sometimes I switch the game on and find all the displays are off, the ball in play display has some light in the lower part of the digits the other four are completely dark. I tested the voltages as described in pinrepair and all is good, adjusted all the connectors and nothing happens. removed cpu board and cleaned all sockets reflow headers etc. but I still get this problem, sometimes works fine, sometimes theya re black, sometimes ball in play display gives a dim-unstable 00-00 so I switch it on again and they don't work. then sometimes the suddenly reappear...I think it's an input problem because the voltage is there. any suggestion would be very appreciated.
