PS3 not spinning discs

    Hello.

    Ive searched these forums and scoured the Internet for answers for my problem. Ive tried a bunch of solutions other people managed to solve their similar problems with, but to no avail. Now I come here seeking help.

    I have an old PS3 CECHG04 giving me problems; more specifically it doesn't seem to spin any discs anymore. I replaced this PS3s laser about a year ago and after that it worked perfectly. It was recently I discovered that it doesn't seem to want to read discs anymore. I realized this about a week ago and at that time I hadn't used it for disc games for several months.

    After disassembling the blu-ray reader I noticed that while the laser moves, the discs aren't being spun. A blue light is being displayed, that from what I understand means that the PS3 is recognizing that a disc is inserted and the loading symbol is also visible in the top-right corner at the XMB.

    As an experiment I tried to insert my old laser assembly with the defective lens, that I replaced a year ago. The PS3 couldn't read the discs of course, but it could spin them fine.

    After that I dismantled this old assembly and put its disc spinning device(no idea what its called) into my newer laser assembly. I tried to attach an image of this device, but I couldn't as apparently new users aren't permitted to post links.

    I had no luck replacing the new laser assembly's disc spinning device with the one I confirmed to be working.

    So now Ive come here and created a thread of my own and I hope someone can offer some help. Ill gladly accept any suggestions or ideas as Ive ran out of them myself.

    Some questions:

    -Could it have something to do with the laser itself? I thought about this, but it seemed unlikely since the discs aren't spinning, but they spin fine using my old and busted laser.

    -Could it be purely mechanical? That some plastic parts aren't aligned right or something? If so perhaps someone more knowledgeable could tell me what to look for.

    Thank you for reading my thread. It I have mistakenly placed it in the wrong subforum I apologize and ask for the benevolent mods to move it.




    TL/DR:

    -Replaced old and broken laser assembly with a new one
    -PS3 reads disc fine for half a year
    -Recently it stops spinning the discs
    -Laser still appears to be able to move
    -Replace the spinning device on the laser assembly one I confirmed to work
    -Discs still not being spun by the PS3
    What do?

    Thank you for your reply. Perhaps I should have tried to type it out more clearly.

    I did replace the original laser assembly in the PS3 with a new one(the same laser model) about a year ago. This new laser worked fine after the replacement. I didnt use my PS3 very frequently and just recently I noticed that it doesnt spin the discs anymore.

    When inserting a disc now the laser moves very slightly as if its trying to read the disc, but while it does this the disc is still and is not spinning.

    I tried to insert my old laser assembly which I replaced a year ago. This one actually spins the disc, but of course it cant read it because the actual laser is broken.

    This is what made me question if my new laser was actually broken or not.

    Could the problem still be that the actual laser is broken? I'd like to know before I shell out for yet another laser.

    its most likely the mechanic thing that spins the disc is broken.my paint work on that pic isnt the best but you get the idea.

    2 other mechanic things that could be an issues.either side of the laser.

    I tried to replace that one with one I had confirmed to be working, but it still didnt spin the discs. Ill give it another try though and report back. Thanks for the suggestion.

    An update:

    I think I've tried every combination of spare parts and it does not seem to work. My old laser can read DVDs fine, but not games. My new drive can't seem to read anything anymore and I guess it can spin discs fine, it just won't do it if it can't read the disc.

    From this I can only conclude that I have a second dead laser on my hands and have to get yet another replacement.

    I have ordered a new laser of model KEM-400AAA and I will report back when I've received it.

    I ended up getting a new lens and it works fine and discs are being spun by the PS3. Contrary to what I first believed the spindle motor works fine and it seemed to be a case of yet another busted lens. At first I was under the impression that discs had to be spinning before the laser would activate and attempt to read the disc, so that's what confused me. So for anyone who encounter the same problem of the PS3 not spinning the discs I can only suggest that you replace the lens or the entire laser assembly. Like I said I only got myself a new lens and it works fine together with the old spindle motor.

    Thanks to the people who replied and came with suggestions. As I mentioned my PS3 now works fine and I sure hope this third lens won't break down on me like the two before it.

    Hello! I have the same issue and was just wondering if buying a new drive fixes the problem or is the issue to do with something else?

    I'd like to save time and brain damage by swapping out the whole drive, but don't wish to buy one if it doesn't fix the problem!

    Any help would be great. ;-)

    I have a similar problem. I took a working laser out of a functional drive and put it in another. Disc would insert, but not spin. So I moved the laser back to the original drive and now it won't spin or work either.

    Now I have two drives that do the exact same thing.

    It might be extremely bad luck, but surely in that short time the laser wouldn't have died. I've triple checked that all the cables are plugged in too. I'm stumped

    Did anyone find a resolution to this yet. I have a fat PS3 that won't spin up a disk and I have tried many LASERS / drives / ribbon cables with no joy at all.

    I can load & unload the disk but I never get any LASER output at all. The LASER also tracks down the pole when moved up but that is it.

    I am now 100% positive it is not the LASER or drive mechanics or ribbon cable / connectors.

    I am not sure about the drives PCB though. If I put another wrong PCB for a different PS3 on the drive I still get the same results. Does anyone know if using a wrong / mismatched PCB will ordinarily still allow the disk to spin and the LASER to function even though it will not permit playback?

    If the above answer to my question is yes then the fault has to lie within the console main-board somewhere. I am half convinced this is a uncommon GPU BGA symptom so I might just do a re-flow anyway.

    Solved!

    Turned out to be the BD7956FS motor controller I.C located on the drive P.C.B.
