What happens when a circuit board (motherboard?) "goes bad" or fails?

Are you asking the symptoms of a failing motherboard? In my case, a 1985ish Elna, it started sewing slower and slower. Then sometimes it would quit altogether. It also started loosing features, like always ending with the needle up. I would try again after letting the machine "rest", and it would stitch for a bit. Now it doesn't start at all.
Or, are you asking if it is reparable. In my case, no. I've asked 4 different repairmen, and received the same answer. One suggested sending it to a place in either North or South Carolina, but that seems pretty expensive when there is no guarantee that a repair would be successful.

Mother boards change over time. Newer, faster, smaller components become available, so they are incorporated in the new boards in the new machines. Making the old models of boards is not profitable, as there is not much demand for older models. So, they quit making them.
Some of the older boards can be repaired by electronics technicians. The newer boards are not repairable, as they are produced in vacuums or some other technique that is not available to repair technicians.
If you would like to find someone who can repair a board, call an independent computer repair shop. They might be able to help you find someone who can repair the board if it's an older board.
This is the way I understand it. I'm not an expert in computer board repair.
By the way, you cannot find a new mother board for an Apple Imac anymore, either. It's all a matter of time. If it was a fairly new sewing machine, you could get a new board for it.

The dealer told me when my Pfaff motherboard died, I’d have to buy a new machine, because they don’t make them anymore. So when I saw a good deal on a floor model, I bought it (from another source). I’m hoping the motherboard on the old machine holds up a bit longer.

not always. an older computer has a lot of parts that won't meld with a new motherboard. ask me how i know ..
