1. Remove the left and right base

Remove the screws on each side of the base, and then lay the miner flat on the table so that the base is suspended. Hold the miner with one hand, use a rubber hammer or the another hand to hit it diagonally downward to make the plastic buckle of the base separate from the hole at the bottom of the miner.

2. Remove the main control board and LED screen

Remove the two screws that fix the plastic box at the bottom (which contains the main control board and LED screen) and gently remove it to the left. Pay attention to the cables connected to the host in this step.

Next, use an electric screwdriver to remove the four fixing screws, open the box upwards, and remove the four screws that fix the control board.

At this point, we can gently remove the control board, but we also need to pay attention to the cables connecting the screen. Finally, remove the LED screen upwards.
