Hello,I have just came across an issue with my Samsung HCN473W TV while watching the screen all of a sudden it started showing a huge amount of colours horizontial lines with a weird sound coming from the back then I could smell buring parts, so i opened the back and the IRF620 chip on the sub board looks like it overheated and if i wanted to could remove it with my hands.
I unplugged the TV as soon as I could and now when plugged back in I can only hear the sound no picture. I would like to know what the IRF620 part does and what else might have gone with that chip?
