always do the basic..
voltage checking sa mga output test point... pa wlang makuha... backward ang pagtroubleshooting

check supply pin ng mga parts.. pg meron reading at sakto.. mlamang sira na yun..

master manny palitan lang ulit ang mga nag open fuse o baka may resistor lang na mababa ang resistance ang bumigay.

dapat nga meron iyan lagi.


http://i1094.photobucket.com/albums/i453/aelexianempire/no14vonmc44603ap.jpg?t=1338869225

kong walang 14v sa pin1.
test mo ang P2 kong may 16v. if none - maaaring open ang 3510=33kΩ o shorted ang 6510=BZX79-C20

if yes - continue for P5. kong sakaling walang 14V
check 3529 at 3530. malamang open ang isa sa kanila.
kong good test naman ang dalawang iyan. sira ang pwm ic

hindi mo nasabi ang condition ng 6510. saan ka nga pala naglalagay ng ground? dapat doon ka sa - ng main capacitor 2508 at wag sa secondary. wag ka munang magpalit ng pwm hanggat hindi mo pa napapalabas ang mga standby voltage. may diagram ka na diba? test mo ang mga test point guide [P1-P12] post mo dito. tulungan kitang i eliminate kong saan ang may problema
