   I have two 21 inch Belinea monitors which sometimes do silly things when
cold, especially if they have not been switched on for a while. In this case
the degauss circuits tend to drop in and out until they warm up.
   The degauss circuit on an ordinary TV relies on a pair of temperature
sensitive resistors, the one in series with the degauss coil goes high
resistance while the one in series with the rest of the circuit goes low
resistance as they warm up at switch on.
   The Belinea degauss circuit is relay switched every time the monitor
comes out of standby, but gets over-enthusiastic when cold.
