Have TV Questions? Ask a TV Technician
Hello and thank you for your question. I look forward to assisting you today. Which model of Roku do you have please?
No not necessary at this time. When you get home, turn the TV on to the Roku input, then unplug the Roku from the wall outlet for a minute or so. When you plug it back in, watch the TV and see if anything appears on the screen, even if its only for a brief second or two. Get back to me with what you find please and we can go from there.
She may be able to unplug the power right from the back of the Roku?
What I wanted her to watch for was when she plugged back in and not so much when it was unplugged. I am trying to determine if this might be just a problem with the little power supply/wall cube that plugs into the wall. We really need to try unplugging it from the wall to test it. If she can get to it, check it to see if it feels warm.
That could be the whole problem? Those types of power supplies fail frequently. How old is your Roku?
Well that kind of takes that idea off the table! How do you have the Roku connected to your TV?
If there is a problem with the source, (Roku) you would only see black, or your TV would disable that HDMI port thinking it was not in use. There should not be any snowy picture? Have her try a different port on the TV.
Okay. You can have her pick this up and I can continue with her if she likes?
