Picked up a GBA SP at a car boot today for £5 which seemed pretty good but dam thing seems to have a problem with the screen >_>. The SP turns on, backlight comes on and you can hear the logo noise and game come on, but there are no graphics on the screen. I'm guessing it could be a loose connector or something? So I wondered if anyone had any ideas as to what it could be before I rush out and buy a small enough triwing screwdriver to open it up. Thanks.
