[1000mp] Loss of RX in Mark V

[WX5L]

Hello,

I have a FT-1000MP Mark V that I am having intermittent sensitivity on 17
meters. I can temporarily recover the sensitivity by tapping the PTT but it
soon returns to faulty condition.

Reading the posting on this reflector it seems the problem is probably the
relay on the HPF Unit that is in the 17 meter circuit.

I'm looking for some advice on the difficulty to change this tiny relay. Is
it marked on the board which one belongs to each band? 

I would consider myself moderately experienced on small repair work but at
60 years old my eyesight is not what it use to be.

Is it difficult to get to this board.  

Is there someone out there that has done this work that can give me some
advice. 

Does Yaesu provide replacement relays?

Thanks,

Randy
