Mobile devices like the PSP are easy to be dropped and potentially damaged. The PSP parts made to be rugged for active use, but they can break if the device is treated too roughly. Sending it back to the manufacturer will be expensive if the warranty date has passed, but many PSP parts can be removed and replaced even by amateurs. Disassembly instructions can be easily found on the Internet and will show you how to remove commonly broken parts. You can often find PSP parts manufactured in other countries, but wholesale dealers usually offer free shipping so you don't need to worry about paying too.
