Key on the Service R/C to enter the ‘Ez - Adjust’ and select
the ‘3. ADC 480i Comp1’.
Pressing the Enter Key to adjust automatically.  

(4) When the adjustment is over, 'ADC Component1 Success’

is displayed. 

(5) If the adjustment has errors, 'ADC Component1 480i Fail’

is displayed. And error massage(‘Component1 Not
Connected’ or ‘Not Valid Format’ or ‘Check Signal Status’)
is displayed for 1 second.

(1) Check the connection Component1, RGB to the Test
