Yes the text are in japanese...cant help you out though.
Have you got the picture of the Intec PSONE screen? Im getting an impression that the LCD panel can take in RGB signals without an additional controller? Everything is built in on the panel?
The official Sony PSONE screen have this rounded mainboard and it make the screen awkward to install in a small space...the mainboard cant realy be separated from the screen.
Please post some pics
