Quoted from cngizbleevng:My right flipper is gradually getting weaker over the course of the last week. It now barely pops the ball up to the multiplier most of the time. Any suggestions as to how to figure out what's wrong?
The soldering under the playfield looks good and the flipper moves smoothly by hand.
Check your EOS and flipper button switch, read this.
