I purchased this NIB Deadpool pro about 9 months ago, and just recently the left flipper started to get "stuck' in the UP position (see pic). Basically, when pushing the left flipper and removing my finger from button, the flipper stays in that position and takes more than 5 seconds to come down, sometimes it doesn't come down at all.
I tried to clean around it (on playfield), but that didn't make a shit of difference.
Any idea what the problem might be? Is it just a matter of greasing up the gears under the playfield?
