Hey guys, I was want to help those guys who are still facing the black screen issue on their vizio smart tv because last week my brother also encounter this type of issue on his Vizio (Model Number - E500i-b1) tv . His tv kept on crashing and turning off. He told me that whenever he tried to turn it on, the tv shows startup screen and then turn back to off. So when he couldn’t fix this out by himself he called me up, I searched on web and after sometime I got the right page to fix this issue and we follow all the steps as mentioned there, some of steps weren’t useful but we managed to fix the issue by resetting our vizio tv. You can also try resetting your tv to fix your issue and if resetting the doesn’t help you at all then I will leave their for you guys [link|https://droidtheory.com/vizio-tv-keeps-turning-off-fix/|here]
