How to Fix Black Screen on TCL TV?
Black screen on TCL TV is a hardware issue as long as the cable connections are good and everything is fine on the service provider side.
If the TV shows a black screen as soon as you try to access the TV settings, there might be a severe hardware failure. Probably one of the display components among the display panel, T-Con board, LVDS cable, or backlight inverter has gone bad. Please consult this article on how to replace the display components on your TV in such a case.
However, if you are able to access your TV’s menu and settings, we suggest you go through the 8 fixes discussed in this article.
Check Source Device and Connections
You certainly have a source device connected to your TCL TV for streaming. It may either be a set-top box from a cable operator, a gaming console, or a device like Amazon Fire Stick.
Sometimes, there is nothing wrong with your TV, but the issue on those source devices can cause black screens. Please inspect if the source device is correctly turned on and in a working state. You can also unplug and replug those devices to see if it solves the problem.

Moreover, the HDMI cables used to connect those devices to your TV can be faulty as well. So, it would help if you get a replacement HDMI cable and use it to connect those source devices. If you see that your HDMI port is broken, please consult this article on how to fix a broken HDMI port on TV.
