Okay guys I'm a tech with a computer store in my local town. Been having an issue with a PS3 Fat Original CECHK01. At first the blu ray drive wouldn't accept discs at all so I opened up the drive and repaired that issue. Then I came across the issue that the disc is not recognizing any discs that I insert. Not bluray games or dvds, ps2 discs, nothing. I've already replaced the laser and that didn't work. So I've replaced the entire blu ray drive and switched out the PCI board from the old drive to the new one. SAME PROBLEM!!!!! I'm at a wits end at what this could be. The only other conclusion I'm likely to come to is that the flex ribbon cable is bad but if anyone has any advice or has had a similiar issue please share some insight so I can get this repair underway.
