CN2  CN601            Supplies 5V from the power board to the main board and transmits the PWM output from the
                      power board to the inverter.
                      * Possible problems: The No Power and Blank Screen errors may occur.

CN301 ~ CN304         Transmits the lamp current (6mA ~ 7mA) generated in the inverter to the panel lamp.
                      * Possible problems: A Blank Screen error may occur.

CN1                   Transmits input power of 90V to 263V to the power board.
                      * Possible problems: The No Power error may occur.

CN102                 VGA signal input terminal
                      * Possible problems: The No RGB Output error may occur.

CN3                   Connects the function board and the main board.
                      * Possible problems: The No Power, No LED Screen, No OSD Operation, and Abnormal OSD
                        Operation errors may occur.

CN202                 Transmits the LVDS signals from the main board to the panel.
                      * When a problem occurs: The Blank screen and No power errors may occur.
