Question about Yamaha RX-V620 Receiver

Open Question

Volume control not working

The front panel volume control is not increasing or decreaing the volume - it's OK with the RCU. The volume control is sending out it's pulses OK, so the problem is further downstream. I can't find a schematic for this model, so any suggestions would be welcome.

The volume knob issue alone sounds like it's hardware-related and therefore not easily fixed. Also, since the remote appears to be working (the LED's are lighting up), but the unit is not controlled anymore, the IR sensor is probably faulty as well. I would seriously consider sending this AV receiver in for repair. If it's still within warranty, you shouldn't need to pay anything for the repair.

Manual for your receiver:

It's not much but I hope this helps.

Volume goes up and down by itself

Hi wally,

It is sad your having a problem with volume automatically increases

and decreases without any manual input.

These could be caused either by a component on the circuits

( front panel), a faulty regulator or microprocessor.

Components :

can be such as tact switches , diodes

PCB foil tracks, connectors. These means it may needs servicing.

Start with the basics, take out batteries from the remote, and see

if it affects the receiver volume or the one causing the problem.

If the symptoms still persist, One may have to open it up.

and check on it.Have a tech to guide you if you feel you can DIY.

One of the ways to tackle these problem is to take out the

tact switches , or have it disconnected . And use the remote

volume control to adjust the main volume.

If these works for a day or two, find or order replacements

for the said bad components.

There might be other ways but that is what Tech are for.

Let us know what you find , or needs further assistance.

My Amplifier is in good working condition, except for the volume control has gone weird Using the remote, you can increase volume, but not decrease volume. On the unit, rotating the volume control...

Cleaning the contacts may help. The volume knob should pull off. Once its off use a non-flammable contact cleaning spray to clean the contacts behind the knob.

Electronics and automotive stores should have this.

I have the Subwoofer plugged into the output and have it turned ON but it's still not working!

It only drives a self-powerd sub.

The manual...

Page 17:

Setting the Subwoofer Information

Register whether you have connected a subwoofer or not.

Before you start, remember....

• There is a time limit in doing the following steps. If the setting is canceled before you finish, start from step 1 again.

On the front panel ONLY:

1. Press SETTING repeatedly until "SUBWOOFER" appears on the display.

The display changes to show the current setting.

2. Press CONTROL UP / DOWN to select "YES" or "NO."

• Each time you press the button, the display alternates between "YES" and "NO."

YES: Select this when a subwoofer is connected.

NO: Select this when no subwoofer is used.


You cannot use SUBWOOFER OUT ON/OFF on the front panel (see page 14) and adjust the subwoofer output level (see below) when "SUBWOOFER" is set to "NO."

Then continue with setting its relative level and other things.

The receiver works ok until the vol is reduced and the right front channel drops out. Increasing the vol usually picks up the dead speaker but it drops out again when the vol is reduced. I've tried...

Make sure the audio level on the left and right channels are balanced. Check the menu for audio levels to adjust and make sure they are not maladjusted. If all levels are adjusted properly then the volume control or volume control circuity may be at fault.

My yamaha receiver shuts down when I turn it up.

If you have bare wire going into the receiver's output terminals, make sure a strand or two of wire is not touching the other terminal. That can short out the outputs, especially when you turn up the volume, which increases the voltage present at those terminals. That would cause the receiver to shut down as a saftey precaution.
