My sony camera lights up the photo so much it is turning white

Hi i have a Sony cyber shot DSC-S40 and it was working great but suddenly one day it started to appear vertical white lines.It started to light up the photo so much that After a few days the whole picture was white but you could still see the photo.This was happening only when i was outside in the sun .I put everything to auto and did a factory reset but it did not do anything.I also tried every setting and every mode but it didn't do anything.IF you know how it can be fixed please respond.
