Sony BRAVIA Theatre Bar 8 / Bar 9. Known no-signal idle timeout, not TV power-off interlock or protection shutdown.
Connection scope: Device controls / power only. 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
Does the event match Auto Standby On after about twenty minutes with no input or operation?
Shutdown during active playback, overheating or TV power commands is different.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is no software installation or live session running?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is no software installation or live session running?
Do not interrupt an update to test a power preference.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do you want the bar to remain on until deliberately put in standby?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Do you want the bar to remain on until deliberately put in standby?
Disabling idle power saving increases time powered on; retain the original state.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Set Settings > System Settings > Auto Standby to Off
- If No → Stop at the unconfirmed condition

step-3
Set Settings > System Settings > Auto Standby to Off
Leave Network/Bluetooth Standby, TV power links and Auto Update unchanged.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Does the same ordinary idle interval now leave the bar on?

step-4
Does the same ordinary idle interval now leave the bar on?
No forced mains cycle is required; choose Unknown if that later observation is unavailable.
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.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
