Raya vertical en mi dell inspiron 5000

Hi, I have an inspiron 5570, the service tag is for a few weeks now there have been some vertical stripes on my screen, one gray and one green or blue, I bought this computer in May 2018. I connected it to an exterior monitor but none of the stripes are reflected, and is present in any app you open. The line started as one and a second line appeared a few days later. Does the accidental damage service cover this problem? or which warranty service can I buy? taking into account that the guarantee I had expired a few days ago. Here are some pictures of how the screen looks https://ibb.co/dcJW3Jp Thank you very much I hope you can help me.
