If the cab tv monitors fail on the 92 stock, do the drivers just adopt the guard position or take it out of service. Just see a driver basically monitoring opening and closing the doors by standing looking out the edge of the cab door.

Depends - there's two types of platform category on the tube for use when the monitors fail/mirrors become defective. Cat A (easy to remember as A for assistance) and Cat B (which I remember as 'be alright').......Cat A is normally a curved platform where the driver can't see the entire train length from the cab, or it's deemed their view is obstructed by some other means. In this case you can only depart with the assistance and supervision of station staff so the entire train length can be seen.
Cat B requires no assistance (typically a straight platform free of obstructions) so the driver doing the job 'guards style' as you describe can be used.

There are two general reasons for failure of the cab monitors:
1) The monitor itself is broken and would therefore need to be fixed
2) The signal for the monitor that supplies the CCTV footage of the station platform is broken - usually if this happens the station crew will board the cab of a train out of peak hours, have it stop and then quickly repair it IIRC.
With the older 1972 and 1973 stock, cameras/ mirrors are supplied at the end of the platform for the driver to refer to in order to close the doors.

Alex is completely correct in describing the procedure (I use A for assistance B for by myself) also there is the occasions where a camera is knocked out of alignment and that can normally only be fixed in engineering hours as the cameras could be overhanging the platform edge or too close to edge to be realigned correctly without endangering maintenance staff
