WebAug 30, 2012 · From Equations (1) and (2), we can see that voltage stress of the flyback-type clamp circuit is less than that of the boost-type one, making the flyback-type clamp circuit more attractive. In this study, only the flyback-type clamp is considered due to its obvious advantages. 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.
