Alright, I lost my charger a month ago. I bought a new charger from drugmart, it is a variable charger with multiple heads on it. I plugged it into my psp, turned it to 4.5v (PSP is 5v) and the PSP wont turn on. It is getting power, the 2 metal tabs under the power adapter plug are getting electricity to them, meaning the PSP has power. No lights turn on Any ideas?
