guys,i'm pretty new around here, and i got a problem with my psp. so here goes.

basically when i plug it in to charge, it doesnt charge. the orange light doesnt light up. its happened for a few months already, so what i did was just charge it via USB. but recently my girlfriend used until battery totally kong. so i'm stuck. can't charge.

i suspect its the charging port on the psp itself, but i can't be sure. so what i wanna ask is, what is the problem with my psp actually? read a few forums, they said it could be :
1)battery
2)charger
3)charging port.

if it was the charging port, apparently i'm fcked. :S any help guys?

i see i see.. if it really is the charging port, where can/should i send it for repairs?
