Display Replacement Instructions

Preparation - Make sure the device is switched off and not connected to power.

Step 1 - Using the provided suction cup, pull the screen firmly, but carefully upwards.

Step 2 - Open the FCC connector on the currently connected display - this can be gently pulled up, pulling upwards towards the nearest edge of the board.

Step 3 - Remove the ribbon cable from the FCC connector. You can then safely remove the faulty display.

Step 4 - Insert the ribbon cable into the FCC connector on the new board - This should sit firmly in place, and be aligned, not inserted at an angle.

Step 5 - Close the FCC connector - gently push the black connector down onto the ribbon cable so it grips.

Step 6 - Power up the device via the USB, and check the screen to make sure the display isn't damaged (We should see the OnlyCat logo on powering up).

Step 7 - Once confirmed that the screen is working - Place the screen assembly into the housing, ensuring the ribbon cable goes underneath the plastic bridge.

Step 8 - Place the glass screen over the top, applying firm pressure around the edge of the screen to ensure the adhesive takes.

If the screen is not functioning correctly, please inform us and we'll act accordingly. We'll do everything we can to ensure you're up and running ASAP. If you have any questions regarding the repair steps, please ask.
