20 gb ps3 blu ray issue.

**CarvinDC125** · 04-30-2011,02:32 PM

Yes I know blu ray issues are all over the forum. well I believe my issues is a little unique. Im not sure if im in the right place but here is the issue.
Well ive been restoring an old 20gb ps3. Im compTIA certified to work on computers so I know a fair amount of whats going on. Well when I got the ps3 it wouldnt even boot. I got it to boot and discovered it had a bad blu ray and replaced it. I kept the original pcb board because they can not be swaped. Well heres the problem the blu ray wont acccept any disc. As soon as a disc touched it the blue light blinks a few times but the disc doesnt get sucked in. So I took the blu ray back, got another one and still have the same problem. So does anyone know what the issue could be? I believe its down to one or two problems at this point either a bad pcb board or the ribbon cable (which looks kinda rough) to the mother board to the blu ray could be bad. Anyone out there got any sugesstions?

baught ps3 that doesnt boot for project.
fixed boot problem discoverd blu ray was bad.
Blu ray wont except discs.
Swaped three blu rays still have same issue
Replaced HDD with 250 gb brand new one.
Could it be a bad ribbon cable from the board to the blu ray?
could it be bad pcb logic board?
What does "rebuilding the database do?
**edit** I have a ribbon cable on its way in the mail.

Remarry the drive.

**CarvinDC125** · 04-30-2011,03:42 PM

would someone be so kind as to send me the .self files I need in order to get into and out of factory service mode to remarry the drive? I believe I have the files already to perform the remarry, all but the 2.30 pup file that is. I need that file too. lastly the system has 3.41 firmware this leads me to believe its been sitting around untouched for sometime.
I believe there is a small chance that one of the persons that owned this machine before me may have ignorently swaped the pcb board or somehow the data became corrupt in the board.

i came across a ps3 that did exactly what you're describing and it ended up being the motherboard. regardless of the bluray control board or bluray drive mechanics, it should always take in a disc. a non-married bluray control board just wont read any data. the chances of you trying 3 different bluray drives all exhibiting the same failure is unlikely. the fault is on the motherboard, specifically, the portion that is designed to communicate with the bluray control board

I work on a lot of ps3s, and I can say that this issue can be caused by the laser not being able to go all the way down.

It sounds like you bought it from someone who had worked on it before. Occasionally if the laser gets changed, the white clip that attaches to it will get caught at a point close to the spindle motor making it not go all the way down.

The drive works in a sequence. There is a little switch next to the spindle motor for the laser to hit. If the laser can't hit this switch, the drive's intake mechanism won't kick in. You can usually just force the laser down to free it and allow it to hit the switch, but sometimes you need to take it out and reseat it.

Can't say for sure that's what it is, but I've seen it on multiple occasions where lasers have been swapped or moved by hand, especially when people first start working on the ps3.

for the most part, yes, you are right. but the OP stated that the little blue led turns on when a disc is attempted to be inserted. that tells me the laser's caddy is set proper and has nothing to do with the position of the laser on the caddy. if the laser wasnt set properly, then upon disc insertion the gears would make horrible grinding sounds in an attempt to set the disc.

aw man I hope the motherboard is ok. The Tech that sold me the two blu ray drives tested the drives as well. He told me that is the logic board is fried or gets hit with ESD it will cause the blu ray to not function.

interestingly enough, the ps3 is HIGHLY sensitive to ESD, more so than your "average" piece of electronics. i remember one time i changed out a hard drive in a 60gb ps3 and a tiny-tiony-TINY piece of metal from the hdd caddy screws screwing into the hdd came off and got sucked into the fan which then blew it onto the bottom side of the motherboard... all i heard was a "snap", but it still powered on. the ps3 would no longer take in discs, but showed the blue led whenever i tried to insert it. i've since used that exact bluray drive WITH the same bluray control card in another ps3 that i re-married it to... works like a charm! the 60gb eventually went back to sony on their trade-in program for a slim....

Its more than likely the motor driver chip on the bluray daughter board.

They sell them on ebay

@ Carvin125
You've checked the sensor right? It fits into the tiniest of the plugs that goes into the control board on the far left side. There are only 2 wires coming off of it. Red and black I believe. If the connector is damaged not to mention the wires or sensor itself that could be your problem. Not probable considering that the blue light comes on but it shouldn't be ruled out until checked over. Hope that helped. Good luck
