Martin,
I would try giving each of the TMP cables a slight twist.
Secondly, I would remove and reseat the front panel board.
No guarantee that will correct it, but it is a good starting point.

'Crafters,
i have a 7 year old K3 #28xx causing me a headache. I built this (and
other K3s) myself and modified it quite often, so am fairly familiar
with it's innards.
The issue is a dead RX ( no signals on any band, just noise from spkr)
and no power out on any band ( display shows 0.0 Watts) after - say 30
minutes - of just running in rx . When i hit the case with my hand -
like a slap - rx comes back to life and power out works again. I
suspect something has come loose causing a slack joint. Something that
is involved in RX AND TX.
So where should i check? Probably the synth boards?
