I purchased a TCL Roku TV from Best Buy in 2016. It worked great for 3 years. I noticed it started getting dimmer and dimmer until it went almost completely black. Unplugging worked for a while but it was never as bright as it was when purchased. Christmas, 2019, my mom bought us a Sharp Roku TV from Best Buy. Also worked great. I loved Roku’s format so I wanted to stick with it. One week ago, I was watching the TV when the screen went out AGAIN. Of course it’s just over a year old so no warranty. There is not a trick or troubleshooting tip I have not tried. The TV is done. The picture will come back on every once in a while but only for an hour or two, then right back off again.
So today, I’m on my way back to the store to purchase yet ANOTHER TV. It will not be a Roku TV. I’m not sure what Roku is doing with their light boards, but this shouldn’t be such a predominant problem. My living room has a regular LG TV purchased in 2011. Still works great, never a problem.
Experienced dark screen (silhouettes of blue and red images) with good audio but only for the Rogers Ignite TV. All Roku apps were perfectly running, no issues. Tried switching HDMI (1 and 2) connections to Rogers box, switched as well the two Rogers boxes, and used HDMI 3 connection using the HDMI cable provided by Rogers Ignite. Still the same issue - having dark screen.
Through all these switching, unplugging of Rogers boxes, etc., tried unplugging the Roku tv from the power outlet and replugged after 5 minutes. And it worked!!!
Rogers technical support told me that sometimes Roku tv needs to be unplugged from the outlet to perform some reboot.
Are you using a Roku player or Roku TV? If you are having an issue with your Roku device screen going black, we recommend unplugging your device for 5-10 minutes then plugging the Roku TV back resolves the issue.
To restart your Roku player, go to Settings > System > System restart. Restart Roku TV : Go to Settings > System > Power > System restart > Restart.
Does this clear up the issue you are seeing? Please keep us posted.
