I agree that's the more likely cause of the line and a screen change is the only practical answer in that case. Worth trying removing the ribbon and clean the contacts before reseating though as dasilvarsa suggested in any case, but a dirty or misaligned contact is most unlikely to result in such a symptom. Screens for 14xx are cheap anyway, [Only registered and activated users can see links. ] and seeing you're in Honkers you'll probably get one at 'Mate's Rates'.
