Follow these checks in Audio Fix →When this guide applies
An existing known appropriate stored timing correction is bypassed by the current input Option Lipsync Off.
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
Is a known previously appropriate Lipsync correction already stored for this same source and display path?
An unknown, obsolete or different-input timing value is not adopted.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is this current input Option Lipsync explicitly Off?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is this current input Option Lipsync explicitly Off?
An already enabled or unknown state needs a different check.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May the stored correction be re-enabled with the previous Off state retained for reversal?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
May the stored correction be re-enabled with the previous Off state retained for reversal?
Compare the same scene without changing television processing.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Set Option > Lipsync > Lipsync to On for this current input
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Set Option > Lipsync > Lipsync to On for this current input
Leave the stored Setup timing value and every other input unchanged.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Does that same scene recover the intended timing preference?
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-4
Does that same scene recover the intended timing preference?
Restore Off if worse; no measured lip-sync result is claimed.
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.
