Flyback ringing
WebAug 9, 2024 · If the noise is coming from the television’s picture tube, you might need to check your TV’s hardware. A defective picture tube or flyback transformer could be causing the high-pitched noise. In this case, you may need to perform a factory reset on your TV. This process is relatively simple, and won’t wipe out any of your content. WebThe flyback topology (Figure 1A) results in significant cost and space savings for multiple output power supplies with high output voltage for power levels up to 100W. This topology uses a transformer, which is essentially a coupled inductor with multiple …
