Hi
My LW3 has developed an intermittent flipper fault where one of them stays up when I release the button. It doesn't happen every time & tapping the button again brings it down. I've played with the glass off, and when it happens, it feels like something is pushing back when I try to push it down, so I reckon it's an electrical problem rather than mechanical. I have found this https://pinside.com/pinball/forum/topic/data-east-left-flipper-sticking which suggests it could be a dodgy diode. Is there any way to test the diode in situ? I'd expect not as there is the alternative connection across the ends through the coil.
Is there anything else I should be testing to work out what's wrong?
