hintay namin model

yung diode na yan naka parallel sa b+ parang zener ang marking sa board.nasisira yan dahil sa mataas na b+
kapag smr40000 and his0169 ang gamit nyan palitan mo pareho at lhat ng maliliit na ecap sa primary side

agree... check mo din horizontal section yong h-out 'coz i think yong chopper transformer yong pinagmulan ng beeping sound... i have experienced like it before what causes the chopper to produce a beeping sound is a defective flyback...
