Roku Ultra No Signal

I’ve had my Roku Ultra 4K for two years now connected to a Samsung TV via HDMI. In the midst of viewing something the TV suddenly said No Signal.

I unplugged the Roku and it worked again until the next day when the same issue occurred. Since then I keep getting No Signal. Even though the white light is on, the Roku doesn’t do anything when I press the remote buttons or the reset button.

I’ve tried different ports, different HDMI cables, new batteries in the remote. It seems like a product defect. Roku support has no advice other than to replace it. My worry is that if it is a hardware failure then I don’t really want to replace the unit only to have the same issue again. This product really should last more than two years!

Has anyone else experienced this and have any other ideas? Is this possibly repairable??

Re: Roku Ultra No Signal

First thing I'd try is a new power supply.. the power supply may be under-powering your Roku.. it night appear as though it's working because of the light on the Roku, but the PS could still be dying. Not bad to have a spare, if you get a new PS and discover a new solution to your problem..
Yeah, I got some Rokus.

I should have mentioned I also tried a new power supply and plugged the Roku into various different outlets!

Re: Roku Ultra No Signal

While no authority, "No signal" generally refers to Internet connection. If you're using WiFi I'd be looking into the router rather than the Roku. Personally I use a powerline wired network since it's faster and more reliable than WiFi. Hope that helps

"No signal" is usually a message coming from the TV, telling the user there's no HDMI signal from a device to the TV.

Re: Roku Ultra No Signal

Right it’s defintiely not a WiFi message. It’s the tv telling me to check the connection to the Roku.

I’ve really tried everything. Since it worked once when I unplugged and plugged the Roku in again, I suspect it’s a hardware failure. What is disappointing is that I’ve seen a few other posts about this so it seems Roku has frequent problems with hardware. And no solution. Probably both worth buying a replacement!
