Note: DC-AC inverter is used to generate very high AC voltage, to support to LCD CCFT backlight user, and it is also responsible for the control of LCD brightness. Avoid touching the DC-AC inverter area while the system unit is turned on.

Note: There is an EEPROM in the inverter, which stores it's supported LCD type and ID code. If you replace a new inverter or replace the LCD with one of a different brand, use Inverter ID utility to update the ID information.
