My player 4 display does not light up at all. When I switch my ribbon cable from player 3 to 4(on the board) it does not light up player 4 display. I also only partially light up player 3 when I swap them. But it might b cause the cable is under stress due to it being a bit further of a length? I also swapped the entire cable from 3 to 4. Display 4 still does not light. I am goin to order a new glass but I was not sure why I was not getting a full display when I swapped 3 and 4 on the board only? Is that cause I'm stressing the ribbon cable?

What I'm meaning about the "not gettin the full display " is its not full characters, goes in and out. Thats when I switch the output from the display board to connector 4 feeding the display glass player 3. But I have to stress the cable for it to reach. Was wondering if that was a possible cause for the incomplete display?

Oops misread ur post. So I think I have board problems(display)? And my player 4 display also?
