit and it works fine. As the unit is not the primary amplifier for the home stereo system, I use the remote to control the volume. Thank you for your quick responce, and I will keep you in mind for any future needs.

Volume control on unit

Kent, Unfortunately, it sounds as if the encoder is broken. The encoder is a digital input which takes the place of a traditional volume control, and is what holds the volume knob in place and spins. Since it works fine with the remote, that means everything else is ok, but you will have to replace, or have a tech replace, the encoder itself.
