Vizio d50u-d1 - flickering horizontal lines + duplication

Hello everyone! I’m wondering if anyone could help me with this problem. As the title says I’m experiencing some annoying flickering horizontal lines at the very bottom of my TV. These lines also seem to occasionally copy the image from the very top of the screen too. I know that horizontal lines are typically a panel issue but I haven’t seen all that much about the secondary issue with the lines copying the top of the screen elsewhere. I tried replacing the t-con to no avail so I decided to come here to see if anyone has some insight into what I could possibly do to solve the issue.

I have links to some pictures and videos of the issue here:

Thanks for looking and I look forward to any advice I can get!
