Tips for fixing an old Tektronix Oscilloscope?

trying to fix an old tektronix oscilloscope. It seems like the lcd panel burnt out with time but most of the buttons seem to work fine. Before I rip the thing open and have a look inside, any tips?

Hope to be able to write a blog post about this if I succeed. 

Any input is welcome. Thanks a lot!
