Typically with a partial LCD failure as you describe, it is a result of damage. Has the phone been dropped, hit, crushed? Or exposed to water, heat, or direct sunlight for an extended period of time?
Photos of the phone as Jerry requested would certainly help.
Hi Mary Jo,
Can you add a picture of what your screen looks like?
Adding images to an existing question
Also, has anything happened with the phone lately that could be related, such as being dropped, getting wet, a new update, etc.?
