Remove batteries from the remote. Hold down every single button on the remote for five seconds. Then, replace the batteries. Next, unplug thepowercord from theRoku, wait for five seconds, plug thepowercord back into theRoku, and wait forRokubanner. Mar 7, 2015
Once the banner shows give it a couple minutes and you should get to the screen where it shows cable box.
I didn't change the batteries-only took them out and put back in as indicated.
Would like to 2nd this. Turned my TV on this morning and the screen stayed black. Hit power button again because I thought I didn't turn it on. Could see it powering down in upper right corner. Repeated this several times. Came online and found this forum. Kept reading all the complaints until I came across this post. I work in IT and sometimes we have to discharge (unplug and then hold down power button) computers in order for them to boot up. Figured this was the same issue here. So I unplugged and held power button on remote. Waited 5-10 minutes and then plugged TV back up. Sharp banner came up. Thought I would have to re-setup the TV, but all my settings were in place. Didn't even mess with batteries in remote.
Hello ActtBadd, You lucky dog! I wish this had worked for me, but that being said, I certainly hope that it works for someone else. Thanks for posting and should you hear of anything else that may be of benefit, please take a second to make a post. One never knows if it could be the trick that works for others. Thanks again and stay well!
My Roku TV won’t come on and the screen is going from blue start up to black the red light is blinking,I have up plugged it push reset and still the same my son got this for my Christmas gift in 2019 and now I am being told that I need to buy another TV well no more Onn.Roku TV’s in this house they are no good so don’t give money away because you can’t get any help if you didn’t buy extended warranty.
The issue you are experiencing may be related to a hardware issue. Have you tried contacting Onn support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
