Sony PSone LCD screen demystified

This screen has a high saturation with composite video. With just the volume and brightness (backlight) buttons, there's little you can do.
But after opening, I discovered several things.
The chip that responsible for the OSD has some hidden menu's.
Settings are stored into a 2402 serial eeprom.
This chip reads settings from eeprom and continuously sends the commands to the AN2526.
More info soon ;P
