Use this guide to replace a blown motherboard. Replacing the motherboard requires removal of nearly every component in your PS3.

  1. Use the tip of a spudger to remove the black rubber screw cover from the side of the PS3.

    • Be sure to keep track of the small metal bracket loosely held in the top cover, if equipped.

    That small metal bracket/socket set up looks completely different in the ps3 I'm working on. Model: CECHK01.

    Any suggestions?

    • Remove the following seven screws:

      • Six 52 mm Phillips screws

      • One 30 mm Phillips screw

    2 more smaller screws (don't know what size...small) just below the top middle screw and top right screw (in the picture). Look for the arrows...

    after you remove the screws, you may have to push a tab to take the cover off if you meet resistance on one side of the cover. Here is a link to a video that explains it, saved me lots of trouble:

    1st attempt, fan loud. Ps3 lasted about 2 wks. 2nd attempt noticed very poor contact between heatsink & cpu,gpu when taking it apart. Research - Found a better way to apply thermal past. I personally disapprove of guide on this. A small bit about the size of a grain of rice in center of cpu is plenty. Clamp the heat sinks back on. Then take it apart & check contact area. Thermal paste should have spread to about the size of a quarter.(more is better. Less then a nickel size is poor contact) possibly weak clamps. Carefully applied pressure onto the cpu & gpu, pressing them into the heatsinks before clamping heatsink clamps on. Achieved greater then quarter sized thermal past spread. Fan silent in comparison & ps3 lasted about a yr. Rarely did I ever hear the fan go to high and get loud after that. About to begin my third fix on this same ps3. One of the first 80g backwards compatible. other then those notes and that this guide was for a different model ps3 (minor differences) I liked this guide. easy to follow.

    Although the battery is described as proprietary, it looks like it is the common CR2032 lithium coin battery that is used in calculators and some computers. I haven't had to replace mine but I suspect under the heatshrink cover is a battery holder which will allow the coin battery to be removed and replaced. Then wrap with electrical tape and reinstall.

    I tried this with the heatgun and it ruined my PS3. The CPU and GPU are NOW RUINED!!! It did not work for and made things worst!!! I sent it to a place to get reballed and they said the HEATGUN had overheated my processor and killed them!!! So think twice about doing this. Just because it is already broken, DON'T THINK YOU CAN'T MAKE IT WORST!

    Why would you try it with a heat gun, no were is it mentioned to do that

    There are 2 additional screws to remove , front center and front left , just behind the already marked screws.

    As mentioned and I’ll add so detail too. If you have a model with the card readers there are two more small screws that also need to be removed before moving on to the next step.

    • Lift the top cover from its rear edge and rotate it toward the front of the PS3.

    • Remove the top cover.

    • There is a plastic hook located in a hole on the top back right hand side corner. Carefully push the plastic hook a bit front the rear of the machine with a spudger to release the rear right of the casing.

    Disconnect the memory card ribbon cable.

    The top would hardly budge on the left back corner and was stuck on the right back corner. There is a plastic hook that needs to be unfastened to lift the top off. It is located in a hole on the top back corner on the right hand side, so the corner straight across the on off button. Just gently push the plastic hook a bit front the rear of the machine with a spudger. It gives easily and the top will be free to lift off after that.

    Some more details here as well.

    The newer model without SACD support appears to have added that clip to the back right that needs to be pressed to release the top shell.

    If equipped with the card reader you can either have to disconnect the ribbon cable or unclip the reader from the top shell after lifting it up to get finger or tool in there to push clip to side and release reader from top shell. Note: if you failed to remove the card reader screws in the previous step these clips can break.

    • Use your fingernail to flip up the retaining flap on the Blu-ray ribbon cable socket.

    • Be sure you are prying up on the retaining flap, not the socket itself.

    • Pull the ribbon cable out of its socket.

    • Remove the Blu-ray drive from the PS3.

    • If replacing the Blu-ray drive, transfer the power cable to your new drive.

    Not all systems look like this, some have tape instead of the flap.

    Every system that I have seen has had the ZIF connector, while some had tape over the connection as well. If your connectors are taped, be sure to remove the tape, then proceed with undoing the ZIF connector.

    Brett Hartt -

    The version 2 systems baseboard PCB started switching to the new narrow 24 pin ZIF header/ribbon and Blu-Ray drive connection.

