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 
information. DC-AC LCD Inverter...
