how to fix a ps3 by reflowing the motherboard

by:Mingfa Tech     2020-01-15
When the Playstation 3 is interrupted, a yellow light is usually seen, followed by a flashing red light.
This is what is commonly called the yellow light of death.
For many, this means the time it takes to replace or send it to fix it.
Despite what its name is, it\'s not necessarily the death of your console.
A common cause of PS3 failure is a crack in the ball grid array solder joint.
Important: If your console is still under warranty, it will take only Sony repair.
Using this method will absolutely cancel your warranty.
This Instructure shows how to fix the problem by putting the motherboard in any regular kitchen oven.
This repair can take two hours, and it is important to have one repair in order to avoid missing parts. -
Broken Playstation 3 ~3.
Cross screwdriver 0X40
1 Cross screwdriver
T8 Torx screwdriver (
You can also use flat heads of the same size)-
A tube of hot paste (
Can be found online or in many e-stores)-Cookie Sheet-Kitchen Oven1.
At the bottom of the console, find a plastic cover that says it can hold the hard drive. 2.
Remove the lid.
It should ring right away. 3.
This will show a blue screw.
Remove this screw with a smaller cross screwdriver. 4.
There is a metal label on the hard drive.
Pull this until the hard drive comes out. 5.
Next to the hard drive slot, find a sticker that says it will cancel your warranty if removed. 6.
Warning: removing this sticker does cancel your warranty on Playstation 3.
If your warranty is still valid, stop immediately, replace the hard drive and contact Sony to fix your console for free. 7.
If your warranty has expired, then remove the sticker showing the rubber plug. 8.
Pull out the rubber plug. 9.
Behind the plug, there is a screw deep in the console.
Remove this screw using Torx or flat head screwdriver. 10.
The housing should simply slide once the screw is removed. 11.
You will now see the inside cover of the Playstation 3. 12.
Find the seven screws that secure the lid on the console. (circled in red)13.
Remove these screws. (
Follow them carefully and separate them from the other screws removed so far)14.
Note that one screw is much shorter than the other.
This is pictures of the upper-left corner of the that.
Keep this in mind in order to re-assembly. 15.
Remove the inner cover.
This can be difficult, so don\'t be afraid to exert some power, but be careful not to destroy anything. 16.
Pay attention to the gray Blu-ray drive and the black internal power supply. 17.
There are three wires connected to the power supply.
Disconnect these. 18.
Remove the four screws at the corner of the power supply. (
Track these again)19.
Remove the power supply.
There is a plug attached to the power supply on the motherboard, so don\'t worry if it feels a bit \"stuck. \"20.
Disconnect the wire plug from the Blu-ray drive. 21.
Lift the drive and pay attention to the ribbon below. 22.
Flip the black plastic switch at the end of the ribbon to release it. (
See the second attached picture for the location. )23.
Remove the Blu-ray drive. 24.
Find and disconnect the wires connected to the green battery pack. 25.
Remove the two screws that fix the metal mesh and place it on one side. 26.
Next to the grid section is the second metal plate.
Remove the screws fixed in the appropriate position and place them on one side. 27.
There is a very small circuit board next to the capacitor on the back of the Ps3.
Remove the screw that presses it. 28.
The black wire is attached to this board.
At the other end of the wire is the plug connected to the middle
Board size.
Disconnect this wire from the middlesized board. 29.
Disconnect the silver ribbon of mid
Size circuit board covering large metal plates of the motherboard. 30.
There are two inclined metal parts that are connected with two large screws.
Remove these using a larger cross screwdriver. 31.
There are eight screws pressing the board on the motherboard.
Six are the same and the two are smaller at the top of the picture. 32.
Remove these screws. 33.
Remove the large metal plate.
The motherboard should be exposed now.
Your Playstation should be similar to the second photo. 34.
The motherboard and radiator can now be removed from the housing.
Hot paste that connects the CPU/GPU won\'t show up very easily, but don\'t worry if you hear it breaking. 35.
Rub off the hot compound on the CPU/GPU on the motherboard, in which case the square radiator still exists.
Try to avoid scratches, but remove them as thoroughly as possible. 36.
Connect the motherboard to the last screw of the main radiator (metal part).
Remove this and separate the two parts. 37.
Warm up the oven to 400-
450 degrees Fahrenheit
This is hot enough to melt solder but not damage other parts. 38.
Place the motherboard on the cookie sheet. (
Make sure the board is level.
The easiest way is to place the plate on the raised edge of the paper and the plug is in contact with a smooth flat metal surface)39.
Carefully place the cookie slices on the motherboard in the oven for 10 minutes. 40.
After ten minutes, turn off the oven and open the door. (
Do not touch paper or motherboard)41.
Wait at least 30 minutes to harden the solder.
It is very important that the circuit board is not disturbed during this process, because it may destroy the structure of the welded ball grid array. 42.
Take your hot paste as soon as everything cools down. 43.
Apply the hot paste to the square radiator at the bottom of the console to remove the motherboard. (
There are many ways to apply paste.
I suggest you find one you like online. )44.
Reconnect the motherboard to the radiator. 45.
Using the hot paste now ready, carefully return the motherboard/radiator combination to its position in the base. 46. Re-
Assemble the Playstation 3 back from dis
Assembly direction. 47. Once fully re-
Once assembled, connect the console to the TV and turn it on.
Hopefully you will encounter a console screen instead of a devastating flashing red light. 48.
Allow the console to run and cool down several times before trying to play the game.
Simply leave the system idle and even watch Blu-ray movies to achieve a less demanding cold and hot cycle of the system.
