thanks!, pero ganun pa rin sir...

nag-try ako i-swap ang output ng GREEN sa BLUE using jumper wires, nawala ang GREEN and lumabas ang BLUE
so ibig sabihin working ang BLUE gun at may problema lang ang circuit...

eto nga pala voltage measurements ng RGB directly sa CRT

R=122VDC
G=125VDC
B=71VDC confirmed na meron nga problem sa Blue section
*nag-check na ako and nag-swap ngmga transistors ng RGB, resistors.., etc ganun pa rin

measurement from IC
R=2.4V
G=2.4V
B=3.6V sira na kaya IC ko nito?

dapat dominante ang blue nyan kc mas mababa ung boltahe or saturated ung blue?correct me if im wrong.,float mo muna ung blue gun saka mo measure ung ckt output second swap mo naman ung blue green ng ic pag lumipat ng trouble ic nga.pero???>>> me kinalaman din ung system dyan kaya da best din na palitan mo muna ung eeprom kc andun ung rgb parameter nyan.
