Hi there.
Trying to sort out issues like this can be difficult. There can just be way too many questions and things left out. I think you have not posted all symptoms and problems so things are now going off track.
I would be able to help you over the phone and probably be able to get to the root in a few minutes. I own an electronics repair company and have helped technicians over the phone for years. If you would like I can give you my number.
