How to Fix Horizontal Lines on Hisense TV Screen

Hisense TV Screen Issues

Common Display Problems

Even the best of gadgets have their hiccups, and Hisense TVs are no exception. Just like any other electronic device, they can face pesky screen problems. You might notice a flickering screen, weird colors, some dead pixels, or those annoying horizontal and vertical lines. Horizontal lines can be a real pain in the neck, messing up your binge-watching nights. Pinning down the exact cause is the first step to getting your beloved TV back on track.

Troubleshooting Horizontal Lines

Seeing lines on your Hisense TV? Could be a bunch of things causing the chaos. It might be a faulty T-Con board acting up, which is the part that keeps your picture timing on point (link to source). Loose cables are another usual suspect; sometimes they love sneaking off-duty inside your TV. Not to mention the dust bunnies that can invade and mess with the connections.

Here’s a quick look at what might be wrong and what you can do:

Cause	Solution
Trouble with T-Con Board	Swap it out or get it fixed
Loose Cables	Give them a good reconnect
Dust Bunnies	Clean that stuff out
Wonky Video Settings	Tinker with settings, especially HDR features

Tweaking those video settings a bit can work wonders. Turning off forced HDR while streaming has smoothed things out for many, especially on the Hisense 4K 75-inch models (link to iFixit Answers).
