Black Screen On Roku Ultra after Update

I updated my Roku Ultra and after that, the Screen Reboots to the dancing Logo and then goes black repeatedly while the white light just flashes intermittently.

I have moved it to other TVs, swapped out the HDMI cables and am using ONLY the original power supply.

Customer Support is no help and I am fed up with this product.

 

HELP!!!

@DougDC 

Thanks for the note. 

We would recommend that you try performing a factory reset on your device.

For more information about how to perform a factory reset, visit our Support page here: How do I factory reset my Roku® streaming device?

Re: Black Screen On Roku Ultra after Update

Same thing, my Roku is blackscreen.  If I reboot, I can see the dancing Roku letters, then it goes right back to blackscreen.  Performing a factory reset using the reset button on the bottom has not helped.  Is there anything else I can do or do I need to return it.

@JackFrappart 

Thanks for the note.

How are you powering the device? Is the device plugged into the TV USB port or is it plugged into the wall with the provided cables and adapter?

Please make sure when trying to perform a factory reset that you press and hold down the reset button for 30 seconds, regardless of what is happening on your screen.

Please keep us posted.


Thanks,
Danny

Re: Black Screen On Roku Ultra after Update

I am having the same issue with the ROKU Ultra. My Samsung Plasma auto switches from 720p to 1080 after bouncing ROKU letters then the screen goes black. There is no way for me to set the TV to default to a certain screen type. Was working fine last night but this morning no good.

I did plug this ROKU Ultra into an older Vizio TV and it worked fine. Seems to be something wrong with ROKU’s auto detect feature.

I performed a factory reset to no avail.

Brand new Roku Ultra - Flashing Black Screen every minute or so on 5 year old Samsung TV.

This is VERY disappointing!  I received my ROKU Ultra box today and connected it to my Samsung UN40H5201AFXZA 40" TV that is capable of 1920x1080.  Previously, I was using the Frontier/Verizon set top box at 1080P resolution and NEVER had a problem.  I am running the latest firmware on the TV.  It is a 2014 model so it is between five and five and a half years old.  The other three TVs in my house are all from about the same time period so my fear is that all of them will experience this same phenomena that makes this "cutting the cord" solution untenable.  Sure, if I cut the cord I might save $100/mo.  However, it would take me at least three years to realize enough savings to justify the initial outlay.  I will bring this up with Roku and Samsung tech support over the next few days and I hope that the solution is a simple one and does not require me to replace TVs as I simply won't do that.  I'll instead return the ROKU Ultra, with the new HDMI cable I got from them, and continue using cable.

Re: Brand new Roku Ultra - Flashing Black Screen every minute or so on 5 year old Samsung TV.

I've got a Roku Ultra 4660x2 and all I get are the bouncing Roku letters then the screens cuts off. I've factory reset and tried multiple cables and even bought a new one and still nothing. My Chromecast Ultra works just fine on this TV

Re: Brand new Roku Ultra - Flashing Black Screen every minute or so on 5 year old Samsung TV.

I have the 4670R, it's only a month old.  Did an update and there were none.  I went into system settings to restart and now like others... i get the dancing ROKU when it first starts up and then nothing... black screen.  Unplugged for 1 minute, didn't help.  Turned TV off and on, didn't help.
