My EOS switches were both pretty well cashed so I swapped them both for brand new ones. Now everytime I hit the flipper the playfield flash/flicker. It was never like that.

If I hold the ball in the right flipper for a bit, I can actually see distortion in the video monitor.

Any ideas of what this could be? Game plays fine otherwise.

Could old coils that still seem to work fine be the cause?

Thanks!
