Guest Posted December 11, 2018 Share Posted December 11, 2018 (edited) Ori condensatori uscati, ori scalerul BGA de linga mufa lvds cu probleme, incinge bine toti condensatori(si cei 3 din cutia de tabla) cu uscatorul de par(70 grade)si vezi ce zice, la fel si la scaler incalzit cu suflanta 150 grade/1 min, apoi daca e cazul reflow.
