damaged, after replacement a complete re-alignment of the set will be necessary. Therefore, when carrying out convergence drive
signal checks and measurements please use the relevant pins at PCB connector BK04.
Prendre grand soin lors de mesures sur les points de IK02 et IK03 à ne pas créer de court-circuit.Si celà arrive IK01 sera détérioré
et un alignement complet de l'appareil est nécessaire. Pour éviter celà effectuer les mesures et contrôles des signaux des drivers
aux points du connecteur BK04 de la platine CSB.

Messungen um IK02 und IK03 müssen mit besonderer Vorsicht vorgenommen werden, da bei eventuellen Kurzschlüssen IK01
beschädigt werden kann. Nach einem Austausch von IK01 ist ein vollständiger Abgleich des Gerätes notwendig. Deshalb sollten
zum Überprüfen der Konvergenz-Treibersignale Messungen an den entsprechenden Pins des Verbinders BK04 durchgeführt werden.
Prestare molta attenzione in modo da evitare corto circuiti quando vengono effettuate misure sui circuiti integrati IK02 e IK03.
Se ciò dovesse capitare verrebbe danneggiato IK01, nel caso di sostituzione di tale componente diventa necessario effettuare un
completo allineamento. Per cui quando si devono controllare i segnali di pilotaggio di convergenza utilizzare i relativi piedini del
connettore BK04.

Nota :
La forma dei segnali D R/G/B, RV, RH, GH, GV, BH e BV viene fornita solo a titolo indicativo. La forma può variare in base alle
regolazioni di convergenza e alla sincronizzazione dell'oscilloscopio.
Nota :
La forma de las señales D R/G/B, RV, RH, GH, GV, BH Y BV se facilita únicamente para información. Puede diferir con los parámetros
de convergencia y la sincronización del osciloscopio.
Debe tener cuidado de no provocar cortocircuitos cuando se efectúen mediciones alrededor de IK02 e IK03. Si ocurren,
IK01 se dañará o destruirá. Después de la sustitución es necesario hacer un reajuste completo. Por lo tanto, cuando haya
que comprobar o medir en las señales de convergencias, utilizar siempre las patillas correspondientes del conector BK04.
