Glad to hear that this helped you.
Exercise all those switches vigorously. My 485 took quite some time to become fully functional. I cleaned and used DEOXIT on the thing about 3 or 4 different times before the trace came fully back as it should be. Make sure to use a cleaner that does not leave residue or attract dust.
There are a lot of these switches on TEK scopes and they all suffer from the same malady. Clean everyone that you can find on your 2215.
I find dirty switches and contacts are the number one cause of scope "failures".
Good Luck with your scope.
