LG S90TR / S95TR. The bar wakes and chooses a source with a known external-device power event; AUTO POWER On.
Connection scope: Optical digital audio · Bluetooth. Symptom: Switching between devices 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
Does the unwanted selection occur when a connected optical/Bluetooth device wakes the bar?
An already awake HDMI CEC takeover is outside this control.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is AUTO POWER explicitly On in the current remote settings?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is AUTO POWER explicitly On in the current remote settings?
Do not change an already Off or unknown state.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do you want future bar power/source selection to require manual operation?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Do you want future bar power/source selection to require manual operation?
Disabling this convenience also changes normal external-device automatic power behaviour.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Press Settings and choose AUTO POWER using Left/Right
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Press Settings and choose AUTO POWER using Left/Right
Do not select HDMI CEC, factory reset or source pairing.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Use Up/Down to set that actual AUTO POWER control to Off
- 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 Up/Down to set that actual AUTO POWER control to Off
Retain the original preference; stop if the available control differs.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → At the next normal external-device wake event, does the unwanted automatic selection stop?
- 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
At the next normal external-device wake event, does the unwanted automatic selection stop?
No forced power cycle is necessary; choose Unknown if that later observation is not available.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Checks completed — report the actual result

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.
