contact between the tablet screen and the controller body’s Type-C connection cable.

Follow the instructions below to reinstall and improve the USB connection.

2. Steps to Reinstall the Type-C Connection Cable

Step 1:

Remove the two screws securing the bracket that connects the screen to the controller.

After removing the screws, gently pull out the bracket to separate the screen from the

controller.

Clean the dust and debris from both the Type-C port and the groove area on the bracket.

then tighten the two screws from Step 1 securely.

If the same problem still occurs after cleaning the USB port, please replace the new screen

or exchange the screen for the customer. If the issue still cannot be solved, you can only

replace the remote control for the customer.
