Same fat PS3...works perfect. Dust, clean and take care of your stuff, use conditioned A/C, make sure house is grounded properly for electric using 8' rod or grid. A lot of people don't know or realize when electronics dies suddenly it's often caused by older A/C specs from old lines to poor groundings. Eventually all those various factors can cripple some electronics but depends on many other factors as well including how good the components are.
Then again your BR player may have died from being poorly designed, defective or low quality parts too. But having a conditioned, well grounded and surge protected A/C in your house does really help electronics last longer. It's just expensive to have a whole house redone like that so most people never do until they get serious electrical issues. It's worth it though, even if you have to do it yourself.
