Could a failing FrSky ISRM-N Internal RF Upgrade Module cause the FRSKY TARANIS Q X7 to have symptom: Not Found?

The 'Not Found' error is a result of a communication timeout on the internal serial bus between the radio's master microcontroller and the internal RF module. This occurs when the module fails to return a valid hardware ID or heartbeat signal during the power-on self-test (POST). If the firmware configuration for the internal RF type (XJT vs ISRM) is correct but the module remains unrecognized, the fault is located in the RF module's logic circuit or its voltage regulation stage, necessitated by a hardware replacement.
