When this guide applies

A currently enabled30/60/90-minute Sleep Timer is unintended.

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

Is Sleep Timer currently known to be30,60 or90 minutes?

A default-Off manual entry does not prove the present setting. Unexpected shutdown with Off needs another investigation.

Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

step-4

Does the Sleep Timer setting now read Off?

This cancels that timer only; it does not diagnose temperature, protection or mains faults.
