Hisense 58" TV nightmare

I have actually run out of words to express my frustrations with my hisense 58" tv. 3/4 repairs later and the TV is still not working properly. Kudos to them for attempting to repair however repairing the same thing 3/4 times should indicate that the whole unit is faulty. Iv asked hisense to replace it even with a second hand tv as long as it works and has a guarantee which landed on deaf ears. I have 3 different tv brands and have had no issues at all with the others. Think twice
