Re: Roku tv screen goes black

Jump to solution

75 inch hisense built in roku. Turned tv on. Clicked youtube app and screen went black. Sound there. Screen dark but seen with flashlight. Unplug, waited, start button and finally reset button. Used light to set back up (reset twice)and still only sound with black screen that can only be seen with flashlight. How can so many of these go out about same time for the same thing? It worked fine up until 30 minutes ago. A 75 inch! 1 and a half years young. Very disappointed. My OS lg tv much better. I have (had) 3 roku tv's (tcl, hisense, hisense) and my lg and hisense is basically done. No more built in roku tvs for me. Any other suggestions on the problem?

This started happening to my Roku brand TV today, model 65R6A5R. It happens when connected to my cable box, not when streaming. When the video switches between the program and a commercial, the picture goes blank but audio continues. It's like the TV's video loses sync due to the change between the program and commercial and it doesn't recover sync. When I turn the TV off and back on, the picture comes back but goes away the next time a commercial comes on. I tried connecting the cable box to a different HDMI input but the same thing happens. The TV is less than a year old; I bought it last May.

we all have the same problem.  Roku needs to make it right.  Won’t. Happen.

I put my TV on the curb and will NEVER buy another Roku TV.   

For THIS many people to have the same issue and they didn’t issue a recall?!??   Bad business.  Very bad business. 
They lost a customer here!

Roku Sharp TV screen is black but still has sound

Jump to solution

My TV recently did this too. Sound but black screen. I tried the flashlight on it and see a very faint picture. It's a 55 inch Hisense. I'm hoping this is an easy fix

Re: Roku tv screen goes black

Jump to solution

I have some more information on this problem which started yesterday. I have always had the brightness setting on my TV set to "Normal", but the night before last I was streaming a movie on Amazon Prime which had rather dim video, so I increased the brightness up to "Brighter". I left the brightness at that level. Today I realized that the brightness level was still at "Brighter" so I reset it back to "Normal" and, lo and behold, the problem went away. This is clearly a bug with the TV. The problem symptom is that the screen sometimes goes blank when the input video switches from the program to a commercial or from one commercial to another; the display comes back after recycling the TV's power.  The TV must be either losing sync and not recovering or, perhaps when a bright commercial suddenly comes on, the TV's video circuitry shuts itself down because it thinks it's being over-driven. As an electrical engineer with a lot of experience designing and troubleshooting video display systems, I think these are the most likely causes. In any event, this is something that Roku should be able to fix with a firmware update. This is happening on a 65 inch Roku Plus TV made by Roku, not TCL, Hisense or anyone else, so Roku owns the problem. This video blanking should not happen regardless of the TV's brightness setting.

Re: Black screen on two out of three TCL TVs

Jump to solution

Two out of three of my Rokus have a black screen at the same time. What is the fix and how to prevent the one that I hardly turn on from going black too? They are all three the TCL Roku.
