Hello, I'm working on a twilight zone with a strange problem. But let me start off with the first issue it was having. There was a problem with the game resetting if you pushed both flipper on at the same time. I went through and did everything that the pinwiki said to do for a resetting game. I found that the problem was a bad thermistor on the power line coming into the game. I replaced it and the resetting stopped. But there is still another issue. When you turn the machine on, all the inserts flicker (when on), and sometimes an extra ball will kick out if you press both flippers, it also flashes the upper gumball flashers if you push both flippers on a the same time. This all only happens after about one minute, then stops. I re-flowed all connectors and have gone through everything I can possibly think of. I did find that BR1 was bad, so I replaced it along with new caps and it's still having the issues. I have tried everything I can think of and have done everything the pinwiki says to do for a resetting game.

What else could possibly cause this?

Thanks for your help!
