HISENSE TV

I HAVE BOUGHT A HISENSE SMART TV LAST YEAR. 1 MONTH AGO THERE WAS A BLANK SCREEN ON THE TV. WITH LONG STRUGGLE THEY FINALLY CAME OUT TO COLLECT THE TV PROMISING THAT IT WILL BE BACK IN 2 DAYS. ITS BEEN A WEEK NOW AND NOW TV. EMPTY PROMISES. BEGINNING OF THE YEAR I BOUGHT 3 HISENSE TV'S. THE ONE IN THE MAIN BEDROON GAVE A BLUE SCREEN AFTER 2 WEEKS, RETURNING IT AND GOT A NEW TV. 8 MONTHS LATER THE NEW TV IS GIVING THE SAME PROBLEM BUT ONLY A BLUE BACKLIGHT AND NOTHING ELSE. THIS IS BY FAR THE WORST BRAND. I WILL NEVER EVER BUY A HISENSE EVER AGAIN.
