Anyone younger then say 70 should be well versed in the usage of the internet. It amazes me that people don't do a little searching before they ask questions about various problems. It will stop the posting of opinion and provide an insight to facts. Forms are great for sharing experiences which may pinpoint a failure and determine a diagnostic procedure but stating guesses leads people down a rabbit hole. So lets try to be a little constructive here and share solutions instead of taking a wild guess. The more data points you have the more real the information is.
