The right blu-ray logic board?
The right blu-ray logic board? –
How do you know if the logic board is the one matched to your motherboard?
The reason I ask is that I bought a PS3 that needed a new blu-ray drive. The PS3 came with a hard drive and logic board attached to non-working Blu-Ray.
I bought a Blu-Ray that was apparently working. I fitted the logic board to it, fired up the PS3 and the Blu-Ray drive will not accept discs.
Tried holding the eject button down and switching on from the rear rocker switch for 10 seconds. Blue light flashes but still no taking in of disc.
Swapped the main cable from motherboard to drive as well as the power cable.
Rechecked all the connections. Nothing.
I stripped both drives down to check the gearings etc. The broken drives gears were not right so I re-seated all as it should be. Still nothing with both drives.
The only thing I haven't checked is the logic board.
Once you get the blu-ray drive to accept a disk, you can tell if the logic board is the right one, because you get a small little busy/loading symbol, the old swirly blue disc next to the time, or on the new PS3 v3.01 update, the turning analog clock hand, once it sees a disc.
If the logic-board is not the right one, then the swirly blue disc will never appear, or the analog clock hand will not move like a sweeping second hand.
Thanks for the swift reply garyopa (loved your work on the xbox360 btw). I had just been testing the PS3 on the bench rather than with the TV. I shall hook it up to the TV and see if I get any more clues.
I thought that I would get a cheap PS3 to 'play' with. This is proving a challenge but I have learnt so much more about the PS3 innerds. Now I am curious as to where the key is stored on the logic board (not that I am any programmer or electronics wiz). Can the board be spoofed as per xbox360? At the moment this is great fun!
(I should probably get out more :-) ).
It is stored in 16megabit (2megabyte) flash chip made by SPI, it is small 48pin BGA device, but it has been proved that you can swap this chip, and you are re-married, so for sure the key is in this chip.

I been working on a project to decrypt and fiqure out the signing,pairing system, plus being able to flash/read it without removing this tiny 48pin BGA device, but it is not finish yet and in the very early stages of development, so don't even one hold their breath.
Also there is at least four different designs of the Sony blu-ray drive, the first one (single-eye), the second one (dual-eye), the third SATA interface, instead of the old IDE design, and the newest fourth smaller SLIM board.
Hi garyopa. Sorry I didn't get back to you sooner.
That is very interesting about the storage of the keys.
I was also wondering why people were selling the drive logic board on its own. Now it makes sense.
I thought that you may have been delving into the key encryption! I should imagine it is the Holy Grail for the PS3.
You don't make things easy for yourself though, 48 pin BGA. Where do you start??
The best of luck with that. If anyone can, you can.
You might be able to help me on a diferrent matter. I took a chillyfix off a 360 drive that had been wired up wrongly. Is there a way of checking the chip, before using it on another drive?
Use a ohm-meter and check for a small bit of resitance between the power and grounds on the chip when removed from the board (no wires coming from it), and if there is at least 30-40 ohms or higher, then it should be safe to use.

I came across this thread today during a massive Google search. I have been fixing and repairing the original PS3 systems (YLOD problems and bad drive issues for months), and I have a few bad PS3 slim systems(already)... at this point, I really don't know what's wrong with them, so they are just basically good for parts at the moment. 1 system looks like it powers on but never shows any video or even gets to the point where the controller is recognized, so its totally hosed and is either the victim of a bad flash or something else which corrupted the boot sequence.
The 2nd, and more interesting system seems to work fine, with the exception of the drive. When I try to insert a disk, it grinds and chugs but never actually spins the disk or takes the disk in. So, I guess the drive controller board is whacked. When I replace that existing drive with another drive and different drive logic board, the disk spins up, and seems to work fine, but obviously doesn't work due to that drive not being married to the system... so the problem is definitely in the drive control board since a known good board and drive, sucks in the disk, starts the laser, etc.
I removed the slim's drive logic board and did some research today... unlike the old original fatter PS3 systems, the new slim uses a completely different BR drive and different control board. Upon inspection, I see 3 main ICs... 1 proprietary Sony IC (big QFP, not BGA) design, plus 1 48 pin S!P IC (BD7969EFV), and 1 8 pin serial flash device (MX25L1635D). All 3 of these devices are simple surface mount SOP technology, and not BGA... so replacement of a device or remarrying of a different drive logic board should be alot easier on the slim than hte PS3 original--IF the keys are in that serial flash device, which they should be.
I have no idea if my current drive board is failing due to the S!P IC, which is some sort of dvd and BR driver chip. So, this is most likely the problem. However, since I have a completely spare slim (250GB BMD-061) drive control board, I will take the easy way out and swap the 8 pin serial flash from my current drive logic board to a known good logic board from another drive. This operation won't take more than 10 minutes now, since Sony used an 8 pin SOP package. So, this may be good news for people with bad drive controllers, and this should be alot simpler to remarry drives, since the flash chip is not a 48-pin BGA now...
I will report back my findings after I get the chips swapped...
Confirmed... the PS3 slim logic drive board uses an 8 pin SOP serial flash device (located right next to the proprietary SONY bga chip on the PCB), which is waaaaaaaayyyy easier to change than the old original 48 pin BGA flash device. I swapped the chip in about 5 minutes, and had my weird acting drive PS3 slim up and running in about 30 total minutes, which included reassembly.
I don't know why, but the logic boards do seem to go bad, and I am guessing that the S!P drive control chip goes haywire. I haven't measured the signals, but I did find the datasheet for the drive control chip yesterday.... but since I had spare logic boards, I figured it wasn't worth digging into the actual problem too deep...
That's good to know. -- I get some more slim's in to repair, I have to try that. -- I only got one totally dead 120gb model. -- Do you have pictures of scrap 250gb drive board, I wonder if it the same as the 120gb version? -- Sony loves to change designs fast. -- In the stores it is whole new PS3 Slim design now with 40nm RSX, and smaller power supply. -- Ugh!
