i dont know is this will help but i will try
this video might help
also i've never heard of this "yellow light" before. is it like the equalivent of a red ring for the 360?? this may be a new problem, have u tried looking at the manual for the ps3? (lol, i know, its a stupid thing i just said, but i'm just trying to help)
as a side note:
wtf is wrong with the rest of u, stop b----ing about which system is better, i'm so sick and tired of that stupid crap, if its so bad, y dont u go make a system yourself. then we'll let u know if ur's is better or not. this guy (or girl) came asking for help for 1 thing and ur fighting over something else. for those ppl, STFU!!!!
