Follow these checks in Audio Fix →When this guide applies
The bar is confirmed off, not playing or updating.
Connection scope: Bluetooth. Symptom: Power-on or automatic standby isn’t working.
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 the bar confirmed off and not updating?
Do not toggle a unit whose current state cannot be established.
Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.
- If Yes / this check is completed → Is the original power connection dry and undamaged?
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-1
Is the original power connection dry and undamaged?
Stop for damage, liquid or abnormal heat; this does not inspect internal power circuitry.
Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.
- If Yes / this check is completed → Briefly press Power once
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-2
Briefly press Power once
Use a short press to turn it on. Do not hold more than three seconds, which changes the network/power state.
Look for: Perform only the stated check, then confirm whether it could be completed.
- If Yes / this check is completed → Does the normal on-state appear?
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-3
Does the normal on-state appear?
Observe the bar indication before returning to Bluetooth playback. If state is unavailable, use unknown.
