My Fujifilm S8000fd is dying!

Today I was taking the camera out, and I noticed weird flickering and odd lines appearing on the screen:


This was taken with ISO 6400 with a 4-second capture to get the worst case scenario. I’m not sure what causes this, but I fear that there is something wrong with the sensor. This doesn’t happen at low ISO values though (ISO 64 is pretty much flawless) so I think its related to sensor ISO:


This was taken at ISO 64 with a very short exposure since there was a lot of light, and it seems to be okay. Hopefully I can still get some more use out of this camera!