    You should not attempt to detach the taped ribbon cable from the drive end first as described above for the older wide 60 pin ribbons. You must remove the drive and ribbon as one unit to protect the fragile ZIF sockets.

    The slimmer fragile ribbon is taped to the drive housing to afford a more secure ZIF connection. The opposite base connection is slightly under the PSU.

    One should firstly remove the PSU: Disconnect the drive power cable as described above. Unscrew the 5 (3-P1 2-P2) PSU mounting screws. Now leaving the power cables attached, lift the PSU off the power baseboard PCB pins and move over slightly to access the baseboard drive cable end ZIF. Release the ZIF latch and slide the entire (drive and ribbon) strait away from the baseboard ZIF to disconnect.

    After the complete drive/ribbon removal, you can carefully remove the restraining tape on the bottom of the drive to release the ribbon ZIF, then remove the 24 pin ribbon from the drive logic PCB.

    Install in reverse order making sure to add new tape to secure the ribbon to the drive.

    shadetree - Reply

    I needed to remove the PSO completely to reach the baseboard drive cable end ZIF. To do that disconnect the power and data (I assume) cables and then pull the unit straight up. To longish prongs are heading straight up into it from the baseboard and it is a bit tight, so gently pull until it's clear.

    If you are replacing the Blu-ray drive, you must use the same daughterboard that came with your PlayStation 3. The daughterboard is paired to the motherboard, and the Blu-ray drive will not work with a different board. -------------- I understand however my daughterboard is not on the bottom of the blu-ray drive it must be on the inside. Is there any advice out there on how I go about doing this as I am not sure what I am doing???? If someone could post a link or any tips it would be greatly appreciated.

    When I received my new drive there was a sheet that said you could keep the old boards but you have to 'flash' them with the ps3's digital information. Currently trying to figure out how.....

    • Pull the control board ribbon cable straight up and out of its socket on the motherboard.

    Some PS3 versions do not have a separate control board, since the buttons and LEDS are located on the motherboard (for example, in my PS3 model CECHG04). In this case steps 10, 11 and 13 are not applicable.

    • Lift the motherboard assembly out of the lower case.

    My Ps3 was a little different..

    The rear backing plate is connected to the fan shroud beneath the unit that is screwed into the bottom of the case.. And these large chrome pieces attatched to the fan were stuck to the tray that the board is on. Came a part pretty rough, guessing the ps3 got so hot it turned the grease into glue lol

    intotec239 - Reply

    If you already suspect you may have a slightly different PS3 model to the one pictured here STOP RIGHT NOW! Do not try and lift the motherboard off the lower casing if it is not coming easily. On mine, the cooling fan and heat sinks have extra screws directly into the lower plastic case and you will not be able to lift the motherboard out until after you have done Step 27. So skip this step, continue through the guide, skip 18-23 (you probably don't have a memory card reader). After unscrewing the 4 screws in Step 27, pull hard to separate the motherboard from the heat sinks (they will be attached with thermal paste like a glue). Only then will you be able to access the screws to separate the large fan and heat sinks from the plastic lower case.

    Incidentally I totally smashed mine trying to get the lower case off here at step 15 - I broke the screws off, warped the metal on the heat sink and snapped pieces of plastic. But I continued and did the heat gun stuff and it still actually worked!!

    • Remove the 7.7 mm Phillips screw securing the ground strap to the chassis.

    On my PS3 the ground wire(green/yellow) was actually routed under the bolt for the power supply, so I had to remove the power supply before I could removed the AC inlet

    Had to remove 2 screws (the top 2 screws marked in step 25) to get the ground cable out.

    Like @asciimo and @deuxphoria, I had to loosen the same two screws to get the ground wire out. When you're putting the PS3 back together and you're doing the steps in reverse, it helps to leave those two screws unscrewed during Step 25 and wait until you put the AC inlet back in Step 18.

    hogurt - Reply

    You can put the 2 screws back in step 25, just put the AC Outlet before you put in the back plate. (Do Step 18 before step 19 when you are going in reverse)

    xaviertaylor - Reply

    • While lightly pulling the rear cover away from the logic board assembly, use the flat end of a spudger to release the clips along the top and bottom edges of the rear cover.

    If going in reverse do this step after step 18, otherwise you will have hard time getting the earth cable routed.

    • Remove the two 9 mm Phillips screws securing the memory card reader to the chassis.

