Hi, I have a Sony PRS 300, used only 2 days and then blank screen, I check the manual, maybe a battery problem, connect the USB cable and appears the screen Opening Book.
I made a lot of things to fix it, but no one get it.
I bought a PSP wall charger, charge for 20 hours and nothing happens, a red led flashes only few minutes and that's all. In the beginning of the problem I connected to USB charger without sucess, please If you have the same problem, let me know how did you solve it. Regards
