Mezire siyal yo liy nan fen a opinyon nan tablo a inite (Goldfinger 26P ka konsidere kòm 13 gwoup, ki 8, 9, 10, ak 11 yo se L0, L1, L2, ak L3 respektivman). Èske gen sikui entèn entèn, sikwi louvri, ak opinyon HC244? Si kondwi a dèyè se nòmal. Si se konsa, mezire si D 'a siyal HC138 via HC244 se yon bagay nòmal, ak Lè sa a, kontinye enspeksyon an ak (2). Si ou pa, jije ke HC244 se move epi ranplase li ak menm kalite kous entegre.

Measure the line signals at the input end of the unit board (Goldfinger 26P can be regarded as 13 groups, of which 8, 9, 10, and 11 are L0, L1, L2, and L3 respectively). Are there internal short circuits, open circuits, and input HC244? Whether the rear drive is normal. If so, measure whether the signal input to HC138 via HC244 is normal, and then continue the inspection with (2). If not, judge that HC244 is bad and replace it with the same type of integrated circuit.
