Faulty Hisense TV on Sale

I was really excited to own a "55" Smart QD ULED TV (55U6H) on the 24th of May 2023.

Today it's a month old and my set is covered in ink at the top from left to right side of the TV.

Now I'm wondering, is this the reason Hisense has a four year warranty? 🤔

Initialy I wanted to buy a Samsung but somehow I listened to Hisense consultant and made a wrong move buy purchasing this brand😡😡😡.

Only now I see reviews of this product.

I'm really dissatisfied with the brand.
