You can learn how to fix a PS3 controller.Random button pushes are one of the most common problems with PS3 controllers.The easiest way to fix this problem is to disassemble your controller.Water damage and analogue sticks are some of the problems you may encounter.
Step 1: The controller has screws on it.
The controller is held together by five screws.There are two on one side and one on the other.
Step 2: The back should be removed.
You can use a flat head screwdriver to open the controller.From the bottom, tilt it towards the shoulder buttons.If you accidentally remove the R2 or L2 buttons from the back, be very careful.They can be difficult to put back on.
Step 3: The battery needs to be removed.
There is a grey square piece on the back of the board.The battery doesn't need to be disconnected.Pull it out of the holder and move it to the side.Pull the white plastic part that the wires are connected to if you decide to remove the battery.Don't pull the wires.
Step 4: The screw on the board needs to be removed.
The screw on the bottom of the board is next to the stick.
Step 5: The board is removed.
Pull the board up and tilt it away from the shoulder buttons.Again, be careful not to remove the R2 and L2 buttons.
Step 6: Pull the green ribbon back.
The controller front has a green ribbon at the top.Above the hole is where the left analogue stick goes.Lift the two plastic pins that are stuck up out of the controller with the help of a flat head screwdriver.Don't damage the ribbon.There is a strip of foam underneath the ribbon.
Step 7: The black foam strip should be removed.
The foam strip gets compressed and the ribbon isn't able to make contact with the board.The controller is malfunctioning.
Step 8: The black foam strip has tape on it.
To get the best results, cut a strip of thick double-sided tape the same length and width as the black foam strip.It should be placed under the foam strip.Use scissors to get rid of excess tape.If you don't have thick double-sided tape, you can cut about an inch-and-a-half of black electrical tape and roll it into a tube.
Step 9: The foam strip should be replaced.
You can put the foam strip back under the ribbon with the tape underneath.
Step 10: The ribbon needs to be replaced.
Put the two holes over the pins that are sticking up out of the controller with the ribbon.Make sure it's in place.
Step 11: Clean the ribbon.
Since the controller is open, it's a good idea to use a tissue or cotton swap to clean the ribbon.
Step 12: It's a good idea to clean the PCB.
If you look at the board, you will see a box that is a darker shade of green with some metal connections sticking out of it.The stick is above the analogue stick.This is where the ribbon is connected.To clean the mother board, use a tissue or cotton swap.

The analogue sticks are free to move through the holes if the board is placed back in it's place.
Step 14: Make sure the back of the board is in place.
Attach the same screw you took out of the board to the right analogue stick.
Step 15: The battery needs to be replaced.
There is a plastic holder on the back of the board.The battery should be in the holder.
Step 16: The controller needs to be replaced.
The controller needs to be replaced with a thin part that goes between the two shoulder buttons.Carefully tilt the back over the R2 and L2 buttons and push it back in place at the bottom of the controller.Don't accidentally remove the R2 and L2 buttons.
Step 17: There are screws on the controller.
The controller is held together by five screws.There are two on the sides and one in the middle.Your controller is working again.

Step 22: Remove the board.
Pull the board up and tilt it away from the buttons.Again, be careful not to remove the R2 and L2 buttons.
Step 23: The plastic stick should be on the metal rod.
There is a metal rod in the computer.The stick should be on the metal rod.
Step 24: It's a good idea to replace the board.
The analogue sticks are free to move through the holes if the board is placed back in it's place.
Step 25: Put the back of the board in place.
Attach the same screw you took out of the board to the right analogue stick.
Step 26: The battery should be replaced.
The battery is held in place by a plastic holder on the back of the board.The holder has a battery in it.
Step 27: The controller should be replaced.
The controller needs to be replaced with a thin part that goes between the two shoulder buttons.Carefully tilt the back over the R2 and L2 buttons and push it back into place at the bottom of the controller.Don't remove the R2 and L2 buttons.
Step 28: The controller has screws on it.

The controller needs to be replaced with a thin part that goes between the two shoulder buttons.Carefully tilt the back over the R2 and L2 buttons and push it back into place at the bottom of the controller.If you accidentally remove the R2 and L2 buttons, be careful.
Step 37: There are screws on the controller.
The controller is held together by five screws.There are two on the sides and one in the middle.
Step 38: The controller should be tested.
Launching a game that uses all the buttons on the controller is a good way to test it.Make sure the buttons are doing what they are supposed to.The controller is fixed if all the buttons work.There is a short in the board if there is any random button presses.The controller will need to be replaced.
