In regard to the 16062021 playfield code.
Found out that its not a production date but that its the refers to design made 16062021. At that date a design change was made (some minor artwork change I think) and thats what the date stands for. So, all playfields made by the design of 16062021 will carry that mark. See it as a version number.
There is (on most of the playfields) also a timestamp of production. Its however at the backend of the playfield on which you screw the backboard. See attached picture. Not very easy thus to get to but its interesting info to get for sure. Otherwise we will have to go from manufacturing date of the TBL itself. For those who wanna do this, unscrew the backboard (think it are 4 or 5 screws) while playfield is pulled forward resting on its servicerails and make a picture with the selfiecam of your phone and sent it to [email protected] incl your TBL serialno. Thanks
For the rest discussion has ofcourse started to decide best way forward. To be contd asap.
