ok, heres the story. I gave my PSP to a guy at the computer swap meet (like a sunday market for computers) and I bricked or semi-bricked my PSP and asked if he could unbrick it and put a mod chip in it to prevent this from happenong again. So he said "i'll take it back to the shop and see if it can be recovered for u" then he said "it'll cost another 160$(ausie currency) to give u a new motherboard if its dead" so what i did was leave him my phone number and all that and he'll give me a call if its recoverable. now what i'm sceptical about is how he might cheat me out of 160$. So i wanna scare him a little by my knowledge. So what i wanna no is how u can tell if a motherboard is dead or not so i can tell.
