Left flipper on last action hero seemed to be losing power during multiball and was fluttering a bit and then stopped working altogether. Upon closer examination it seems that the low power works as it will stay up when I hit the button and lift it up, but won't go up on it's own. All fuses on the flipper board test out ok. If the flipper seems to be working on low power, is it safe to assume that the problem is with the flipper board? I'm going to try to work on it this weekend, but if anyone has any suggestions of where to look for a problem, it would be greatly appreciated.
