@coilankeurope: Digital TV goes black? Don’t blame the screen too fast. A black screen can start from the display power rail. When the DC-DC output has too much ripple, the TV may flicker, reset, or lose stable display output. A properly selected output inductor helps smooth current ripple and reduce the risk of power-related faults.#DigitalTV #Electronics #ElectronicComponents #PowerInductor #Inductor
