Hi, I scanned a few files that I thought might be useful to solve this problem. I uploaded them in the files section of this forum. I think the problem might be coming from the voicing board but I might be wrong. Like I said, this is a pretty big service manual so you might check in the table of contents and the list of illustrations to see if you need some other files in order to solve the problem. I will scan them and upload them. Nicolas
