Quoted from AwesomeSauc3:I'm having an issue with my Premium where balls aren't registering when they are getting locked in the tower. They make it up to the top just fine, but I don't get the typical video clip or any indication that the ball has been locked. After a bit the ball dislodging sequence (I'm certain that isn't the correct term I just don't know what else to call it) fires and the tower eventually comes down, sending the locked ball SDTM. It did this sporadically for some time but now it's doing it every time. I'm still relatively new to fixing problems on my machines and I'm wondering if someone has seen this issue before and could point me in the right direction. I tried searching around and it seems like there were code issues with this early on that are solved now, but to answer the question, the code is fully up to date, I just updated a few days ago. If this isn't the right board for this please let me know. Any help is much appreciated!
Sounds like the opto at the exit of the VUK might not be registering, then the machine goes into ball search to find where the ball went. To figure out what might be going wrong I’d start by taking the glass off and going into switch test in the menu. Pull out the interlock switch and use you finger or something to block the opto at the VUK exit to make sure that opto is working. If it is working, then get the building into the lock position and roll a ball through the entrance. See if switch test registers the opto when the ball kicks out of the VUK.
