I replace all 3 boards no luck.  Going to changing out ribbons and cables see if that works.

I saw this on-line and it worked for me. 

Remove batteries from the remote. Hold down every single button on the remote for five seconds. Then, replace the batteries. Next, unplug the power cord from the Roku, wait for five seconds, plug the power cord back into the Roku, and wait for Roku banner. 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.

Hopefully this post helps someone else.

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!

Thanks for the post.

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. 

You can reach them here: http://onntvsupport.com/#product_support-2 or at 1-844-334-2355.


Thanks,
Danny
