hi, i got a japanese version psp, milky white, but now i have problem with it, the reason is this: i drop my psp into a bucket of water before, but after that i dry it up and it still work fine, just a little bit problem with the analog stick, but after sometime the analog stick become fine too, so i assume my psp is back to normal, but someday before, while i play with my psp, it suddenly switch off, and i never get it turn on again! just wondering what happen and can this be fixed?
