i upgraded my old streaming stick to a Roku Express 3960RW and the incompatibility started on day one. Please refer to my reply to Mal4romcal for the whats and how it's now fixed!
Hi, my problem was with the Roku Express 3960RW streaming player, don't have a Roku TV. Please refer to my reply to Mal4romcal elsewhere in my post for the description. It seemed to reset itself after 3 days of having to redo the display settings
p.s. I should have been clearer. I have a Roku Express streaming device, not a Roku smart TV. I am having the problem with what the Roku box is sending to my (vintage Pioneer plasma) TV via HDMI.
Have you tried the Roku on another tv? Also try another device on the HDMI port to make sure that the port isn't the issue. If the Roku doesn't work on other TVs either then try to use a different HDMI cord. Try all of these things and let me know how it goes.
Bear in mind that when I press Back on the Roku remote control, the black screen is replaced with the normal YouTube display. So suddenly the HDMI cable and TV input have come to life? Seems unlikely.
Next time the problem occurs I plan to do the following.
The TV has three HDMI inputs, currently used for two Humax PVRs and the Roku device. I shall unplug the HDMI cable from the Roku device, then unplug one of the PVRs and use its HDMI cable to connect the Roku device. On selecting the new input on the TV, so that it is seeing the Roku device, I confidently predict the black screen will reappear.
Watch this space.
My tv when black and a bunch of lines, still has sound. I’ve only had my tv 5 months. Do I get a refund?? Apparently it’s happens to a lot of Rokus and it’s still being sold? That is an issue.
@Nreyes00, who made your TV? If it's TCL, Sharp, Hisense, onn, etc., contact them:

It's Roku's firmware update. Happened to me and I gave up, I then tried using TV somewhere without Internet, only antenna TV. Surprise surprise it worked fine. Brought back to original location without connecting Internet (to Roku operating system at least) and still worked. Bought an external streaming device, and plugged it into HDMI port. Connected only the device to Internet and now I stream just fine through that.
That’s exactly what I did. It’s really a shame that Roku won’t acknowledge this obvious bug and fix it.
