everytime i turn my mp4 it turns white

i think is because of the firmware ,i must have updated to the wrong firmware


anyone knows wich firmware is the best for this mp4 (sweex vidi 4gb mp470)
( i donīt know the BOARD ID of my mp4)
this below is the inovix 5500, i think

this firmware is the same as my mp4 (because when i turn on my mp4 it looks exacty the same as the inovix )
