2010 XF touch screen

[M40ABO]

hi, I'm hoping you all can help me. My touch screen on my 2010 xf has gone blank, I've been advised and tried doing a hard reset on the battery terminals, I've charged the battery. After the first reset the screen worked, but the next day it was blank again, resetting no longer works. Charging the battery made no difference either. I can't help thinking that the screen isn't broken as it worked after the reset. Any advise before I buy and fit another screen?

It could be indicative of a worn out battery. I had it a few times after doing several short journeys and I knew the battery was nearing the end of its life anyway so I stuck a new one in. The issue with the touch screen has not reoccurred since.