    Only the very first release of the PS3 used to have the memory card reader. Most recent models do not have it (such as my PS3 model CECHG04). In this case just skip steps 22 and 23.

    Also, these screws should be removed in step 5 to prevent breaking the clips that secure the card reader to the top shell.

    • Lift the memory card reader out of the PS3 enough to access its ribbon cable.

    • Pull the ribbon cable out of its socket and remove the memory card reader.

    I have a CECHA01 and the card reader is attached to the top cover. Per comments at step 5, the 2 screws mentioned at step 22 are removed at step 5. The ribbon cable mentioned here in step 23 should be removed at step 5.

    • Lift the motherboard assembly off the heat sink.

    • The heat sink may still be held in place by the thermal paste. If this is the case, gently pry the heat sink away from the motherboard housing. Make sure to not bend the copper piping on the heat sink.

    • Be sure to apply a new layer of thermal paste when reattaching the heat sink.

    • Never applied thermal paste before? Our thermal paste guide makes it easy.

      • If you're following the YLOD repair guide, stay tuned for where to apply the replacement thermal paste.

    so do we apply arctic silver 5 thermal paste to the heat sink pads that attach to the CPU GPU,Or do we only apply thermal paste to the chips /pads CPU GPU ?

    David - Reply

    In some PS3 versions, such as my PS3 model CECHG04, the heat sink is attached to the lower half of the motherboard shield, so in order to remove the motherboard you have to lift the top cover and detach the motherboard from the heat sink.

    On my 60GB model, the Blu-ray ribbon cable was very easy to disconnect, but a real pain to re-connect. It's not as easy as pushing the black fap down to secure the ribbon. This YouTube video helped enormously:

    • Disconnect the PRAM battery from the motherboard.

    • The PRAM socket is delicate and has the potential to break off the motherboard. If possible, hold down the socket as you disconnect the PRAM battery cable.

    In the most recent PS3 versions, the PRAM battery is located on the motherboard: remove it before performing the reflow and don’t forget to put it back before starting the re-assembly.

    markp - Reply

    • Rotate the PRAM battery slightly counter-clockwise and remove it from the motherboard assembly.

    It is quite hard to rotate counterclockwise, but by rotating it slides out, no pulling up is needed. Hard to do by hand, but much easier if you use some flat nose pliers.

    jerseyzangel - Reply

    Same here. Even with pliers, my PRAM battery was incredibly difficult to remove. When it did finally come loose, part of the black plastic that keeps it secure broke off for me. The whole thing is loose now when I put it back, but still stays in place.

    hogurt -

    Worked. Took 3 hours to complete.

    ****NOTES that weren't mentioned here****

    1. Heat Gun on processors = zigzag from top left to bottom right - then circle back up to the top left. repeat.

    2. No thermal pads available in your area?

    I used the same thermal pads that came with the PS3

    3. No T-10 security screw driver?

    I broke the very first step - I didn't have a t10 security driver and jsut figured I would risk breaking the cover a bit by pulling it straight up - popped right off - then broke the stupid screw right off of it.

    4. took 15 minutes to find things to ensure the motherboard we perfectly level.

    5. I let the Motherboard sit for exactly 17 minutes and then applied Arctic silver.

    6. No Screwtray ?

    I used a piece of duct tape, sorta flipped it around so it was a sticky pad to grab all the screws and not let them get unorganized.

    I hope I remember to report back how long the system runs until it dies again, which I hear happens fairly quickly after this type of operation.

    Good Luck.

To reassemble your device, follow these instructions in reverse order.

Just fixed my YLOD last nite and it works like a charm! best guide on the internet, and it was free! i bought the kit here and it has everything you need minus the gunk off. One thing I'd like to see is how to organize all the screws... I had 2 left over after reassembling the unit. it'll also be nice if the guide showed you how to put certain parts back on (back case, top case units).

It took me a total of 3 hours to do. Not bad considering I don't tear things apart for a living.

other than that, the guide and kit are awesome!

Just fixed my PS3 Fat. It's the only one that plays PS2 games so it was hard to part with. Instructions were easy to follow. However, I didn't replace the pads on the chips. PS3 is working beautifully again and the fan is much quieter now. I kept forgetting screws and the WIFI cable so I had to take it apart at least a few more times. Now I can take apart and reassemble the PS3 in my sleep.
