Hisense bad after sales support

really disappointed in Hisense's customer care. I purchased a TV in March 2016 and conveniently in September 2020 when its out of warranty the TV broke down. Hisense isn't even showing interest to fix the TV out of goodwill because I've noticed that this seems to be a common issue for Hisense TVs becausei know other people who also experienced the problem but were lucky to get assistance from hisense. The plays sounds but there is no video. I was so happy with Hisense when I first bought my TV that I even purchased a hisense fridge now I'm scared the fridge also starts giving problems. Hisense please help me.
