need model number. if you mean 4 flashes this is deceiving because 4 flashes is vertical problem but also with horizontal problem you will get no b plus to drive vertical and same fault code.check hot for short,possibly flyback faulty being a sony.vertical voltage is scan derived(from flyback) |

Cory's right, we need a model #. In most cases I replace the whole D board. If it can be done to component level we can try to help. |

EASIEST WAY IS TO REPLACE D BOARD.BUT YOU CAN CHECK COMPONENT LEVEL(HOR. OUTPUT,HIGH VOLTAGE TRANSISTOR AND SURROUNDING PARTS.SUSPECT FAULTY FLYBACK? |
