My company has a VM40 that ran fine until an eletrical spike. When machine powers up we get PC not ready and slbus error, slbus data is there but scrambled, tried typing data and numbers typed in as small letters. Seams like ladder is partially there not complete, several service companies tell us it could be Micon Board or Seicos board. Any help with this would be appreciated, we are a small shop and need this machine running. Boards seem to be hard to find and expensive.
