Hello,
To open your ps3, you need to first shut it down and disconnect all the cables connected to it, wait for about an hour for the high voltage in it to dissipate. The you get a screwdriver that matches the screws on it.
Pull
the warranty sticker off of the bottom of the PS3. This will void your
warranty, so make sure that the problem you are addressing is not
covered by your warranty. Note that taking your PS3 to be repaired by
someone other than Sony will still void your warranty. You are not
losing anything by taking apart your PS3 yourself. Under the sticker
will be a small piece of rubber that hides a single screw. Remove the
rubber piece and unscrew the screw.
Slide
the faceplate off of the PlayStation 3. After the faceplate is removed,
you can now separate the two halves of the plastic covering. Remove and
set aside the top piece of the plastic case to expose the internal
components of the PS3. On the underside of the top plastic covering,
there will be a memory card slot at the bottom-right corner.
Locate
and remove the Bluetooth circuit board. Remove the four screws to lift
the Bluetooth board free. This is located at the bottom-left corner of
the main body of the PS3 if you have the system flat on its side
instead of standing up straight. This will look like a green rectangle
with a tan metal covering.
Locate
the small circuit board that controls the power and eject functions of
the PlayStation 3. Remove the four Phillips-head screws in order to
separate this piece from the body of the system. This is located at the
bottom-right corner of the PS3, directly in front of the disc box.
Locate
and remove the Blu-Ray/PS3 player. This is the large tan metal box that
is located in the top right corner of the PS3. Unscrew the player and
flip it upside down to expose the circuit board that controls it. If
you want to remove the circuit board, there are five small screws that
hold it in place.
Remove
the power supply from the inside of the gaming system. This is located
at the top-left corner inside the PS3. To remove this component, there
will be two telephone-like plugs that have to be unplugged, one at the
top and one at the bottom of the power supply. Additionally, there will
be 13 screws that hold the power supply in place. The back and front
plastic coverings of the PS3's shell will now easily slide free.
Remove
the final internal component, which is the PS3's motherboard. In order
to do this, remove the metal covering the rests on top of the
motherboard. There will be 11 screws that border the metal covering as
well as four screws in the very center, two from each of the
rectangular center pieces. Once the screws are removed, the metal
covering will lift off and the motherboard will be able to be removed.
But before you get to all these parts you must have gotten your DVD movies out.
Take care
