Greeting @Dz3r8y,
Thanks for your first post.
I'm sorry to hear that you're having trouble switching back to the HDMI input on your TV after using your new Roku device. It sounds like an unusual issue, but let's see if we can figure out what's causing it and how to resolve it.
Firstly, I would suggest trying some basic troubleshooting steps to rule out any simple problems. Have you tried turning off both your TV and your Roku device, you can unplug them from the power source, wait for a few minutes, and then turn them back on. Sometimes, a power cycle can reset the devices and fix any glitches.
Also, make sure that the HDMI cable between your TV and your Roku is securely connected at both ends and not damaged or loose. If you have multiple HDMI ports on your TV, you can try switching to a different one and seeing if that works.
Please keep us posted on how it goes.
Regards,
Nimfa
