Black screen on a onn roku tv that hasnt been dropped

The problem is when the TV is turned off, it will not turn back on.  It would show a black screen with sound.  If I use a flash light to shine on the screen, I would be able to see a very faint home menu.  So avoid turning the TV off if you are able to get the screen to show after resetting.

Now despite some people saying that it's a problem with the backlight, it isn't.  I was able to bring the TV back several times from the death using either the reset button and/or unplugging the power cord.  Sometimes I was lucky and it came back other times I need to try resetting multiple times spanning 5-7 days.  Once the screen has come back on, avoid the following:

1. Never turn off the TV.  I configured the TV to never turn off and just use the screen saver (digital clock).  Optionally, I set the screen saver mode in 5 minutes (15 minutes is the default setting).  I also turn off/uncheck the CEC device sleep mode option as well.  It's for my sound bar that is compatible with the TV.

2. Remove the power button on my Roku remotes so I don't accidentally turn off the TV.  I have three (3) Roku remotes.  I removed the power button on two of them and put one away safely.  I needed to keep one to fix the TV when the black screen problem recurs.

3. Now this is a very special but important one to watch out for if you use Amazon Prime Video on the TV Roku menu.  Do not select/run the new episode original prime videos that are advertised at the top half of the Amazon Prime Video home screen.  As of 09/12/2022, they are the Samaritan (Sylvester Stallone), Lord of the Rings, etc.  I ran these movies and the screen turned to black with sound and it could never come back on without resetting.  Regular movies showing on the bottom half of the screen are ok.  So to be safe, I think, these movies can be watched using a laptop connecting to the TV via HDMI.

Hopefully, by not turning the TV off, I would be able to get more life out of the broken TV.  Not sure how much more electricity it would consume.  TV nowsaday is like a pc.  Turning a pc on/off would shorten it's life.  I hope the same would hold true.

Above all, I think This is more of a software problem and neither Onn nor Roku wants to address it.

    I bought three of the same tv around the same date and mines are doing the same thing. I have tried all of those things also. Mines did not start that until I updated them. I am not sure what to do anymore. I even bought new remotes and they came right on but after a month it started back no showing a picture.

    I’m having issues with mine it will come on updated and I can watch but once I turn off I can’t get it to come back on at all. It very frustrating. It was working fine two days ago turned it off now I can’t get it to come back on at all. Any suggestions cause I can’t afford to keep buying tvs when this one is only a year old.

    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.

    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

    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.

      Return it get your one year warranty again if you can. They go out it seems they be a major problem ONN isn’t addressing. They just say it’s no longer their problem.
