Note: DC- AC inverter is used to generate very high AC voltage, then
support to LCD CCFT backlight user, and 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.
