TZ error message says ball popper opto stuck, clock broken and flippers stopped working. All these issues happened at the same time. Had a good look around and nothing popped out at me. Any suggestions where to look for the issue or what the problem could be.

Thanks LTG can you be more specific about those recommendations, I am not so good at fixing pins but will give it my best effort.

Ok I tested all the test points and got no reading on TP5, ???

Any idea what fuse to look for? How to test for bad BR?

Thanks LTG, I spent a bit of time last night checking fuses and finally found one that was blown. Just need to get a new one and see if it fixes the issues.

Changed the blown fuse and the only thing that changed was the lights were on the clock. still having no flippers, broken clock and stuck opto. How do I check the BR and what number BR should I be checking, and how do you test the BR? Reloaded the gumball machine and it said to check the auto popper.

I will check, thanks

no voltage at TP5 and fuse was good

Ok I got the board out and tested 5 BR's

Any advice is appreciated. The board is all original and really thinking I might just get a new one with all the improved components.

Any Idea what components or what BR is related to TP 5?

Well I put the board back in last night after checking almost every wire I could. Ensured that there were no loose wires in any of the connectors, pushed them in the connector with a very small screw driver. Many of them pushed in a little bit. Also noticed that the wire 1 going into J101 pushed in quite a bit and the plastic connector had signs of over heating on that wire. Powered up TZ and no errors!!! Back in action, thanks for the advice guys.
