Two Power supply Boards
The LED TV has two Power supply boards. Here we have a G7 power supply board that provides power to the backlight inverter or LED driver via cable. The two power supply boards are joined to each other. The second power supply is called the G6 power supply. The G6 power supply connects to the main board and to a power-saving switch located on the outside of the TV. One goes to the switch and another connection goes to the main board.
The Backlight inverter or Led driver has a cover that has to be removed by unscrewing, this is what supply power to turn on the backlighting for the TV. LED TVs are the same as LCD TVs with one exception, the cause of illumination for the screen and the board that makes that illumination.LED TVs uses CCFLs, cold cathode, fluorescent lamps. The screen though an LED TV and LCD TV are the same.
T-con board is covered, so if you are doing any repairs to the backlight inverter/ LED drivers or the T-Con board, you will want to remove the covers for each of them before you replace the board. Removing the covers can be simply done by removing the screws that hold them to the panel. T-Con board actually takes the image and sends it to the panel which makes it'll show up on the screen. The T-Con board is connected to the LED driver or backlight inverter and then connects to the panel by two cables.
