[1000mp] MP just went deaf

[Ron]

I own an FT-1000MP that has had very little use.   I finally got is set
up on the operating desk and started playing  with it  and after about
an hour of listening it went deaf.  I was listening to the  AM
broadcast band  at  7 MHz  when all of  a sudden it started to  drift
around in frequency then finally totally became deaf.  I have lots of
noise and the front controls all work but not signals.   So did a loop
just go out of oscillation and it becomes an alignment issue or did
some part fail ?

I am not a Yaesu fan  but do need to get this thing working. I cannot
afford to have someone work on it so need to fit this myself with this
groups help I hope.

Where do I start ?

Thanks

PS  Sure glad I wasn't going to use this radio this weekend in the
Sweepstakes got my trustly Kenwood TS-850SAT for that but my long term
plan was to make the FT-1000MP the contest radio...but you can't work
them if you can't hear them.  .
