Roku TV stuck on black screen please help.
My mom bought a 70" Roku TV after the last one broke. I changed the brightness to "brighter" and the screen flicked off. I've gone through all the tricks online to reset the TV and sometimes it works but now what ever I try to do doesn't work. I'll get a quick flicker of the screen, but that's it. The rest of the TV works fine, it still makes sounds navigating through the menu. Anything else I can do other than a complete reset? I really don't want to take it back to the store to get it repaired. My mom is already angry about me "ing up her TV.
