PS3 problems

[youngWilliam14]

so i just bought a 60gb backwards compatible ps3 off ebay, knowing that it wouldn't read blue ray disks ($180 used vs $400 new, not to mention i can play ps2 games still)

i've been messing around with all the settings, and i took it apart to clean the lens. i know that my problem is the hardware, but is it the drive itself or the control board attached to the drive? the ps3 recognizes that there is a disc in the drive, but will not load the ps3 games or blue ray movies (dvd and ps2 games work just fine--now i need to be pried away from .hack//!)

and no, i do not want to send it in. i am an EET, and i'm not paying sony $150 to do this for me
