We i have a tv that when yoi turn on the tv the logo and everything looks normal but if we try to get tv going like antenna or connect a dvd player to it. The screen is dark and when changing pic settings like normal and calibrated the screen gives off a dark red tent on the entire screen, but the other pic settings are dark blue color. I cant get the color back to o normal i have reset the tv under factory reset, and done the unplugging tv and holding down the power button for 5 seconds and plug back in. Nothing helps. What should i do??!!
