DX4330 - LCD failure

After several years of good service my father's Kodak DX4330 camera's LCD
view finder now just displays a horizontal line above which it is dark and
below light. It is not possible to get any menus or review or frame photos
using the LCD screen - permanently appears as described above.

The camera continues to be able to take photos, and these can be transferred
to PC via the Easyshare software and docking station.

Only recent change was that a new PC has been used to transfer the photos
and this needed a more recent version of Easyshare software - I am assuming
it is a coincident that this was done on the same day the problem appeared.

Any suggestions?
