I have a Data East Star Trek 25th anniversary and the VUK out of the scanner hole is consistently weak. It usually takes 4-5 tries to get it out of the hole, each time resulting in a scanner award which is undeserved. Additionally when in multiball and there are a few balls down there it will almost never kick a ball up.

I've replaced the coil, and the coil sleeve then recently I replaced the entire core+plastic/spring upspring assembly. Any ideas on how to improve this would be greatly appreciated!

Look for cracked soder joints on the PPB and on the cpu boards.
Maybe bad connectors.
As last resort, check the bridge rectifier in the back box.

Shoots out like a bat out of hell now. Resoldering everything in the signal path and replaced the BR.

Now I need to fix the darn thing shooting STDM. Thanks for the help!
