Television and Home Theater

1 YEAR AGO, THE FOCUS WENT ON MY TV, IT SEEMED TO GET BETTER WHEN IT WARMS UP,  THEN ABOUT 1 MONTH AGO, THE PICTURE FLASHES ON AND OFF CONTINOUSLY, UNTIL YESTERDAY, THE PICTURE WENT BLACK.

THE INDICATOR BLINKS 5 TIMES INDICATING: CHECK (AKB)CIRCUIT VIDEO OUT; Q705,732,761 ON "C" BOARD.   ALSO CHECK; Q218,219,220 ON THE "A" BOARD.

WHAT TESTS DO I PERFORM TO CHECK THESE COMPONENTS ?

WHERE IS THE (C) BOARD AND (A) BOARD LOCATED FROM ONE ANOTHER ?

IS IT COST EFFECTIVE TO REPAIR THE BOARD RATHER THAN REPLACING IT ?
