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 its supported LCD type and ID code. If you replace
a new inverter or replace the LCD with a different brand, use Inverter ID utility to update the ID
information.
