I just bought my 50in Onn Roku tv from Walmart. I set it up last night and it worked fine for about ten minutes, then the screen went black and when I hit the power button to turn it back on, it'll just flash for a quick second and then go black again. I've done all the troubleshooting that the internet has to offer.
Sounds like equipment failure. Take it back to Walmart and exchange it for one that works.
Onn is Walmart's private label. They are responsible for supporting it.
