Hi mc1978,
This looks like an LCD issue. Kindly check the system warranty status from the below link and provide the system service tag through a private message if the system is under warranty.
To send the system service tag through a private message, click on my Forum username and then click Start conversation.
You could call the spares team on 1-800-999-3355 (US only) in case if the system is out of warranty. Please let me know if you belong to a different region.
