TCL Roku tv turns on with logo for a fraction of sec, then black out
Hello, I have Model 55S405 TCL Roku TV. When I turn it on it flashes roku tcl logo for a fraction of sec and then screen blacks out. I unplugged tv for 15 mins and overnight , I tried to reset it by pushing reset button and I tried reset from roku remote using “home button 4 times, up arrow 1 time, rewind 2 times and forward 2 times” but nothing worked.
please let me know if there any other way to fix it
