Thanks. Perfect guide and it worked, only issue could be the temperature and time of the heatgun. I tried on several scrap harddrives before doing it to the PS3 board to verify the right temperature and time- by testing you can check when the chips gets unsoldered. It may be a good suggestion for people that does not have long lasting success with this repair. It may be that you do not get the temperature high enough to get the solder to float underneath the chip. Frank.
