Hello,
Finally I found some differences between signatures (Reference vs Suspect).
If you look at the pictures, what do you think, am I right? can I think that U56 is a faulty component?
It is very possible that it is. You will want to look at the other components and see what differences they have. You can send the MDB file to info@huntron.com if you would like us to look at the troublesheet.
Was U56 faulty or not?
