Changed the battery on the wife's F4 last night. After the change, a couple of the lines on the display (on on the seconds part, one on the main time part) aren't working?!

I tried re-fitting it a few times, leaving it 10-15 mins in between with the battery out.

Have I knackered the display somehow?
