i bought an 80gb ps3 with a broken blu ray drive. it wont accept games or anything. i opened it up and put a game in it and will only eject it out. it also spins but wont read it. im planning on just buying a whole new drive, but do i have to go through the whole remarrying and logic board thing or can i just purchase one on ebay and plug the ribbon and the other cable and get it working again. im looking at one that says it will work with my ps3. any help would be good thanks.
