This is my first post in this section and i hope that i will be get knowledge and help from experts because i am laptop technician.
today i have received a sony LED TV KDL32X650 for repairing .
the TV is dead no standby LED showing
i checked some measurement on PSU on CN6401 ..i received only 3.3v i think which is standby voltage and study some thread related and got a matching schematic not same but matching.
no other votage on CN6401 except 3.3v.
i checked the voltage on IC (A3810m) VCC pin 19 which have 3 volts only and this pin also showing with ground 15ohms which i think showing short. i disconnect only the VCC pin from circuit now that line receiving 12 voltage and no short circuit showing but the disconnected pin of IC still showing 15 ohms with ground pin which i think yhe IC internally short but what you experts are suugest....
the attachecd diagram is matching not same because in the diagram used IC CXA3809M which little different VCC PIN and also different PCB codes.
