Zeki TBQG884B Motherboard Replacement

Remove the two screws from the end of the device where the ports are located.

Rest the tablet on the glass face.

Insert the tip of a plastic opening tool into the small gap, between the grey and white plastic. Pry it open, (you should hear the clips opening up).

Gently work your way around the perimeter of the tablet's edge.

Separate the back and face plates.

Remove any tape on the speaker, and detach the speaker from the back plate.

Remove the Wi-Fi antenna element, which is highlighted by red in the picture, from the front plate.

Use the same screw driver as the previous step, and unscrew three screws. (Circled in the figure.)

Open the ZIF connector. It will look like a black locker, covering a wire ribbon. Then, remove the wire ribbon that connects the motherboard, and the screen.

Remove the other wire ribbon on the opposite side of the motherboard.

Now, remove the motherboard and replace it with a new one.
