Okay, I have an old psp 1k. When I try to turn it on a green light comes up. That's it,. I swaped the power cables, I've tried turning it on with the cables in, and I've even tried taking the battery out and turning it on with the cord in without the battery. I called sony, they said they'll repair it for $90. Thanks, but no. I also have a psp 3k running 6.31 and since it is not hackable I figured that if I get the psp 1k working it'd be a good mod machine. Please help? Thanks.
