I took a closer look at the specs for your TV and it is only capable of 720p (progressive scan), however, it appears to support 1080i (interlace). It's possible that somehow the TVs internal reporting of it's capabilities may be causing some confusion for your Roku device. I'll pass your report along to my team to take a closer look, and follow up with you via private message for any additional details that we may need. 

 

Thanks,

Tanner

I'm having the same issue with my Roku Premiere+ and my LG Smart TV. I've tried different HDMI cables, ports, a different TV, hard reset, but nothing works. I plug in my Roku to power, it shows the "bouncing" Roku screen, then flickers black, then No Signal, then black, over and over again. The light on the Roku itself stays on.

If it's doing that after all those steps, then it most likely is defective. Roku has a pretty good warranty, so hopefully @RokuTannerD or @RokuDanny-R will get back to you for more details.

@NickBuol  No updates as of yet. Just in case, have you contacted your TV manufacturer to see if they have any further support or troubleshooting options available? 

@kparedes  What is the specific TV brand and model that your device is connected to? In Settings>Display type, what option do you currently have selected? 

 

Thanks,

Tanner

Tanner - thanks for reaching out. It seems to have resolved itself for now. I turned it on this evening with no issues.

Vizio offers no support of this model, and no firmware update exists from what I could find.

The TV works with all over devices via HDMI.  Dish satellite (what we are trying to get rid of with Roku devices for streaming), a Sony Blu-Ray player, and I even tried an XBox One S.  They all work perfectly.  It is just the new Roku Express (2019 version in my case) that doesn't work right.
