My camera recently started displaying lines on captured images along with some discoloration (you don't see the lines or any discoloration when simply looking through the lens). There was no distinctive action that occurred prior to this issue (didn't drop it or impact it in any way). The camera had been used the previous day and stored overnight in a hotel safe. The next day this started happening and has persisted through a factory reset (so pretty sure it has nothing to do with settings). I have also tested to make sure it had nothing to do with the memory card by removing it and saving directly to internal memory. The lens has also been cleaned and the issue persists.
Is this a sensor issue? If so, can that be replaced on these cameras? If not, any thoughts on what the issue could be or any further steps I can take to narrow down the problem?
Here is a sample image:
