I recently bought a ps2 with matrix infinity modchip. For some reason the screen won't stop flickering. I've tried using different cables for it without any luck, and also tried using those cables on a regular ps2 and they seemed to work perfectly. Has it something to do with the modchip? If so, how do I fix it? I've already tried the pal/ntsc switch thing, and it didn't make a difference. The PS2 also boots with this flickering screen even if I don't start a game.
Any help is appreciated.
