mukhang my shorted sa secondary load side mo sis.. check mo ang H-out, FBT at avalanche diode. pag buo lhat yan at di pa rin mawala.. focus ka na sa psu side... lalot kng sa chopper nagmumula ang ingay

agreed sa mga nabagnggit ni sis Hertz
lalot kng sakto na ang B+ mo.. at abot na B+ pin ng flybak
ilan na pala ang nasukat mong B+ mo sis konektado?

on topic:
pg walang 9v ang Hvcc ng jungle... try mong ihinang/float ang pin na yan... pg lumabas...  pwde agad hatulan ang jungle kasi shorted na yan... pg di naman e back trace ang source ng 9v.. ngmumula yan sa LV reg na 4pins.. pwede my putol sa line o shorted na load
