Re: LG55UB850V no picture or audio - flashing LED's help please?
good work.. LD1900 lit on when there are video signal go to LVDS
did you look on the screen if there picture complete? if not
the slight voltage fluctuation at F1 and the buzzer sound you hearing much high caused by one bin or more cut or moved to aside at ribbon cable. if you saw the picture on screen fine then they are fine. but could be the LVDS cable.
BTW: the area you heat it are the DDR
