We are happy to help if you send us a picture of the board and include a note on the version of firmware. Send the information to firstname.lastname@example.org. The method to determine the version of firmware can vary by machine model. The instructions will be included in a well-written owner’s manual.
If you do not include all of the above information, we will not be able to make a recommendation.
If information is absent, it would be best to hire a local service professional to assist.
