Did you ever find a solution because we have identical situations. I tried everything but can't get the screen to come back up. It just flashes the Onn logo and then goes black. No faint picture if a flashlight is shown on it. I've tried everything you mentioned and nothing.
I too lost out on the warranty for the same exact reason. I'm so frustrated because I paid a lot for a TV to stop working just over a year old.
I've tried all the recommended fixes: unplugging, soft reset, hard reset and the button sequence: 5 home button, 1 up button, 2 rewind and 2 fwd. This goes into the reset, but the reset screen only flickers on for a second and is then black again.
Very, very frustrated. I can't afford a new TV.

My tv is experiencing the same thing. Never dropped never moved. One day I pushed the home button to get out of an app. And it black screened I used all the advice to get it back on. Finally came back on but every time I turn it off now it black screens. Sometimes it takes days to get it back on. Now with everything posted online I can not get it back on. Sound fully works buttons on the remote start up the apps. What can I do to get the screen back? #onn #roku
Same thing for mine, it worked for a while now nothing. This is a manufacturer defective and should be recalled and fixed. I would have never bought such a large tv if I would have known of this problem and the lack of customer support on this problem.
@SamRokku70Inch, support for that kind of problem must come from the manufacturer of the TV which isn't Roku.

My onn 70 inch Roku tv will go black with sound. Then I do the unplugging, the resetting, and everything else people recommend. It will last sometimes 4hrs, sometimes 4 min, before going black again. Any suggestions other than return it? I still have a month to go on my warranty
I’ve now tried all of these process. I can’t get it to turn back on. It’s been about a week now since I’ve been able to turn my tv on. ONN just says it’s out of warranty there is nothing they will do. I can hear everything playing any buttons I push I hear the show I accidentally pick 🙂 that’s all.
