Internal WiFi Module (WLAN Adapter)
The D-Series utilizes a discrete WiFi card that is prone to hardware failure due to thermal stress. When this module fails, the TV will either not see any networks or fail to maintain a handshake with the router even with the correct password. Replacing the module is the primary mechanical fix for hardware-level connectivity loss.

Main Board
If the WiFi module is replaced and the issue persists, the failure likely lies in the communication bus or the voltage regulator on the Main Board that supplies power to the WiFi card. In budget models where the WiFi is integrated, the entire board must be swapped.
