This has me perplexed. Ive just burned an entire half a day on it. I own a TCL 55" roku TV. I have it mated with a soundbar and a shieldTV unit. Ive had 0 problems with any of it since day 1. however, a few weeks back I went to watch a netflix HDR show with my wife, and while netflix SAW it was hdr capable, and the tv's HDR tag popped up when i started the video - the image didnt correlate. It was super dark and washed out.
I began troubleshooting. Of course i did the staple hdmi port switch, cable switch, and refresh rate switch on the shield. All resulted in the same. I tested the TV's Netflix app and it displayed dolbyvision content fine, so i knew it had something to do with the HDMI input/shieldtv+rokuTV pairing.
After further troubleshooting, it seems to be an incomplete refresh/handshake, when I click on the video. The screen goes black as it switches from/to HDR from non. Except for when i arrive at HDR, its not right.
The only thing I found that will get it to work properly, is if I use the roku remote to back out to the home screen while the "hdr" video is playing on the shieldtv. If I move to the input square that allows you to preview whats playing, I can actually tell its working as the image is substantially brighter. I re-select the input and go back in to proper HDR. This lasts until I back out of netflix or play a non hdr video, anything that causes it to "refresh" back to hdr mode. It's like the tv is having trouble with changing from standard to HDR.
Anyone seen similar behavior pop up? Any ideas what it could be or how to narrow down the culprit? Trying not to point fingers but im leaning towards the roku tv.
My whole tv screen on my TCL 55inch is washout and I can still hear the movie or whatever it is I’m watching. And the bad part about it is that I don’t have warranty on it . So what I do now. I came home with it like this .it was working fine when I left for the week
Hello @Belinda_79
Thanks for the post.
Have you tried contacting the TV manufacturer to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
