If the power supply is dead, the STR-F6267 is a common failure point. Ensure that Ensure the start-up resistor is not open and
The datasheet provides detailed specifications for the STR-F6267, including:
The is a reliable, if older, power supply IC. It is ideal for repairing classic CRT TVs, DVD power supplies, and industrial flyback converters from the 2000s. For new designs, use a modern IC like the STR-A6000 series or TOP26x family (higher efficiency, lower standby power). If you are repairing equipment, check the VCC capacitor and snubber diode first – they cause 70% of failures.
The STR-F6267 features built-in frequency jittering. By slightly shifting the switching frequency back and forth over a set range, the IC spreads peak EMI energy across a wider bandwidth, drastically easing compliance with strict RF noise standards.
