Hi, I just picked up this D&D ... Everything "seems" to be working properly when it is turned on > however, it will not start the game. I have tried dropping 2 quarters in coin slot > makes sound but screen never says 1/2 credit or 1 credit ... and when press START/COIN DOOR button > nothing happens ... also tried setting to FREE PLAY (65 and hit ENTER on Key pad) ... and nothing (BTW > Screen never said FREE PLAY) ... the only thing I have done to game is replaced the broken GROUND STRAP from coin door to cabinet with a thick piece of wire ... Fuses look good but haven't checked them ... Could it be a fuse? or could the START/CREDIT button on coin door be bad (or that diode on that switch got fried?) ... Coin door switch is definitely making contact ... THANKS
