[Yaesu] FT990 Main Frequency Knob stuck

[9A3A@spidernet.com.cy (Ivo Pezer, 5B4ADA/9A3A)]

Hi,
This morining all of a sudden my main frequency knob on
FT990 got stuck. The more I try to turn it the harder it
becomes. Seems to be mechanical problem and I'd like to fix
it before ARRL, so please any comments or hints.
