Question:

What does the error code AE4 or AC4 mean and how can I fix it?

Answer:

The error code AE4 or AC4 indicates a communication issue between the WiFi PCB (printed circuit board) and the main PCB. This could be caused by loose wire connectors, or a defect in either the main PCB or the WiFi PCB. To resolve this issue, check for loose wire connectors and ensure they are securely connected. If the problem persists, it might be necessary to replace the defective PCB (either the main one or the WiFi PCB).

Terms:

Error Code (AE4 or AC4): A unique identifier for a specific type of error or issue encountered within the system.

WIFI PCB: A printed circuit board responsible for handling wireless connectivity functions.

PCB main: The primary printed circuit board responsible for controlling most of the device's functions.

Communication Error: A problem occurring during data transmission between two components or devices, leading to impaired functionality.

Loose Wire Connectors: Poorly secured connections between electrical wires and their corresponding terminals on electronic components, potentially causing malfunctions.

Defective: Refers to a component or device that is not functioning properly due to an internal fault or damage.
