Based on field repair data, common symptoms of STR-F6267 failure include total shutdown, non-starting, and flashing standby indicators (common in Sony TVs using the BX1S chassis). A typical root cause is the IC being shorted internally (often due to lightning strikes or AC surges). To isolate the fault, technicians disconnect the horizontal output transistor (HOT) from the primary circuit and place a 60W incandescent lamp across the +B rail as a dummy load. If the lamp lights up, the STR-F6267 is functioning; thus, the fault likely lies in the secondary loads (Vertical IC or Flyback transformer).
The STR-F6267 comes in a 5-pin TO-220F (Full Mold) package. This isolated package simplifies heatsinking (no mica insulator required). Here is the detailed pin assignment:
