well i purchased new wei-ya 15a psu tried adjusting 5v etc and still same. i dont know whats wrong with it, maybe it needs -5v? or mysterious extra +5v like rev1 boards? as other boards are all working i assume its not about ampere. also as its rev2 board it should boot all games right?
according to
wiki
''correctly powered boards will display a blue screen with white text as the board and game boot up. If not powered properly, only a blue screen will be displayed''
i can see blue screen and stuck on sequence1, what the hell is going on here? i started to think its faulty. any help would be appreciated.
EDIT: i put rev1 io chip (big one) to rev2 and it boots fine but picture was too noisy, then i inspected the board and found one of the big 1000uf 16v cap near to power connector is bent very bad and replaced it. i dont know if it make any difference but it still cannot pass seq1. maybe the board damaged during shipping and i powered it like that and so it made permanent damage to something else? like io chip itself?
