When this guide applies

Exact Marantz MODEL M1. Known IR-emitting handset, unobstructed path, actual IR Control command visible; accept replacing only the chosen command assignment. Only normal external user controls; no reset, firmware installation, internal repair, mains alteration or earth lifting.

Connection scope: Device controls / power only. Symptom: An option or codec is missing.

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

Is the TV handset confirmed to transmit IR for the intended command, with no existing HDMI-CEC checkmark for that function, and do you accept replacing only this chosen learned assignment?

Look for: Choose only a detail you can confirm.
