I sent my F4 off for service 6/5 and Fisher got it 6/8. I was going to email them about the last of this week and see how it was going. When I got home from work today it was waiting for me! The packing slip said they found the problem and fixed it and they also replaced the 11"dd and 8" coils. I have had my F4 for a year and half and it seemed to be losing depth and the ID would no longer lock on unless it was a shallow target. I will put it back together later tonite and try it out tomorrow at lunch. It is too hot right now at about 100 degrees. Nothing like summer in Ga. and it is only starting lol.
