i have a ps2 slim with matrix modchip. it used to read burned ps2 disc. few days ago, i switch on my ps2 from standby mode and it led me to the matrix configuration menu. i tried restarting the device without changing anything. from that point of time, my ps2 will show me the red screen with the message "please insert a playstation or playstation 2 format disc". i tried starting the device from stand-by mode but it gives me a black screen, the device will only work when i press the reset button again (but still unable to read the disc). i tried going back to the configuration menu, but i'm unfamiliar with the settings. can anyone give me some advice? thanks.
