OT ka na.. pero sasagutin ko na rin. actually sa sevice mode lng yan. malalaro mu na ang audio out. kng buo ang mga Audio swicther

try this setting bigay ni sis pete kng tugma lng ang modelo ha...
Default setting ng TCL-2027u

pero kng hardware probz na yan mas maganda
gawan mu yan ng sariling thread at tuturuan kita ng magic how to modify to hear the sound (^_^)

on topic: nasan na kaya si TS ? naayos na kya nya ?

kadalasan sa TCL 12v-20v lng tlaga yong b+ nya.umaabot lgn ito ng 110-120 pag nakasysytem power on na.klangan mo diagram nyan,pra mtrace mo yong switching transistor.wla namang connection ang memory sa b+,dyan ngkamali yong ibang technician,akala nla knocontrol ng memory yong b+.dna kc nla snusukat yong b+ bsta gumgana na.kaholito,try mo muna plitan yong memory,kc sa tngin ko hindi nag power yong system mo.
