Just got LIS and am noticing what appear to be problems with the upper magnets not releasing. Right magnet only releases the first ball to the VUK (to launch to spinning disk) during hyperspace multi ball and left magnet used to "stop and drop" balls down to the pop bumpers appears to "hold" balls as well.

Any suggestions on how to troubleshoot?

Does it sound the magnets are staying energized (and I would expect them start causing play field damage ala The Power in TAF if they were)? Or is there some sort of residual magnetism staying in them and/or the balls staying magnetized somehow?

Unsure how to proceed, any suggestions would be appreciated!

Thanks!
