I followed you instructions, which were great by the way, and when I turned the PS3 on and inserted a disc, it would not accept the disc. If I power off the machine and then try to insert the disc half way the console turns itself on but still will not pull in the disc. I bought this drive from eBay as a new item and says it is guaranteed to work and I did swap out the circuit boards. I also rechecked everything to make sure that all of the connections were tight and in as should be but still the drive is not pulling in the disc. ANY suggestions as to what is going on? Thank you
