TV made a couple of loud snapping sounds and picture went out but still had sound. I unplugged the TV and plugged it back in now there is nothing. There's a "fuse"-(NL8001) that glows for a second then goes out. Any solutions?

Good day friend. check for an open resistor with high wattage and low resistance. explain how that nl8001 looks. does it have colored bands on it. give me a description of it. does it look burned. check your dc voltage on your main filter cap. it should be between 150v to 160ish v look in the horizontal section. check the horizontal output transistor, to see if there is about the same voltage as the main filter cap. thank you and please give me a positive rate.
