Curious issue in GOTG. Groot's mouth moves on its own during attraction mode. The mouth motor is disabled in the settings. But when I look at the playfield, I can see some of the lighting is also misbehaving.
This game has a really poor design choice when it comes to the board that drives Groot's mouth. It's controlled over SPI bus and it's the last device in a long chain of LED boards. When they develop an electrical issue with the connectors, in addition to less critical lights control issue, the game's main feature gets messed up too. It has been so unreliable that most owners just use software locks instead, like I do too.
So imagine my surprise when after disabling the motor in the software I see it moving like this! I need to figure out which connector is bad and then probably just pull the motor's power cable so this won't happen again.
