No LSB or CW RX


 

Hi
I have a FT-301D from new.
Lately sometime I use it the LSB setting is dead in RX and TX on all bands
USB is ok AM is ok.
I also think CW is dead in RX but seems ok in TX.
Then another day it works ok.
Where should I start looking?
I cleaned all the plug-in boards and switches.
Thanks
