To enter service mode on a TCL 21F5 model TV, you will need to follow these steps:

1. Turn off the TV using the remote control or the power button on the TV.
2. Press and hold the "Menu" button on the TV.
3. While holding the "Menu" button, press the power button to turn on the TV.
4. Release the "Menu" button when the service menu appears on the screen.

Please note that making changes to the service menu can cause permanent damage to your TV if done incorrectly. It is recommended that you only make changes to the service menu if you are familiar with the settings and have proper knowledge of the TV's inner workings.
Also, It's better to check the manual or contact the TCL customer service for more details.
