Apple Ipod Touch 5th Generation 16gb Player

I just charged and reset this old ipod I bought new many years ago. It works fine but has annoying gray bars across the top of the screen (see pictures). I reset the ipod and the bars are still there. I don't know how to fix and am not going to investigate. It works fine despite the screen glitch. There is a small dent on the back. Other than that just normal wear and tear. Glass has minor surface scratches from wear and tear but no major cracks or anything that would affect use. I don't need the ipod so will sell for parts or repair (because of the gray bars issue). I'll pay shipping within US. Please no returns. Just the ipod is included-I don't have the original packaging. It works just be aware it has the gray repeating squares toward the top of the screen as seen in the pictures.  Thanks.
