Had the same problem on two of my ST50 instruments last year. Raymarine tech support recommended turning up the brightness on the instruments, saying it might burn off the condensation (it didn't).
The depth died about two months later and the wind speed was starting to go. I ended up upgrading over the winter. YMMV.
