When this guide applies

Compatible IP control works while awake, but Connected Standby is disabled.

Connection scope: Wi-Fi / Ethernet network audio. Symptom: The control app cannot find my device.

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 compatible IP controller already operate this unit while awake on the same network?

Unknown network setup or unsupported software is outside this flow.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-1

Is Connected Standby currently disabled?

Do not change an already enabled or unknown state.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-2

Do you accept increased retained standby operation to permit network wake?

This changes the low-consumption standby choice; retain the old setting.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-3

Enable Connected Standby in Preferences

Leave IP addresses, ports, CEC and RS-232 settings unchanged.

Look for: Perform only the stated operation and confirm whether it was possible.

step-4

May normal standby be tested with listening idle and no update active?

This interrupts the awake session.

Look for: Confirm the stated setup or observation. Unknown stops safely.

step-6

Send its ordinary power-on command from the previously verified controller

Use the same known local network route.

Look for: Perform only the stated operation and confirm whether it was possible.

step-7

Does the intended receiver wake from that command?

A saved setting does not prove controller reachability.

Look for: Confirm the stated setup or observation. Unknown stops safely.

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Stop and retain the actual observations

    A required fact or response was not confirmed. Consult the exact product/partner documentation 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, source, partner capability and current state before continuing. Do not guess a menu or interrupt a live session/update.

      insufficient data

      Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
