[SatEmpire]

To access the TCL service menu, press the Settings button on your remote, navigate to Picture > Contrast, and then enter a code like 9735 or 6428 from the remote control without any pauses. Some models may require a different code or sequence, so it's crucial to find the correct one for your TV's specific model and operating system. It is strongly advised to take a picture of any existing settings before making changes, as incorrect adjustments can cause the TV to malfunction.
