Anyway, it has been laying around useless for 3/4 a year, so i decided to finally fix it.
Step 1: The parts/tools
-PSP with a broken screen
-A new screen
-A sturdy philips screwdriver
-Air compressor/canned air
Step 2: Tear down
Locate the 5 screws, two on each side, and one in the center.
Now firmly grip your psp, the screws are very tightly screwed in, if you do not apply enough pressure, you can strip the screw.
As you remove the screws, stick them to your magnet
Step 3: Removing buttons at the bottom
With your flat head, pry the little clips holding the buttons in place.
Leave the button bar connected to the motherboard.
Step 4: Extracting the Screen
You'll need to gently pry the screen out
Once that has been accomplished, flip the screen out towards you.
You need to undo the ribbon cable clamps.
The best way to do this is to use your trusty flathead, CAREFULLY open the clamps.
Step 5: Place your New screen into position
Try not to get any finger prints on the new screen.
Connect the ribbon cables to the clamps, insert and close them.
Press the screen into place.
After you pop the screen back, try turning on your psp, if the screen light up, congrats!
-check the connection to the lcd
-you got shipped a broken screen
-your motherboard is broken (sorry i wasted your time and money :(
Step 6: Put the Button bar back in it's place
Do not scratch the screen.
Step 7: Clean the screen
Get your air compressor/canned air, blow all the lint from the toilet paper off the screen.
