Good evening.

I have been working to sort out a Stern Hot Hand. Currently, the unit is powering up most lights including those in the backbox but not powering up the displays or the game itself. I thought the rectifier board might be partially fried so I put in a Rottendog board but the game is not doing anything different. I have two sets of driver boards but no combination works. All fuses test good.

Any ideas on what might be going on?

Thanks,
Justin

No light on the MPU. TP2 and TP5 both read .019V.

Sorted. Apparently, overcoming stupid is going to continue to be a challenge for me. I missed the "M" reading when testing fuses. The 4A SB fuse on the rectifier board was blown.

All is back and working now. Huzzah.

Thank you for the help.
