I have the same problem. Have tried restarting TV and Roku stick. Sometimes that fixes the issue for a brief period, but then the dark image issue (sometimes in bands and sections of the screen, sometimes the entire screen) recurs. DVD player to the TV seems to work fine, so I think it is the Roku. I would also love some advice on this beyond the basics of restart/reboot.
@Losaltos@ggaabe Thanks for the notes. It's possible that there could be an issue with the HDMI port affecting the display picture, a power issue, etc. There are a few things to try here to see if this helps:
- Try connecting you Roku device to a different HDMI port on the TV, and then playing content again.
- (If applicable) Try using a different/new HDMI cable to connect your device to your TV. You might also try cleaning the HDMI port used to connect the device with canned air to remove dust or dirt. Worn out, dirty, or damaged/bent cables, or dirty/dusty HDMI ports may cause unexpected behavior.
- If your device is connected to your TV for power via a USB port (Streaming Stick models), try plugging it into power using the included wall adapter.
- If your device is connected to a power strip or other power splitter, try connecting it directly to a wall outlet to see if this helps clear up the issue.
Keep us posted from there if you need further help.
Yes, I bought mine in 2016 and it's just becoming an issue now. It's usually when I turn it off (on accident) then go to turn it right back on again. I don't know what to do about it except shutting off again for a few minutes, then turning on. It usually goes back to normal screen after a couple tries. I doubt there's a fix for it.
Usually turning off and on helps. The last time (maybe two days ago?), it didn't. I ended up just unplugging it from the wall. That worked, but I don't think the TV is long for this world. How long are these lower end TVs supposed to last anyway?
