Well, a few months ago I sold a premod (SCPH-39004 with Magic 3.1 Final Red). The buyer had problems reading PES3. Since he was familiar with the laser lens problem on PSx he put the PS2 in Vertical position. Then the game loaded in 20%... Then he put the PS2 upside down, guess what.... 100%. So he decided to open the PS2 and adjust the laser. He turned the "nob" 1/4, after that no problem with booting......
