TV CR (TVCR) flyback transformer due to interference from noise gaeseonhoe

摘要

A noise correction circuit according to the flyback transformer interference of the subject innovation are flyback han cause interference to the low-color sub-carrier of the V CR by the horizontal period the flow of the transformer so as to prevent generating a colored band noise to appear on the screen TV CR (TVCR) It relates to, and the prior art flyback transformer noise components shield (SHELD), the amplifier section 4 and the drum 3 in order to improve the but flyback block the transport flow, or shield the flyback transformer around by the shielding action and the cost is increased in accordance with a chassis structure, there is a problem that do not sufficiently improved only by the noise shield.; The subject innovation is one to this image switching vice and combining unit in order to solve the conventional problems such as this by further connected to the trap portion and the resonance portion to trap a certain frequency band of the flyback transformer high-frequency component removed to the flyback transformer high-frequency interference components that apply to television CR.
