[Kenwood] Faulty TH-77E

[David M0WAM]

Hi,

I'm hoping some-one can shed some light on this:

Today I turned on the TH-77E and there was the usual noise on a vacant
channel (squelch turned down).  After about five minutes when I was doing
other things the noise suddenly stopped.  The display was still on, I tried
another battery, but still the same.  I then found that it's not
transmitting or receiving on either VHF or UHF.  The display, controls, VFO,
lamp etc. seem to be working fine.

So no TX, no RX and no audio.  My first thought are no volts somewhere, but
it would be a real help if someone could suggest where to start.
