After I paired my Roku Express 4K remote to my tv, it now only turns on/off my tv but will not power on my Roku. After I use it to turn on the TV, I have to unplug the power cord from the Roku to get it to power up. I tried to find a way to unpair the remote from my TV but haven’t been able to find any steps. I tried disabling my remote but was given a warning that it cannot be disabled. I need help to unpair the remote from my tv. Thank you!
Sorry, you can’t. The Roku does not turn on or off with a remote. It can only turn on when it’s plugged in or when you restart the system, and in case the device is not in use, you can only choose a screensaver.
@Tivoburkee is knowledgeable about remotes of any kind, and may help you in this case.

As was stated, Roku devices don't turn off, but some do go into a "power saving" mode. Try pressing Home on your remote a few times to wake the Roku in case that's what's happening.
Another question — what is the model number of your television set? Find it on either the back of the side of it. I have a Magnavox/Philips 27” CRT TV set with a manufacture date of September 1994, and the model number is printed on a sticker label on the back, where the manufacture date and the serial number are, reading TS2756-C102.

Roku operating system version 10.5 added added a new "Power" item in the "Settings > System" menu for some of the newer Roku devices. At this writing they are currently Ultra LT/Ultra (4801/4800), Express 4K/4K+ (3940/3941), and Streaming Stick 4K/4K+ (3820/3821). The new "Auto power savings" item there will put your Roku device into a low power standby condition after a period of inactivity, such as when your tv has been turned off for a while.
Pressing a Roku control key (like HOME) on your Roku remote (not Power, Volume, or Mute if you have them which act on the TV, not the Roku) should bring the Roku out of standby and back to full operation. Pulling the power for a few seconds to restart the Roku will restore full operation as well.
The power savings are very small and for the hassle it causes, I don't think it's worth having this feature activated. If you disable the options under "Settings > System > Power > Auto power savings" it should prevent your Roku from going into standby in the first place.
