[sabre504]

Hi have taken power board from my old monitor and replaced it
now the one i have left over works but the transformer buzz s

Question is would the power mosfets cause this as i think one or both maybe faulty
Have put pic on but this is not the actual board but one the same

If the monitor works it's most likely the transformer itself at fault. Brush it with lacquer, let it dry, and the noise will go away.
