Repairing Sony PlayStation 2 Game Console

One of my friend had Sony PlayStation 2 (SCPH-39000 series) game console and in few months back it get fail because of the internal short-circuit due to spill of some liquid over the game console. Finally he sends it to me to repair it, and I found some problems in both PSU (Power Supply Unit) and motherboard of the console.


In first round of the repair I replace IC807 (78M05), PS013 fuse and all the related parts near that area (because I notice some burn marks in that location) except IC806 (NJM12904). Other than that I replace R278 (1.5k), R279 (1K + 100R), R491 to R495 (with wire links), R470 (100K), Q415 (2SC2873), Q406 (IRF7901, I got this transistor from another old PS2 game console main board, available in junk store), F001 (with some 42 S.W.G copper wire) and D404 (with 3 × 1N4148 diodes).


When I replace and re-solder some of the parts as described above, I got the video signal (PS2 startup splash and main menu) from the console. But system may not produce any audio signals (in both left and right channels of audio output). Finally I check the audio part of the system and found that the problem is in final stage of audio DAC (IC517 - Cirrus Logic CS4335 - 24-Bit, 96 kHz Stereo digital to analog convert chip). Once I replace that chip (thanks to old PS2 game console main board which I was purchased from the junk store) this system may get start with both audio and video.


Once the system is up and running I attach the battery and other assemblies to the board and finalize the repairing process.

If someone like to repair Sony PlayStation 2, following points are important to him/her (according to my experiances),
  • Before make any repairs, disconnect the mains supply and battery supply from the main board.
  • Make sure to place insulations sheet between the PSU and Shield B (Shield located at the bottom side of the main PCB).
  • Most of the components of main board are SMDs. So it is necessary to have good SMD Rework Station to carryout any component level repairs.
  • There are several flexible ribbon cables in this system. Handle them with proper care.
  • Do not adjust any potentiometers, trimmers and coils located on the main board, PSU and Optical Pickup.
  • There are several heat transferring sheets are located on the bottom side of the main PCB. (e.g : heat transferring sheets attached to the IC802 - BA5815 and IC803 - BA6664). Make sure to attach them properly when setting up the Shield B.

Well Well Well did some digging in your post and found out that it was a combination of 3guides found on the web........you can do better bro dont talk like you know every dam thing there is to know......just for god sake dont fool good ppl. didnt your mother teach you not to do that?????

CD2003 - yet another simple FM radio receiver

In the last few days, we are looking for some simple FM radio receiver to integrate into one of our ongoing projects. For that, we try several FM radio receiver ICs including TDA7000, CD2003/TA2003/TA8164, CXA1019, and KA22429. Out of all those chips we select CD2003 (or TA2003/TA8164) based receiver for our project because of its simplicity and outstanding performance. Except to CD2003, Sony CXA1019 also perform well but we drop it because of its higher component count. We design our receiver based on Toshiba TA2003 datasheet and later we try TA8164 and CD2003 with the same circuit. Either CD2003 or TA8164 can directly replace TA2003 IC, and as per our observations, TA8164 gives excellent results out of those 3 chips. A prototype version of CD2003 FM radio receiver The PCB design and schematic which we used in our prototype project are available to download at google drive (including pin-outs of crystal filters and inductors ). Except for CD2003 IC, this receiver consist...

Arduino superheterodyne receiver

In this project, we extend the shortwave superheterodyne receiver we developed a few years ago . Like the previous design, this receiver operates on the traditional superheterodyne principle.  In this upgrade, we enhanced the local oscillator with Si5351 clock generator module and Arduino control circuit. Compared to the old design, this new receiver uses an improved version of an intermediate frequency amplifier with 3 I.F transformers. In this new design, we divide this receiver into several blocks, which include, mixer with a detector, a local oscillator, and an I.F amplifier. The I.F amplifier builds into one PCB. The filter stage, mixer, and detector stages place in another PCB. Prototype version of 455kHz I.F amplifier. In this prototype build, the Si5351 clock generator drives using an Arduino Uno board. With the given sketch, the user can tune and switch the shortwave meter bands using a rotary encoder. The supplied sketch support clock generation from 5205kHz (tuner f...

Calculator for audio output transformers

Audio output transformers are heavily used in a vacuum tube and some (older) transistor base audio power amplifiers, but these days output transformer are quite hard to find and expensive item. For homebrew projects, the best option is to construct those transformers by ourselves and this script helps to calculate winding parameters for those transformers. This " AF output transformer calculator " script is written using Python and it works with most of the commonly available Python interpreters . The script is available to download at google drive under the terms of GNU General Public License version 3.0 . Homebrewed 25k: 4 output transformer Once supplied the input parameters this script provides a winding ratio, the number of turns required for primary and secondary winding and required copper wire gauges for both primary and secondary windings, etc. We construct several AF output transformers based on results of this script, which including transformers for M...
