I had this happen to my '90 100 TQ. Tapping on the dash and starting
again made it disappear, only to come back the next day.
I pulled the instrument cluster (lots of connectors!) and opened it up
in the back. The back panel has a lot of logic that is connected to
the display and the various instrument through a couple of connectors,
and it seems that the pins in this connector may suffer from
corrosion. When I assembled it again it worked ok and has done so
