T21P backlight not working after F/W update - donb - 11-07-2019 02:29 PM

I recently updated the firmware on several T21P E2 phones. The original version was 52.84.0.95, the new is 53.84.0.95. It was applied through the installed 3CX software UI.
The display backlights no longer come on. Looking at the phones UI directly, the option for setting "Backlight Time" seems to have disappeared (see attached screenshots).
Has a bug been introduced, and will it be fixed soon ?
Thanks,
Don

Apologies - the phones are T19P E2s, which have no backlight.
