Long story short
My buddy got his STLE,
We installed a the following mods.
- Pinbits Protectors
- MEZLE Light up Drop Target (then removed)
- MEZLE light up explosion plastic
- Cliffy Protectors
- Light up Flipper Button kit
At first it was hard to tell when, but I think last night when we were playing after replacing a bad opto, I think we narrowed it down to when the shaker goes off, the flippers jitter for a brief millisecond, usually not enough to effect gameplay and I don't think it happens all the time.
Now I did also notice when we were originally troubleshooting the opto error 2 weeks ago that occasionally we would see EOS errors for the flippers, then it would disappear.
Any ideas? We checked the spacing of the flipper buttons and it "looks" ok (not 100% sure though)
