Most of the time, the issue is largely related to the power modules, and using an alternative supply usually solves the problem. In some rare cases, the firmware becomes corrupted and needs to be reinstalled. This situation is very common in newer versions where a heavy Android OS is installed on the TV.
Common Scenarios
Turning off when using a specific application: Occasionally, the TV may become unresponsive while running a specific app like Netflix. This will result in an automatic shutdown of the TV and subsequent failure to power on, leaving the screen blank or black. Changing the Picture Brightness to a higher setting, such as Brighter, has been observed to trigger this issue in certain cases. Flickering on the screen: There are instances in which a momentary flicker occurs when attempting to turn on the TV. Surprisingly, this problem has been reported even with newly purchased TCL TVs. The majority of TCL TV models have been associated with this issue. Additionally, in certain instances, the TV’s audio functions properly, but no video is displayed on the screen. At times, the power-on light is enabled, but the TV shows no display.
Troubleshooting Prerequisites
Check if the TV responds when you press the remote’s Home button. Remove the Ethernet cable from the TV (if present) and check if the TV can be powered on.
How to Fix a TCL TV That is Not Turning on
We will first cover the most common scenarios encountered in this situation and move on to more complex workarounds later on in the guide.
1. Re-plug the TV into the Power Source
If the static current is affecting the TV’s circuit, your TCL TV will not power on because it will fail to detect a good power signal. Should the remote be non-functional, powering on the TV using it will not be possible. In either case, re-plugging the TV into the power source and powering it through the TV’s power button will get the job done.

2. Hard Reset the TCL TV
If the firmware of your TCL TV is damaged, you will not be able to power it on. This situation may occur if the latest update was unable to successfully patch the previous installation. To resolve this issue, perform a hard reset on the TCL TV, which will erase all information and data stored on the TV.
With a Reset Button
Without a Reset Button
Reset Through Remote
Confirm that the remote is operational, and the TV is properly connected to a power outlet.
3. Reinstall Firmware
If you have or can arrange the firmware (you can request TCL support), then reinstalling the firmware will solve the problem. Do not use firmware available on 3rd party websites as it can cause security or privacy issues.
4. Stop the Recurrence of the Issue (Preventive measures)
If you have successfully powered on the TCL TV but encounter the problem again, certain settings on the TV may be causing the issue. To solve it, adjust those settings.
Change the TV’s Power Settings
Disable Screenless Service
Disable Fast TV Start
Change Brightness to Normal
Enable 1-touch and System Standby
5. Check for Hardware Issues
If you have tried all the previous troubleshooting methods without success, a hardware issue may be causing the problem. To determine this: If the issue persists after trying the above solutions, contact TCL support. If the TV is under warranty, claim a replacement one. Otherwise, get the TV checked for a hardware malfunction.
