Posted: Thu Jan 24, 2013 5:12 pm
Hello
well i have a big problem ..when i swich on my arcade machine with naomi 1 and virtua tennis i have after 1- 2 min i/o jamma board error
i thought it was the tension 5v or 3.3 or 12 v but ok
after i change for new one Capcom I/O Jamma Converter and same problem
so i thought it was the naomi board ( with power supply on it , so i bought a new used one and same problem
after i change the epr rom for all other i have and same problem
after i remove the cable and video board and same problem
after i change to another arcade board and same problem
after i change to others game and i/o board defecting problem appear immediatly
so so i really dont know now
it could be the cable ???? cut signal and appear i/o board error jamma ???? i really think but i tryed with 2 other cable and same problem
i tryed with i/o power supply system ( with power supply computer an ssimple i/o )
so some ideas ..i am to the end of my knowledge ;-0
waiting news from expert naomi boards
thanks
