looking for help. i'm new to this so forgive me if this has been covered. i have had this motordome pinball machine for like 25 years and it has been sitting for about 15 years unused. when turned on, the lights all come on but thats about it. no led flashes on the board. it has the 6803 board with the leaking battery that was pretty much destroyed so i replaced it with the swemmer mpu board. i checked the test points and tp1 has .04 volts way less than the 5v it should have. and all the other test points are no where near the voltage they should be. i assume since the lights are on and the fact that lots of people have told me its rare for the transformer to go bad that i should replace the power module board next. i have read that the capacitors go bad after about 10 years. i am trying to get this up and running for my kids so i would love any input on this. thanks. also it should be said that i don't have much experience with stuff like this.

i dont have the skills to fix the board myself. i just want to know if replacing the power module is the logical next step. or is there something else i should try first. thanks for responding.
