When this guide applies

Yamaha RX-A4A / RX-V6A. Both sides work; relative level differs only with All-Channel Stereo and its known unintended non-neutral balance.

Connection scope: Device controls / power only. Symptom: Sound plays from only one side.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

step-0

Do both sides already work, with unwanted relative imbalance specifically in All-Channel Stereo?

A physically silent channel or another listening mode needs another check.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-1

Is that mode balance visibly non-neutral and confirmed unintended rather than installer compensation?

Retain the original value; do not alter unknown calibration preferences.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-2

May its balance preference be compared with levels comfortable and the same programme playing?

This changes relative left/right presentation rather than source channel content.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-3

Set Sound > All-Channel Stereo > Left / Right Balance to the displayed centre value 0

Do not change speaker Levels, Test Tone, room measurement or cables.

Look for: Perform only the stated operation, then confirm it was possible.

step-4

Is that same programme more evenly balanced in All-Channel Stereo?

A neutral setting is not proof of a measured speaker match.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

Possible result

Checks completed — report the actual result

Completion does not automatically mean the problem is solved. Report what actually happened; no physical test or measured repair is claimed.

steps completed

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Stop at the unconfirmed condition

    A required setup or response was not confirmed. Retain the actual observation and consult the exact source/partner manual or official support. Do not escalate to a reset, update installation, internal repair or unsafe wiring change.

    next support

    Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

      Possible result

      A required fact is unknown

      Confirm the actual model, connection, partner capability and state before continuing. Do not guess a menu, interrupt an installation or modify a live source by trial and error.

      insufficient data

      Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
