Adjust the optics and it may play right.

Are you drinking a beer?
The optics have to disengage for the pull handle to lock. 

Sixcard is likely correct here. Thank you for posting the video, it's very helpful.

It's not "free playing" as you're calling it, but it's detecting the door as opening, then closing, and re-spinning the reels back to their last position. If you look closely on those so-called free spins that happen with no music, the machine just re-spins the reels back to the same outcome of the previous paid spin.

Your door optics are likely loose or not aligned very well, and the physical movement of the handle is just enough on occasion to cause the machine to momentarily think that the door was opened, and then immediately closed.

On newer GAME (SP) chips, those re-spins would stop on reverse order -- right to left -- to make it even more clear that it's just the machine resetting itself to the last outcome, but regardless, that's what's happening here.

thank you, I now understand the reason clearly now. 

Apologies to sixpack.

Wow, that's amazing! I've had my machine for years and never gotten close. Thank you for sharing this.

Count the number of red blinks. It will repeat that number over and over.

Oh ok, good.  Yes, here's a schematic for the motherboard.
