Huh? Do you mean your panel? That shouldn’t affect anything. You could have shot caps in ac/dc conversion or bad bridge rectifier(s). Just need to measure voltage at coils.

Mushroomed plungers, dirty coil sleeves, mechs physically dragging on something .. these all can cause weaker flippers or up/out kicks.

I always rebuild flippers when I get a used game out of habit. Good starting point as part of shop out, along with new rubbers and a deep clean.

Auto launch could be binding on something or striking something, causing it to lose power. For example, on my sopranos it occasionally hits part of the trough switch which results in about 1/2 power.
