Easy: disconnect the two leads from the main battery, touch the two ends of the leads together for a few seconds, reconnect. You will have to reset the window switches (this is in your owner's manual). But is your battery at full charge?

Thank you! Yes, battery at full charge. I let the car sit for awhile and double locked it....when I went back, the screen had returned to normal function. Being that this is the first time this has occurred in driving the car for a year and a half, it's possible that this is a symptom of things to come. I will keep your instructions on file for possible future occurrences:-) Thank you all for taking the time to help me out!! Happy Hollidays.

Your car is still under warranty, so take it back and they should replce the unit.
If it were me, I would remove the head unit, and I bet it's the ribbon cable and very fine pitch connector that connects the PCB to the screen has a partial connection.
Just a wiggle first would most probably suffice, if not delve deeper.
Dealers will just chuck the old unit in the skip I guess...cheaper than fault finding these days!

I am curious as to the method of touching the leads together? May I ask why that is necessary? Honestly I have never heard of this before with a battery reset?

Disconnecting the battery and touching the leads together discharges any current remaining in modules (capacitors) and in theory resets, the screen in this case. Jaguar recommends this on a few of their TSB's. If it doesn't work, no harm done. For those in Europe, you might want to save your radio code so you can re-enter it if needed. No code required here in the U.S.
