[ICOM] IC-775DSP MAIN UNIT

[Paul Playford]

The flourscent power supply smoked on the MAIN UNIT in my IC-775DSP.

So I purchased a new circuit board from Icom.

But now I cannot control the SUB VFO.

The original board was a B4291E, and the replacement board is marked B4291F.

The E board does control the SUB VFO (no lights though) but no joy with the 
F board (this is the second F board, same problem).

I have sent an email to Icom but no response yet.

Anyone been down this route?
