Follow these checks in Audio Fix →When this guide applies
A known working TV path has sound before picture; manual delay is available.
Connection scope: HDMI / ARC / eARC audio · Optical digital 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 audio arrive before the matching picture movement?
Extra delay can worsen audio already late.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is the current input identified, with the old displayed delay retained for reversal?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is the current input identified, with the old displayed delay retained for reversal?
Do not change another source or assume an undocumented range.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May a small reversible comparison use the same scene at the same comfortable level?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
May a small reversible comparison use the same scene at the same comfortable level?
Keep source and television processing unchanged.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Press DELAY once on the supplied remote
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Press DELAY once on the supplied remote
This enters the displayed delay adjustment, not a pairing or reset mode.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Use the actual + control for a small added delay within the displayed choices
- 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
Use the actual + control for a small added delay within the displayed choices
Stop if the response differs; the original value can be restored if worse.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Press DELAY again to leave the adjustment
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-5
Press DELAY again to leave the adjustment
Alternatively the manual describes automatic exit after ten seconds; do not press an unrelated control.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Is that same scene closer to synchronisation?
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-6
Is that same scene closer to synchronisation?
A changed display value is not a measured lip-sync result.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Checks completed — report the actual result
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is 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.
