Resetting of a machine is often a 5 volt problem. Recapping of the power supply often helps a reset problem. Reseating of cpu roms will often loose their stored info and go back to factory settings. Batteries and holder should be checked if haven’t been done yet.

i have anew power supply board got it last year ,and what do you mean 5 volt problem

[pinballdaveh]

A 5 volt problem is when the power supply doesn’t put out the correct voltage. About 4.9 to 5.25 is a good range. I checked the online site flipperwinkel, they suggest you test or change the flipper diodes. If the diodes are bad or not soldered properly the surge will be felt in the cpu board, causing resets. They say that other coil diodes being bad could cause problems also. Check out the site for more info.
