Fig-7 Fig-10 Fig-8 Fig-9 5 There are two methods to perform operation check using test mode. One method uses

16、 the head unit. The other method uses the repair jig. Because different operation buttons must be used for entering the operation modes and there are cases that the set does not run at all in the method that uses the head unit, the method using the repair jig is described as follows. 2-1.
