When this guide applies

Exact Denon DRA-900H. Normal standby policy only, not a protection fault, mains cycling or first network setup. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

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 scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

Confirm the exact setup

The unit wakes normally from its own power button, the home network already works while awake, no update is in progress, and its owner accepts inspecting standby energy/wake policy.

Look for: Choose only a detail you can confirm.
