probably a burnt coil , you can check resistance across each one of them to find the short
when you first press the test button, the manual says "all outputs tested" https://www.ipdb.org/files/887/Stern_1980_Flight_2000_Manual.pdf
2'nd press is a lamp test/
3rd press displays (only)
4'th press solenoids (only)
5'th press switches
I think you can isolate what's resetting the MPU by quicker button presses.
when I first got mine a tech told me to replace both big capacitors on the solenoid driver board as their rated life is only about 10 years. one of them is for the displays(high voltage section). http://techniek.flipperwinkel.nl/ballyss/rep/index3.htm#hv

Quoted from Lovef2k:Oh, to answer your question about the MPU LED, yes it will go dim after the initial 7 flashes. Are the voltage LED's lit after boot. This may sound trivial but did you connect the ground strap from the cabinet to the ground screw on the bottom center of the backbox? Also does your line cord have a proper ground plug?
I was wondering about that as well about the ground strap.
setting up the ultimate MPU, go through the bookkeeping functions, (button inside the coin door) then press the reset button on the ultimate MPU board to clear that field.
it could be erroneous data in your credit/match display
