back trace ka lng ulit sis sa + rail ng vert. supply
kng ok ang rect diode 6402 (hndi open/leak),
ok ang filter ecaps 2410 (hndi short)
ok ang fusible resist 9403 (hndi open)
ok ang copper clad from fbt pin going to 2410

mukhang fbt na yan..
try mung ngang tanggalin ang pin na yan (pin5)
tapoz insert ka ng external supply na 12V ac gamit ang ibang supply.. or kng mtygaan mu bubod ka ng wire sa ferrite core ng FBT para mkagawa ka ng 12V secondary out.. for testing purposes lng.. kng titino ba ang unit mu..
