If you've got a blank screen on your psp then you'll have to follow this simple steps to know if you'll need to replace the screen or not.
Step 1. Place it on charge and try switching it on, if it does not power the screen on then move on to step 2.
Step 2. Pull out the battery and put it back in, then switch it on. If it powers the screen back on then you are good to go but if it does not then you could be moving close to a replacement for your psp.
Take the psp to a certified sony repair person and he would fix the screen for you.
