For unknown reasons my FT-847 was starting to act strangely last week. I was 
not able to TX on 160 and 80 mtrs. I make a full microprocessor reset on the 
menu item 39 All init and all functions returned to normal. Probably the 
microprocessor became corrupted with time?

You can look also at the mic audio pin on the circuit board. I blow up the 
resistor due to probably to the application of high voltage i never trace where 
this voltage came from?

Hope you will be able to solve your problem.
