So this has happened before with a psp, but i did the sony refurbish thing. It started slowly and then it throws out all the problems. So when i play my psp sometimes the screen goes dark, in order to get my screen to come back on, i have to switch the power to lock then up a little or else i turn it off. If i reset the settings the volume is on, if i touch the volume it automatically turns down, and when i try to access the internet typing something in, it automatically shuts the keypad screen off. This is very frustrating, id like to know what the cause of this is it's the 2nd time and it makes me really mad.
