Welcome to the Roku Community and thanks for reaching us.
We'd like to gather more information about the issue you're running into. Is there a light showing on your device? How are you powering the device? Is it plugged into the TV USB port, or is it plugged into the wall outlet with the provided cables? In addition, have you tried using another HDMI port on your TV as well as trying your device on another TV to see if you are seeing the same issue with no signal? In addition, can you please specify the exact steps you are taking to reproduce this issue so we can investigate further?
Please keep us posted and we'll continue assisting you from there.

Streaming stick 4K S/N S08Y423KLSDP
I've been using the stick a couple of weeks w/o problems. all of a sudden today, I get the no signal floating all over the screen. I've unplugged the Roku and plugged back, still no signal. Help.
@sandi1141, that message is coming from your TV. Make sure you have the correct input selected. Unplug the power from the Roku and plug it back in. You should see a light on the Roku when you connect the power.
I have tried 2 TV’s and two cables and still no signal.

Let us know if there's any difference after.
All the best,
I tried all I put sources on both TV’s and you can tell when you have the proper input as it gives you the message no signal.
the USB adapter is the original only a couple months old. I did try another outlet with the same result.
Appreciate the prompt response.
I have passed along your information and concern to our Support team. I'd recommend keeping an eye on your email since they'll be reaching out to you from there.
Thank you for your patience and understanding.
All the best,
