NOTE: DC-AC inverter is used to generate very high AC voltage, to support 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 its 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
