How to Reflow a PlayStation 3

Last Updated: November 3, 2023

Many original models of the PlayStation 3 have hardware issues that eventually causes the system to overheat after years of use. The infamous "Yellow Light of Death" will turn on when this occurs which makes the console no more useful than a paperweight. The warranty on most of these consoles have expired, so the two options you have are to either to pay a decent amount of money for a professional to look at it, or to take the matter into your own hands. These instructions will show exactly how to do the latter.

1
Gather your supplies. There are some simple necessary tools that you will need:
- A Philips head screwdriver
- A heat gun (300 °C)
- Thermal Paste
- T8 Torx screwdriver

2
Remove HD Drive. On the side of the unit you will find a panel with the warranty sticker. Once off you will see it is held in place by a blue screw. Remove this screw.
- Use the pull tab on the hard drive to remove it out of the unit by sliding it forward and then pulling straight out.

At the top of the unit there is a rubber tab covered by another warranty sticker. (Yes, you will be removing the warranty sticker and voiding your warranty. You’ve been warned.) Under this cover should be a screw. Remove this screw and the top will slide off.
{"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/0\/0e\/Pic6.jpg\/460px-Pic6.jpg","bigUrl":"\/images\/thumb\/0\/0e\/Pic6.jpg\/728px-Pic6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

Now with the outer shell removed your unit should look like the image above. Remove the screws from the highlighted areas. Now the top support is free. Be cautious as there is a ribbon cable that connects it to the main unit! Remove this part from back to front and then disconnect the mentioned cable. You can now set this part aside
{"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/f4\/Pic7.jpg\/460px-Pic7.jpg","bigUrl":"\/images\/thumb\/f\/f4\/Pic7.jpg\/728px-Pic7.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

5

Disconnect the Blu-ray player. Now you should start to see the inner workings of your PS3. On the right hand side of the unit is the Blu-ray player with a wire running to the front center as shown. Unplug this wire and gently lift the player. Underneath the player is a ribbon cable. Gently reach under and disconnect this cable and set the Blu-ray player aside.
{"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c5\/Pic9.jpg\/460px-Pic9.jpg","bigUrl":"\/images\/thumb\/c\/c5\/Pic9.jpg\/728px-Pic9.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

6
Unscrew the antenna wiring. Behind where the Blu-ray player used to be you will find a chip, which must be unscrewed.
- This chip has a wire which runs down the center of the assembly and plugs into another chip. Unplug it from this chip and set it aside.
  
  {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/f3\/Pic10.jpg\/460px-Pic10.jpg","bigUrl":"\/images\/thumb\/f\/f3\/Pic10.jpg\/728px-Pic10.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

Above the chip that you just unplugged the wire from is the power supply. A set of wire plugs is just between these components and must be unplugged. After removing the 4 screws that hold the power supply down, lift the component straight up. Pins run up into the power supply and you don’t want to damage them. Now you can unplug the back cables from the power supply and set it aside. ^{[1]

Unplug the ribbon cable from the chip that was in front of the power supply. Four screws hold this chip to the rest of the unit. Remove them and set the chip aside.
{"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/6\/66\/Pic15.jpg\/460px-Pic15.jpg","bigUrl":"\/images\/thumb\/6\/66\/Pic15.jpg\/728px-Pic15.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

At the front of the unit where the power button normally is found, is a tiny ribbon cable that arches over the metal plate on the motherboard, which we will soon be removing. Be sure to unplug this cable by flicking the tab (closest to the front) forward and lifting the cable out.
10
Remove the next set of screws.
- On the plate that is connected to the motherboard are arrows pointing to screws. Remove these screws.
  
  {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7c\/Pic16.jpg\/460px-Pic16.jpg","bigUrl":"\/images\/thumb\/7\/7c\/Pic16.jpg\/728px-Pic16.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
- Four more screws attach two plates to the motherboard. Remove these screws as well and set the plates aside. Be careful from here on out, as the plate will not be attached to the motherboard directly.
  
