intre b+ si masa am 430 ohm valorea diodei iar invers 0,c-urile sunt schimbate corect,am verificat si defectele mentionate in revista service tv nr5 unde explica cateva din prob acestei sursa dar la mine e un caz diferit (toate bune dar nu functioneaza) si cu ic-ul original simtomul e acelasi cu care a venit.tda16846 nu genereaza impulsuri pt trz mosfet,modelul sursei e cel fara optocuplor.ce credeti ca ar putea cauza acest defect ciudat?
