My Sports Cardio watch has white lines across it and I can no longer read the display.

I have never worn it in water, dropped it or mistreated it. One day it had white lines across its face and they have got worse. I m am ow at the point I can't even read the time.
Try a factory reset but it is likely a bad display. If it is under warranty contact Support, otherwise it is time for a new watch from a different brand (TT Sports went out of business 18 months ago so do not buy another TT).

Happened with me too. it starts with while&black lines and as time passes, it starts spreading. My warranty was over and I couldn't find somebody to repair it. So, I had to buy a new one.
