When i tried turning it on the standby light just flashes, says no command. Then it turns off then goes back on again to the flashing standby light and back to saying no command
Edit: to add i only see one button its in the middle of the bottom of the tv just behind the standby light
Might be dead or corrupted firmware. Not much to do. Either go to technician or flash firmware manually. TCL firmwares can be downloaded from internet, put it on usb stick, insert into tv, then plug tv into power socket while holding power button for atleast 5seconds, it will start flashing firmware.
