Troubleshooting a ball that gets stuck in the subway under the playfield, on my ST:TNG.
I find it difficult to know where exactly the ball gets stuck - this is since when I am raising the playfield to locate where the ball is, the ball is naturally changing location in the subway due to the pf incline, making it hard to tell where it actually was stuck.
Any one with tips on how to best troubleshoot this kind of stuff? Filming under the playfield perhaps with a cellular?
I am considering of heating or cooling a ball and then using my thermal camera to easier locate it (filming under the playfield or something like that).
How do u guys do?
