hi all,i have a mace dark age cabinet,but whenever i try to turn it on,nothing appears on screen,nor audio can be heard.i checked the board,and the leds together with the reference manual,and it appears that 3 leds that are near the processor,that are suppsoed to be turned on just for few seconds,than going off or blinking(according to the manual),are on,and again,according to the manual,it means they're in "processor reset" state,which i don't know what it means,nor the manual says what to do in case.any help?
