Mine started after 400 plays. Took the playfield down to clean, wax, install some triton rubber and the red witch mod. Ordered some 3/4" Mylar squares from triton and put one down next to the factory Mylar under the wire drop. Then just trim with an exacto blade. They did not get the factory Mylar downfield enough. Also put Mylar at the magnets, out hole and where the balls roll off of the castle playfield.
