1. Check the power source: Make sure the power cable is securely plugged into the TV and wall outlet. Try unplugging the TV for a few minutes and then plugging it back in.
2. Check the remote control batteries: Ensure the batteries in the remote are not dead and still working correctly. Replace them if necessary.

However, here are some basic tips for troubleshooting your TCL Roku TV black screen issue:

You are waiting to enjoy your evening show, but it is still loading and seems to be stuck on the red screen. Exactly, it stuck on the booting loop.
Although this is not a common issue, it often disturbs many users. However, outdated TV firmware is the main culprit for this issue.
Still, hopefully, you can easily fix this issue either by factory resetting the TV or by updating the firmware via USB.
Here are some methods to get your TCL TV out of the red screen.
1. Power Cycle: Unplug your TV from the power source and wait at least 2 minutes before plugging it back in. In the meantime, press and hold the power button for 30 seconds. (Power button, not the reset button)
2. Factory reset: If a power reboot didn’t help, factory reset your TV. Refer to this article to learn how to factory reset your TCL TV step-by-step.
