  OK, I'll say 110M is a typo, then. :)

  As regards the problem, are the resistors OK? R4308, R4295, R4297?  On
my P600 I had a resistor go all funny on me: tired of its life at 26.7K,
it decided to become a 43K resistor.  It was really stable, too, not
intermittent or otherwise flaky..just...not the marked value.  Replaced it
and all was fine.  Maybe one of those resistors above is broken or
otherwise doing interesting things?
