I just bought the Onn Roku TV and plugged it in. The screen has been completely dim since turning it on for the very first time. I cannot see anything on the screen without holding a flashlight directly to the screen. The audio works. I have unplugged and tried the code sequence on the remote. Zero luck!
External Roku box. All apps have issue. Restart several times to fix.
Should be dubbed "gray screen of death."
When playing Teen Titans Go on Hulu for my kid last night, for example, the Roku menu works fine. Hulu menu works fine. Push play- audio works fine. All that shows up on the screen is the Cartoon Network logo. But I can see the Options menu clearly over top. Strangest thing!
My kid says that if he Restarts it and then leaves it on the StartUp screen for 10 minutes before clicking anything, that usually fixes it for him... for a couple of nights....
worked for me. I went to the menu (*) then picture mode. Arrow right to “movie” mode and it went back to normal. I don’t know how or if that setting was changed. I have a Roku tv 65 inch, no stick, no cable. Thank God!
I had a similar problem with my Sanyo 65" Roku T.V.
Home screen and preview for Prime Video displays fine, but when you choose to watch something screen goes very dark and purplish.
Followed advice here and changed the settings by accessing menu by pressing the * button on remote while in full screen mode and changing setting from "vivid" to "movie" mode and that seemed to fix it for now, I don't know how long it will last for. All other modes except "movie" mode have the same issue.
