Thought I'd share this issue with mine in case it happens to someone else. Got my LED Pro about 10 days ago. Put about 60 games on it and now the front drop target won't stay up on it about 80% of the time. Every once in a while it will stay up but not often. The game will try to raise it typically twice, sometimes four times, and then leave it down. Every once in a while it will try raising it ten or twelve times before giving up.
Every once in a while it'll leave it down and I'll hit the second target and it'll reset them (or start trying again). Seems like a mechanical problem but will continue to try and sort it out.
