When this guide applies

Known HDMI input; audio arrives before the picture.

Connection scope: HDMI / ARC / eARC audio. Symptom: Sound and picture are out of sync.

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

Does the audio arrive before the corresponding picture?

Adding delay cannot advance sound that is already late.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-1

Is a supported normal listening mode active with the delay control available?

Do not blindly leave Direct/Pure Direct/Pure Audio or change a listening mode just to make a hidden control appear.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-2

May this input timing value be changed temporarily?

Record the previous value for restoration. No TV Auto Lip Sync capability is assumed.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-3

Open Quick Menu > HDMI > A/V Sync

Use this model-specific control name rather than another brand menu.

Look for: Perform only the stated operation, then confirm whether it could be completed.

step-4

Add only a small delay and compare the same scene

Stay within the values offered by the receiver; restore the old value if worse.

Look for: Perform only the stated operation, then confirm whether it could be completed.

step-5

Is synchronisation actually closer on that same input?

Changing a number is not itself proof of an improvement.

Possible result

Checks completed — report what happened

Completion is not an automatic solved result. Report solved, partly helped, did not help or could not follow based on your actual observation. No Audio Review physical test is claimed.

steps completed

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

    Possible result

    Keep these observations for official support

    A required prerequisite or response was not confirmed. Stop this sequence and use the exact model and partner documentation. Do not escalate to a factory reset, firmware 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 exact model, connection, partner capability and current control state before continuing. Do not guess settings or operate an updating product.

      insufficient data

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