pal u have a possible EROM issue, which might be an older version like R3A011
in which case you will have to upgrade it to avoid getting WSOD in the future
check it by accessing service menu >*<<*<* (joystick right,star,left,left,star,left,star)
then go to SERVICE INFO ---then SOFTWARE INFO
it will say EROM: R3A011 or R3A016
