Hey guys, recently i bought an used blue Psp 2001 from an online site in my country (somewhat like ebay), and it works perfectly fine, but! sometimes when I press the O (circle) button a little bit hard, the screen loses brigthness and red vertical lines appears all around the screen, sometimes when I press it a little bit more hard the screen goes somewhat white and then goes back to normal. Also note that sometimes when I shake the console the vertical lines can appear and the screen has 2 dead pixels. What do you guys think? could it be a loose conection on the ribbon cable.. or is the screen just dying on me? Could a screen replacement fix this problem? thx for your time reading this.
