The way I understand it, a lot of the electronic components are magnetic. Everything stored in a computer is stored in pluses and minuses. So, with time the nasty metals and chemicals that are combined to store those pluses and minuses lose their magnetism and their ability to pass the information to the next component.

If you can find someone who can repair a board, they un-solder the component on the board and replace it with a new one. Like I mentioned earlier, some of the more advanced boards are produced in vacuums or other sterile environments that a guy in a shop can't replicate.

Many of the newly designed boards contain the same components that were designed years ago and are still being made. They are just put together in a different way or in a different environment. They are combined with newly designed components to make a new board for a new application. So, the failed component may very well be available, just not the board.

I want everyone to know that I'm repeating what I've been told and do not have any direct knowledge of electronics. I had a lady who worked for me who used to be a technician at Texas Instruments. We discussed the boards in sewing machines and the ability to repair them on several occasions. I'm repeating what I think she said.
