You certainly have a weird one there! It must be a problem in the main board. If you need the part, let me know we can help you on price for the board. One thing you will need to look at is what Tag level the printer has installed. Inside the right door, you will see the toner waste bottle. To the left of the waste bottle, there is a label attached to the frame. This label has many numbers on it, some of which will be marked off. Look to see if #25 has been blacked out. That will determine which version board you need.
