Hi
Hoping someone can please shed some light on the strange goings on with my Bally AFM. Has been rock solid for 6 months. But in recent weeks the following gremlins have appeared
Problem #1
The right flipper is operating on its own intermittently. Not at full ‘snap’ power as normal, but goes up and down by itself during gameplay intermittently; almost as is it’s getting low power for a split second. Game plays ok, but if the flipper is having a mad moment, it can be annoying when trying to catch/cradle the ball.
This is only happening during gameplay.
Problem #2
The coil that fires the ball up and out of the stroke of luck hole randomly fires during attract mode. Again, this is intermittent. Sometimes it happens once or twice. Last night I caught it doing it half a dozen times in a row then stopped.
It doesn’t fire randomly during gameplay.
I have noticed that both these issues occur after a good hour of the machine being on and played. Could be a coincidence of course, but thought I should mention it.
What I’ve checked so far:
Cleaned both flipper opto boards. I noted one opto is cracked at the base on the right opto board, however in switch test, all 4 opto’s on both boards register.
Ive swapped the opto boards over to see if the problem followed to the left flipper. However, I did this, as soon as I pressed start, the right flipper fired and locked on without me pressing the flipper button! I immediately turned the game off and swapped the opto boards back over. Turned back on and game working again, but gremlins still there.
Any advice on where you think I need to look would be greatly appreciated.
Thank you

after closer inspection of the left flipper opto board, I can see a few cold solder joints! Might explain the flipper issue. Will reflow this tomorrow and see what happens
