Hi @beanman56
Not sure if these two links are any good to you but maybe worth a look.

''Note:'' The website linked above is a bit temperamental in that when you click on a link in the page to open a particular repair section, sometimes it will just hang and not open the document and other times it will open the document with no information. When this occurs wait for about 5 seconds and then refresh the page (e.g. press F5 if Win PC) and check if it works. Sometimes you may have to do this 2 or 3 times but it does work!
