Am rezolvat aceasta problema cu "caraitul " sursei !!!  Am incercat toate variantele gasite pe fourum dar fara rezultat. Zgomotul este provocat de transformatorul choper care,zic eu,dupa un anumit timp din cauza incalzirii lui in functionare ajunge ca ferita sa se desprinda,sa se dezlipeasca,cedeaza rasina sau solutia cu care ele sunt lipite. In stand-by frecventa scade iar vibratiile feritei incep a fi zgomotoase. Am demontat transformatorul de pe placa si am turnat in el superglue prin orificiile prin care s-a putut face asta. L-am montat la loc si s-a facut liniste deplina. :) Succes !!!
