2.In this mode, press the OK button or the menu key to enter the selection, press the volume button to move the selection item up and down, and press the OK button again to confirm the selection after selection.
3.After entering factory mode, press the "Channel+" key or the "Channel-" key to move the cursor and select a different debugging project. Once selected, press the OK button again to start the project.
4.During debugging, if you need to exit factory mode, you can press the "Standby" key to exit.
Second, for some imported brand TVs:
1.Turn off the power, press and hold the channel + button and don't let go, and then turn on the power.
2.Once in factory mode, press the channel + or - key to move the cursor and select a different debugging project.
3.During debugging, if you need to exit factory mode, you can press the "Standby" key to exit.

Some TVs can enter factory mode via menu navigation. The user needs to press the menu button on the remote control to enter the main menu of the TV. Then, select Settings, select System Settings, or a similar option. In the system settings, the user can usually find the option of factory mode or similar functionality.
