I just installed a new lamp driver board on my stern “pinball” machine. On startup instead of the chimes, I get the solenoids firing and it flashes 70. 8 on all the player score displays. If I push credit button it starts a game but won’t kick ball out and if I manually hit any of the scoring features it adds random amounts to the score. Please help.

Absolutely no problems before swap other than the two lights that weren’t working and the one light that was stuck on. Main board has nvram module installed