  {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/3\/39\/Pic17.jpg\/460px-Pic17.jpg","bigUrl":"\/images\/thumb\/3\/39\/Pic17.jpg\/728px-Pic17.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

The motherboard and fan assembly should now freely lift out of what remains of the casing, careful though as these come as 2 separate parts.
{"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/8\/82\/Pic21.jpg\/460px-Pic21.jpg","bigUrl":"\/images\/thumb\/8\/82\/Pic21.jpg\/728px-Pic21.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

Lift the top plate from the front and it will slip out of the back. Set the top plate aside.
{"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/d\/d4\/Pic19.jpg\/460px-Pic19.jpg","bigUrl":"\/images\/thumb\/d\/d4\/Pic19.jpg\/728px-Pic19.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

13
Remove the back plate. Unscrew the ground wire from the frame. Now gently pull the back plate away from the main unit and set it aside.
- Flip the unit over and you will see a little green battery attached to the bottom plate. Unplug this from the motherboard that is underneath. Opposite the battery is the plug-in for the fan running into the motherboard. Unplug this as well.
  
  {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/f1\/Pic23.jpg\/460px-Pic23.jpg","bigUrl":"\/images\/thumb\/f\/f1\/Pic23.jpg\/728px-Pic23.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
- The HD bay can be seen jutting out from the bottom of the bottom plate. Unscrew this and set it aside.
  
  {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/3\/30\/Pic25.jpg\/460px-Pic25.jpg","bigUrl":"\/images\/thumb\/3\/30\/Pic25.jpg\/728px-Pic25.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
- The ports for the inputs are attached to the bottom assembly as well. Go ahead and remove those and set them aside. The bottom plate should now lift away from the motherboard and take the fan and heat sinks with it. Set it down with the fans on the top side as you will be working on it shortly.
14
Clean the CPU and GPU. You can now see your CPU and GPU (the two big squares in the center of the motherboard) with the old thermal paste on them. Using a paper towel gently rub the paste off of their surface, being careful not to scratch them. ^{[2]

Clean the heat sinks, too. Do the same for the heat sinks that make contact with the CPU and GPU that are on the back plate that we set aside. ^{[3]

Place the motherboard with the CPU and GPU face up and as level as you can manage. Using the heat gun, apply heat to the CPU and GPU. You want your heat gun to get to roughly 300º C and wave it around 3–4 inches (7.6–10.2 cm) off the surface of each component. You are looking to melt the solder inside these components so the point is to get them really hot. DO NOT MOVE THE BOARD now that it is hot. Doing so will ruin your PlayStation past the capability of this repair. ^{[4]

Research source} Let it sit for 15-20 minutes as it cools and the solder solidifies.

Apply the thermal paste to the heads of the GPU and CPU. Spread the paste evenly on the surface with some sort of scraper, anything will do. (Note previously we put the paste on and then heated the GPU and CPU. This isn’t good practice, so it's not recommended, but it worked out anyway in this example.) ^{[5]

Reassemble the PS3. That’s it! You’re done. Now all that is left is to do is to follow the assembly steps backwards and test it out. In our trials we were unsuccessful with the first try but the second reflow did the trick. Good luck!

Question

How long should I heat up the chips?

Community Answer

For about two minutes, depending on how quickly your heat gun gets hot. If it's older and slower, then about three minutes will do the trick. If it's a better and hotter heat gun, then something more like one minute would be good.

Question

I did this trick but its still the same. What should I do?

Kaylyn Holmes

Community Answer

Maybe you didn’t heat the solder enough, or it could be the chip itself. Try again, but after the third time, send it to Sony. Heating it too much could damage the chip.

Question

How reliable is this method of reflowing the solder?

Community Answer

It’s not incredibly reliable, though it is helpful if somebody doesn't know more about electronics.

Choose a decent thermal paste, more likely paste better than what comes in the system. Arctic Silver 5 is your best bet.

Mind the silver ribbon cables. These cables are small and thin, so if you tear them, your PS3 will be irreparably damaged.

Be careful in handling each component of the console. There are many delicate parts on the motherboard that can easily be damaged if proper care is not taken.

Thanks

The process may have to be repeated more than once before it is successful. If this still does not work, bring your console to a professional. There is a good chance the console is irreparable.

Thanks

Don’t do this more than 3 times. Otherwise you could damage the CPU and GPU/RSX’s internal dye and render your PS3 system damaged beyond repair.
