THIS GUIDE IS PURELY FOR RESEARCH AND EXPERIMENTAL PURPOSES
USE THE SYSCON UART DIAGNOSTICS FIRST TO CHECK THE ERROR CODES ON THE BOARD, BEFORE PROCEEDING, FOLLOW AT YOUR OWN RISK AND USE IT ONLY IF THE ERRORS MATCH!

The NEC/TOKIN Capacitors have the serial number 0E128 - 1200uF "Phat Models" and 0E108 "Slim Models" - 1000uF Capacitance respectively.
The problem with the use of these Capacitors on the PlayStation3 is that they are 8 "Phats" and 4 "Slim", and they work in tandem to filtre and provide the necessary current to the RSX and CELL, and if one out of the four NEC/TOKIN fails on either of the chipsets, there is a current disruption,which means the Capacitence needed to feed either the CELL or RSX is below the required, thus YLOD.
In this tutorial, ill explain step by step,how to replace the NEC/TOKIN Capacitors and where to start, so dust off your old PlayStation3 from your closet and lets get to work!
DISCLAIMER - Do this repair at your own risk, i am not responsible if your PlayStation3 catches fire or blows in a Thermo - Nuclear fashion, proccede with the upmost extreme caution, read the instructions carefully, and good luck!
*TOOLS - What you will need?
*Soldering Iron - "Small/Thin tip recommended"
*Soldering Flux
*32 Tantalum Capacitors "330/470uF - 2.5V/6.3V - Rated"
*Soldering Skills
*Knife "NEC/TOKIN Removal"
*Cup of Coffee "Optional"
*Patience and steady-hands "recommended"
*Compatible Models:
*Phat Models: "470uF"
*DECR-1000 - "TMU-520"
*DECHA00A - "COK-001"
*CECHA - "COK-001"
*CECHB - "COK-001"
*CECHC - "COK-002"
*CECHE - "COK-002/W"
*CECHG - "SEM-001"
*CECHH - "DIA-001"
*CECHJ - "DIA-002"
*CECHK - "DIA-002"
*CECHL - "VER-001"
*CECHM - "DIA-001"
*CECHP - "VER-001"
*CECHQ - "VER-001"
*DECR-1400 - "DEB-001"
"Due to the DEB-001 being identical to a DYN-001 Board, only the RSX needs a capacitor repalcement, you can use either 470uF, although 330uF will work just fine"
*Slim Models: "330uF" - RSX Only
*CECH-20XX - "DYN-001
*STEP 1 - DISASSEMBLE YOUR PLAYSTATION3.
This procedure its very simple, just like replacing the thermal paste, disassemble your PlayStation3, we will only need to work on the motherboard, for the time being we only will work on the RSX, on the top layer of the board, just one capacitor its needed to replace for the console to boot, if it fails, then more its needed,but the process its the same,but for now we will just focus on one NEC/TOKIN.
*STEP 2 - REMOVE THE ORIGINAL NEC/TOKIN CAPACITOR
Once you have the motherboard in your work-bench, identify the NEC/TOKIN Capacitor, then use a Knife, and carefully remove the original NEC/TOKIN Capacitors, they have a Plastic Outer-Shell so removing them should be pretty easy, i suggest using a masking tape as there are many traces around the NEC/TOKINs, you can also use the Soldering Iron to melt, the Plastic Case, as it will be even easier to remove them, remove the capacitor until you have four solder lines "2 Positive/2 Negative", that means the capacitor its completely removed. "See the picture for reference"
*STEP 3 - SOLDER TANTALUM CAPACITORS IN THE POSITIVE/NEGATIVE POLE.
This its a very important step, there should be four solder lines once you remove the NEC/TOKIN Capacitor, the Tantalum Capacitors have a Positive Pole and a Negative Pole, the Grey Sign its your Positive Pole, the rest of black its the Negative Pole, the 2 Middle lines "almost together" are your Negative Poles, the other 2 from the start are your Positive, you need to solder 4 Tantalums in the correct order, solder them in a 65º Angle, in order to fit 2 Tantalum Capacitors in 2 lines "Positive/Negative", its important while soldering that the legs of the Capacitor touch they´re respective rails "Positive/Negative". "See the picture for reference"
*STEP 4 - ISOLATE THE CAPACITORS
After you done soldering all the four capacitors, grab some electical tape,and isolate the Tantalum Capacitors, this will make sure that the Solder from the Tantalums wont touch the EMI Sheild "Electro Magnetic - Sheild" thus creating a short, after that assemble the PlayStation3, and test the console.
*STEP 5 - TEST THE UNIT
If all has been done correctly, your console should boot without any problems, Congratulations you just fixed your PlayStation3, if your console refuses to boot, inspect,and make sure you solder them right, take a look carefully,and test it again, if it still refuses to boot,then more capacitors replacement its needed, replace the 2nd NEC/TOKIN with Tantalums on the RSX Area,where you replaced the NEC/TOKIN area before, the procedure its the same.
"IMPORTANT - TO MAKE SURE YOU DID IT RIGHT, AND MORE CAPACITORS NEEDS REPLACEMENT, THE YLOD MUST BE DELAYED, SOMEWHERE IN BETWEEN 3/5 SEC TIME-FRAME, IF ITS IMMEDIATE/SHORTED THAN THAT, IT MEANS THAT THE CAPACITOR ITS NOT PROPERLY SOLDERED, THAT HAPPENS WHEN A NEC ITS REMOVED,BECAUSE THERE IS NO CURRENT SUPPLY TO THE CHIP"
"NOTICE - IF YOU ARE PLANNING TO REMOVE THE NEC/TOKINS, I SUGGEST TO LEAVE THE ORIGINAL NECS UNDER THE BOARD, AS THEY HAVE AN INTERNAL BRIDGE/JUMPER ON THE POSITIVE POINT, SO IT WILL CREATE A BRIDGE FOR THE TANTALUMS, BUT IF YOU DECIDE TO REMOVE ALL THE NECS, YOULL HAVE TO BRIDGE THE TANTALUMS FROM THE POSITIVE TO POSITIVE POINTS WITH A HIGH GUAGE WIRE OR ELSE THE CURRENT WONT PASS THOUGH,SINCE THERE IS NO BRIDGE BETWEEN THE TANTALUMS! BUT THE BEST WAY TO AVOID MAKING JUMPERS IS TO LEAVE AT LEAST 1 ORIGINAL NEC ON THE MOTHERBOARD "See Picture for Reference"
