Grundig Satellite 700 with dead FM band
 

Hi all !
My Grundig Satellite 700 has now a dead FM band.
The local oscillator for FM is working, because I can pick it up
quite well on another FM radio,exactly 10.7 megaHertz from the
frequency the radio is tuned.
The radio works reasonably well on AM and Short Wave bands, but
the external antenna input is not working ...
Any help regarding this radio will be most appreciated, as
I have no circuit diagram or workshop manual for this set.
Mail any possible answers to

Thanks
