With all ribbons disconnected other than display one I noticed that the
display stabilised if "digital" fingering of the empty mainboard socket
for the ribbon that goes to the sw board and pair of analogue mx chips.
Reconnecting that ribbon the display still scrolled but tugging on the
fixed end of the ribbon stopped it. Resoldered the ends and display and
overall functioning seems normal, eg up/down bank buttons function,
unlike before. Nothing obviously wrong with solder or the crimp?
terminals to the wires that are also the solder points but something
wrong there. Not PbF but resoldered all 4 such ribbon fixed ends JIC. As
maybe generic Boss problem area they are no-name white "Harwin" 0.1 inch
type connector system for discrete wire ribbons, same crimp? system at
the fixed end (inserted into the housing then soldered to pcb) and
socket end , so standard sockets at one end and solderable thru-housing
and pcb pins at the other. So is it coincidence the other one was
playing up the same way and was genuinly cured by factory reset or same
wiring problem coincidently disappeared for the present on that one? Or
of course some other intermittant problem with this one coincident to
fiddling with one connector, the repairman's dilemma. Repairing (or not)
by divination in effect.

I've now had word back that both units have only been connected analogue
to amps and guitars, no midi or digital connections. Not bought from
same supplier either.

My 6 suffered road abuse. Was dinged and dented but never failed. Just an
FYI. Don't think those problems were endemic to the 6 unless their were
changes made to the 6B.
