Hi. My left flipper just stopped working peoperly.
When pressing button i can see a little movement.

When grounding the middle lug on coil it fires.
I tried switching left with right optos. In switch test the button works but when moving flipper to top position the eos dont indicate.
I have around 50 v on all coil lugs.

Any suggestions?

Hi. Thanks for yor time.

When switching the optos the result was the same. Also when switching coils the flipper wont fire. The flipper does get energised and moves when pressing button. But only moves a few millimeters. I can feel a bit of resistense when holding button and moving manually. The eos wont register when pushing flipper manually. But when i test continuity with my dmm it works.

My fliptronic board has a few new transistors and u4 and u6 ic is new. And the soldering job is not good.

After some reading i might think the u5 ic is bad.

I havent measured between lugs. And i havent checked q3.

Im probably going for a new fliptronic board, cause i dont like the messed up i have

A new rottendog fliptronics board did it .
