Hi Jeff.
Has the electronics board been damaged at all previously and this why you require a replacement?
What issue are you experiencing with your 578PRO ActivBoard?
Have you been in touch with Promethean Technical Support directly to see if we can help assist with the warranty? If so, please could you provide the previous case reference number so I could look into this for yourself.
If you haven't been in touch with Promethean regarding this ActivBoard, I would recommend contacting us via phone or filling in the contact form. Please provide the serial number of the ActivBoard when you get in touch.
I have created a case to start assisting with this issue, if you would like to quote 00421372 when you contact us the representative at Promethean will be able to assist.
