Flakey player 2 score display

The score display for player 2 is kind of flakey and is often missing a digit (although it's not always the same one that's missing; I've seen at least the thousands, hundreds, and tens digits affected, although not at the same time). Hitting the backbox can display the missing digits occasionally.

Also, the ten thousands digit on player 3 flickers between showing the correct value and something else.
