Far from a pro here but I have owned 26 pins and 16 were EMs. I have made 4 house calls now and was able to fix all 4 EMs for them. I had to make 2 trips once because there was alot to do and like I said...not a pro so I am not super fast. If anyone needs any EM related help I am willing to at least give it a try. While I have worked on and fixed several things on my own "newer" pins I am definitely not comfortable working on your expensive/delicate boards...lol
