How can I repair the inside of the screen/lens?

Recently, I was traveling on a plane, and I had my camera inside my backpack. When I turned on my camera, I noticed that there were several "ink lines" on the screen. However, I realized that the camera is still functional. I just need to have the insides repaired.

I know I have an old camera, but it always worked well for me, and I have some personal sentimental value. I just want to be able to use it again. Please contact me as soon as you can. Thank you very much.
