Baby !

Hi,

Just had my little girl this morning !

So things will take me some more time !!!!

Power supplies study

Hi,

I will first start with the bottom side of the board which is mostly dedicated to power supplies generation and distribution.

On the following picture I've outlined various sections :

First we have the power supplies dispatchment which is mainly creating several supplies plans from the initial supply, starting with a ferrite bead which can serve as a fuse, some filtering with a inductor and a big output capacitor.

Secondly, there are secondaries voltages generated with regulators which are located in regulator sections 1 and 2.

And finally, a BA5888FP motor controller chip.

I will provide, as I finished them, analysis and schematics for these 3 sections.

A) Power supplies dispatchment

Here is a close up of the power supplies plans and components :

B) Regulator section 1

Here is a close up of the regulator components :

Next is a design taken from the TPS64201 Step down controller's datasheet, which is implemented by SONY on the board :

C) BA5888FP section

Here is a close up of the Motor driver IC :


This is based on the following datasheet diagram of an equivalent component :

Ok, schematic tool in place !

Schematics available as soon as I edit them !

Coming soon .....

Study board

Hi,

From now the board used for tests and measures will be the BMD-002 Rev 3

Blue Ray board made accessible

Hi,

On this picture you have the bottom face of the PS3 Blue Ray Drive's board controller :

Here the BMD-001 Rev1 board :



Most of the components can be accessed on their pins to put an oscilloscope probe, except the main processor SONY CXD5065GB-1 (BMD-002 board) or CXD5063AGG-1 (BMD-001 board), and the flash memory SPANSION AL008D0043-01 (BMD-002 board) or S99-50111-001 (BMD-001 board), because they are BGA.

So I had these components taken out to have access to their signals on the PCB :

Here the BMD-002 Rev 3 board :



So now I can do some reverse engineering on the schematics !

Board components

Hi,

I found a list from internet (can't manage to print it here !), it seems to be for a 60 Go version.

It is a very good start to have a component view of the board.

Only few components are not identified and I can't find any datasheets because they are SONY's components.

Hum, there seem to be several boards and several revisions for each board !!

I identified a BMD-001 and a BMD-002 board, are there others boards ?

For BMD-001 we have :

- ASIC / CPU / Video Decryption Device

Rev 1 : CXD5063AGG-1

Rev 2 : TBD

Rev 3 : CXD5063AGG-1

Rev 4 : TBD

- ASIC

Rev 1 : CXD5064R

Rev 2 : TBD

Rev 3 : CXD5064R

Rev 4 : TBD

- Interface controller

Rev 1 : CXA2720R

Rev 2 : TBD

Rev 3 : CXA2720R

Rev 4 : TBD

For BMD-002 we have :

- ASIC / CPU - Video Decryption Device

Rev 1 : TBD

Rev 2 : TBD

Rev 3 : CXD5065GB-1

Rev 4 : CXD5065GB-1

- ASIC

Rev 1 : TBD

Rev 2 : TBD

Rev 3 : Suppressed

Rev 4 : Suppressed

- Interface controller

Rev 1 : TBD

Rev 2 : TBD

Rev 3 : CXA2720R

Rev 4 : CXA2720R

If anyone has technical information on these it would be great to share !

If you can help me filling the missing references that would be great.

As I'm filling this list in time, it seems that there are two board generations with the same main components. On the BMD-002 version, the CXD5064R ASIC and the CXD5063AGG-1 CPU were merged into the CXD5065GB-1 CPU.

PS3, Blue Ray Board Analysis

Hi,

I'm French but I will try to do this in English so everyone can understand !

My goal is to get a good knowledge of the PS3's Blue Ray Controller board in order to ease repair or more !

So here is the amount of work there is to do :

- Reverse ingeneering on the schematics
- Understand board synopsis
- Understand security principles
- Components identification
- Provide blue ray drive work explanations
- And more....

This list will change in time, depending on what I find, information I get and support you will provide me !

So any technical data are welcome.

Cheers !
