I show you how fix black screen issue on the TCL 30 SE Smartphone (should also be similar to TCL 30, TCL 30 XL, TCL 30+, TCL 306, TCL 305, TCL 30 V, TCL 30E) Turn off the TV. Remove the power cable from the wall socket. Wait for 5-10 minutes, let it cool down. Replug cables tightly and switch on the TV. You may notice that after doing this your screen will be stable and you won’t experience any flickering if the issue persists due to any internal settings conflict. It takes about 5 minutes for the Home screen to show up. Each time after that, powering on the TV seems to take 5 minutes more each time to get past the blank home screen. I tried changing the default input to my cable, trying to bypass the home screen at startup. It went to the cable input, I could hear everything, but still had a black screen. Discussion. I removed all of them in mine but I lost power off function on remote and it would be very tedious to discovery which package is responsible for that. I used ADB App Control to disable these TCL bloatwares: com.tcl.assistant. com.tcl.autopair. com.tcl.bi. com.tcl.copydatatotv. com.tcl.esticker. com.tcl.factory.view. .
