Return the tv. RCA makes horrible TVs. I deal with them on a daily basis for work and everyone of them looks awful. Good luck More on reddit.com

Walmart, RCA, $300. I mean how many more signs did you need to avoid that tv? Especially as a patron of this forum? Anyways, cheaper tvs will have trade offs, image may look good but your gonna be lacking on power and processing. And honestly if you are gonna go cheap at least stick to a low end model from the big names, Samsung, LG, Sony. My girlfriend got a 37" 4k samsung from sams club for under $500. Great tv, has no issues with playing back 4k content. However the trade offs are its slower to start, the apps are slow but work, the image is great but has limits to adjustments so the picture will never be perfect. But if you go budget do your homework. Or best bet, be patient and save money for at least a mid tier tv. LG has a great 65" for $700 that looks fantastic, its fast, and all the apps are snappy, only thing its lacking is real HDR. I waited forever until I got my KS8000 and ended up getting that for $1200 right before they went out of stock. More on reddit.com

It looks like a Tcon (timing controller) board issue or a bad flat flex cable/connection to the tcon board to me, as it is mostly only happening vertically on one side of the screen. Tcon boards are usually located near the bottom or top half of the TV in the back and generally have two large flat flex cables that plug into them, one for addressing and driving the left side of the screen and one for the right. If you google "Tcon board", you'll see the two long connectors on one side of the board, and one long LVDS connector on the other side. I would try unplugging these connectors, gently cleaning with them with Isopropyl alcohol / qtip, and try plugging them back in. More on reddit.com
