Cyclone Williams Cyclone, system 11B: The top segment on the player 2 display unit has gone out (I believe it's the 'a' segment). That's a 7 character, alphanumeric display. It had been working until I did some work on loose display units. The brightness is still good in the unit and all the other segments are working fine, and all the other displays are working fine, so I suspect its one of the ICs. My limited research seems to indicate it could be one of the 4050 or UDN7180 chips. Where I could use some assistance is which chip is for player 2, segment a? My reading of the schematic seems to indicate it's the U2 chip (4050), and if not that, then maybe the U12 (UDN7180). Given the issue is limited to the player 2 display, can anyone offer some guidance on which chip would be the likely culprit?
