How to check for matching PS3 & BD logic board?

[CooLJoE]

Title probably makes people say "duh, do this", but here's the issue. The PS3 I have, CECHE01 80gb, doesn't have a working BD drive. I got it from a relative that said the system wasn't working, but thankfully it does turn on and work. The problem is the drive isn't working its looking like I need a new logic board & laser mech. My thought was to try swapping the NAND to a new board (I'm decent at desolder/solder work). However, I can't be sure the drive has the original logic board from the PS3, because they tried to get it fixed and mentioned something about the repair guy trying a new drive in the system. I would just download a demo from PSN, as I've heard even those require a proper matching BD logic board to work, but the FW on the system is like 3.50 possibly 3.4x, so I can't download a demo without updating and don't want to do that since thats a good FW to have in this situation.

So my question is how can I be sure its the original matching BD logic board without connecting to PSN/updating FW, and without using a PS3 game disc since the drive isn't fully working?

I'm not sure how you can check if the logic board is matching, but since your system is on 3.55 or lower you can remarry any logic board from the same model to it. You however won't be able to recover blu-ray movie playback on it. DVD and games willwork however.

you can install a custom firmware and try and run some home brew failing that your lucky enough to be able to downgrade and remarry a new logic board quite easily. just QA flag downgrade to 3.41 then down to 2.30 then run the remarry files. you can be up and running in less than an hour if you wanted sorry i cant help you wft tutorials and files really sort on time but if its laser just install cfw and play games of hdd. if its logic board just buy a second hannd one of ebay for £10 and remarrry easy.

i have one you can buy if you need it.

sorry for my bad grammer rushing

Hate to burst the bubble, but how exactly can he QA flag without FIRST having a married BD board?
Second, (and for the god knows how many times I have said this) you only need to goto 3.15, NOT 2.30

As for the OP, are you sure your problem is not just the laser. If it's toast, it will not even spin up the disc.
If the drive accepts end ejects discs, then your logic board is at least working.
As for the repair guy, I doubt he would have sent out a new board and kept the dodgy one so 99.9% chance you have the original.

Sorry for not responding sooner.

rrelite & pereb - Yeah, trying to avoid CFW since I'd rather make it into a proper PS3. Remarry isn't one I want to do as that will drop BD playback. If all else fails, I might go that route and then do CFW (might as well if BD is lost).

Mark - Its been awhile since I did all the cross checking with another PS3's BD drive (I have a full working 60gb PS3 CECHA01), but I do know this one doesn't like accepting discs. The sensor (on triangle board) detects a disc (turns it on when beam interrupted), and the switch to detect the tray is in works, as it allows the eject button/light to do its deal in each position. But the switches to actually make it pull in a disc (2 standing upright) don't do anything, no reponse. Seems like the motor that drives the pull-in mech has gone or the chip that talks to the motor has issues. Using this BD board on a working drive has the same reaction, the disc never spins up. I do remember seeing the laser light up, but no disc sping up, so something in that area has also gone. My hope is the NAND chip is still ok so I can swap it to another BD drive, which then would give me a proper PS3 (no remarry or CFW needed), but thats where I'm stuck cuz I can't be sure its the original, and I don't want to shell $40 for a drive only to find out the NAND isn't the original. I'm guessing it is the original, cuz as you said its not likely a repair guy would keep a dodgy drive/board and send a PS3 back with a good one especially when it didn't fix the PS3.

Found my notes and here's the basic rundown:

RECAP:
- CECHE01 turns on, but bluray drive doesn't function. eject button beeps and flashes blue light
- drive set in "disc in drive" position with disc set inside does not spin up or do anything
- horizontal switch on triangle board that lays flat and is triggered by mechanism position functions telling whether disc is in drive or not (enables or disables beep/light reaction of eject button)
- vertical switches (the 2 that stand up on triangle board) do not trigger motors or anything
- sensor on triangle board functions and detects when a disc is being placed in the drive (turns on PS3 when beam is interrupted)
- CECHE01 board (broken PS3) on CECHA01 drive (working PS3) acts the same way; doesn't take/eject discs or anything
- CECHA01 board and drive (when attached to broken CECHE01 PS3) works as far as taking/ejecting discs and spins up, so cables and connectors of broken PS3 are fine (obviously won't read them, as not married to this PS3 unit)



Thanks for all the replies guys

Why not just shell out the $40 for a new drive and swap the NAND's. It's likely it is original as you said. If it's not original, tough luck, remarry it and be happy with that.

A quick way of knowing if you have the right logic board is when you put disk in you get the little spinning wheel icon on screen, if not then its wrong board.

Could also be broken board. Also someone reported that the wheel does spin even with a wrong board. I think it depends on models, I haven't noticed mine spin when I used a wrong board.

Go here.. and scroll down to see which BMD fits your model.

look in ps3devwiki

you can install rebug 3.41 and enable QA mode using that CFW. use the BRD less or patch pup to bypass the upgrade stuck issue wen installing FW without a bmd in the system.
You can use MFW to patch your 3.15 to install on your system similarly, once you are in QA mode..
I used the teensy++ to get my system down to 2.30 using patched BRD less PUP's so i could marry the BMD to my system.

sorry the link is fuc ed up. even though my count is 32 posts.. i cant seem to post urls..
but use that google url shortcut i put in albeit without the spaces and you should be good.
