I have to troubleshoot a dot matrix on a Stern Playboy. It does not work but there is one dot lit in the middle. The owner replaced the display only to still have the problem. I'm thinking it is in the driver board.
Does anyone have schematics or practical advice on this. I just want to have a good idea before I'm there. I do have the Stern Service Bulletin that covers the testing of U201. Any thoughts would be appreciated.
