Re: Tv goes black but sound is onn
Mine just started to do this last night. I have tried every trick that this community has to offer. A friend that was having the same issue said that the back light and LED Display are probably burned out. The company only offers a 1 year limited warranty but I've had the set just under 2 years. Now I have to go buy a new TV.

Re: Tv goes black but sound is onn
Same here. I've unplugged it, still dark, I've reset it, still dark, I've done the home (5x) up (1x) rewind (2x) and fast forward (2x) and nothing worked. I called Roku twice and we went through it all again. Then called Hisense who redirected me back to Roku 55". (Mine is Roku not Onn btw) but it seems that this is happening quite often and right shortly after the warranty ends. Smh I hope you get it figured out before having to fork out more funds for a new one.

Re: Onn Roku 70' TV Black Screen, what to do?
A family member bought this for christmas 2022 for a baby's room with one yr warranty. Literally less than a month after the warranty expires the tv goes black. Only used maybe 1 or 2 times a month. I talked to ONN customer service. 1. Couldnt understand a single thing she was saying. 2. Did all the resets and troubleshooting 3. Told me the warranty expired 20 days ago and i am s*** out of luck. Never ever buy an ONN tv is all i can say. Mine lasted 1 yr and 24 days and was hardly ever turned on. Piece of junk

Re: Onn Roku 70' TV Black Screen, what to do?
You can also add me to the black screen list. I purchased my 70 in tv only 2 years ago. I turn it on and got nothing but a red blinking light. I contacted them and they told me there is nothing they can do since my warranty is up. And told me to contact a tv repair person. We all need to come together and start a class action suit!!!

Re: Onn Roku 70' TV Black Screen, what to do?
Hello! @Tinaanddewey200,
We're thrilled to have you join us here in the Roku Community!
- Is this the first time you have experienced this issue?
- Do you have any other device/s connected to your TV?
- Is there a specific input that's not showing?
- Are all cables firmly plugged in?
- Is your TV able to exit "wake up" mode?
Troubleshooting:
- Check the power cord/outlet to ensure the device is getting power.
- Checked the input that you are trying to watch?
- Checked the video cables to ensure they are firmly connected.
- Unplug and replug your TV from the wall outlet.
- If the problem persists, do a factory reset on the TV. Located on the back or bottom of your device, the physical Reset button is either tactile or a pinhole design that requires a straightened paper clip. Once you locate the Reset button and your Roku device is powered on, press and hold the button firmly for about 10 seconds. When the factory reset is complete, an indicator light or status LED will blink rapidly on most Roku devices.
Please keep us posted on what you find out and we will be happy to continue assisting you further. We look forward to hearing back from you.
Thanks,
Arjiemar

Re: Onn Roku 70' TV Black Screen, what to do?
Yes it’s the first time this has happened.And no there is no cables connected to it. It’s just a black screen with no sound. Just a red blinking light. I have tried unplugging it and I checked the power cord and I did the reset button and still nothing. It was working fine. I cut it off and went to bed got up the next morning cut it on and got nothing. It’s really frustrating because the tv is only two years old.

Re: Onn Roku 70' TV Black Screen, what to do?
I did get in touch with them and they said I’m out of luck since my warranty is up. Which is because the tv is only 2 years old. I have other tvs in my house that is almost 8 years old and is still working just fine.

Re: Onn Roku 70' TV Black Screen, what to do?
I had the same issue, I did all the things that were suggested and still had the issue. I finally factory reset the audio and picture settings and it didn't do that again. Once I changed the picture settings for gaming it turned black within a minute. I reset the picture setting and haven't had that happen.
I hope this helps you out too.
08/17/2024 UPDATE: I started having the black screen again and I did the whole factory reset on the t.v. and still happened I did figure out that it would only happen on the HDR mode so I set the picture brightness to darker and it's been staying on. Fingers cross that I don't have the issue later.
