My 520-keyboard did the same after 2 years of use.

Cleaning the contacts didn't solve the problem.

Replacing the 40-pin socket for the 6301 processor did solve the
problem.

If You do not dare to un-solder the socket, try to pull out the
processor, plug a gold-plated (expensive) socket in and plug the
processor to that.

The pins of the socket have a greater diameter, so they get more
pressure and better contact; the gold plated socket does not corrode as
much as the tin plated ones do...
