Why buy a TV if you will spend a week without it

Buying a HiSense smart TV has been a terrible decision. The TV only worked well for 6 months from the time of purchase (Nov 2018), after that it only showed colourful lines on the screen with no picture although the sound is on. When you send it to their service centre, they inform you that you have to wait for a week for the repairs. I have never had this problems with the other brands I have used before. If you see a HiSense on sale with a long warranty just consider that you might actually spend some time with no TV in your house.
