Have an odd issue on Nitro Groundshaker with the displays. When you turn the game on they are nice and bright and within a few seconds they fade until they go off. Just like there was a dimmer on them. Reboot the game, it does the same. Any idea where to start looking? Thanks. The game plays fine after the displays go blank

Hi voltage cap been replaced?

If you have a voltmeter, measure the voltage at test point (TP) 2 on the solenoid driver board. This is in the high voltage section, so be very careful. It should measure around 175 volts. Your TP2 may be much lower and that is why the displays are fading off.

I tried a new Alltek solenoid driver board, and the same issue happens.

Problem solved. Was the Alltek ultimate MPU. Swapped it out with another and all good now. First time having trouble with an Alltek.
