Hi @MTNester,
Thanks for posting in the Roku Community!
After reading your note, I understand that your Roku Express 4K is continuously blinking blue lights. The blinking blue light might be an indication of an internet connection issue.
Have you tried rebooting your wireless network to see if that resolves the issue you are experiencing?
If this issue is not resolved, please let us know along with any additional information you may have that would be helpful for our team to assist you further. Kindly includes the serial number/device ID of your device by going to Settings > System > About.
Please keep us posted and we'll continue assisting you from there.
Best regards,
Mary
