for me lng sis ha.. pg smps ang tnitira ko... applicable pa rin nmn ang s.o.p ng pgtrtroubleshoot ng psu ng tv. kya un din ang gnagawa ko.. lalo na pg wla kang secondary output

chenicheck ko agad ang primary ecaps before & after na unplug sa walloutlet
pg na eestored.. check ko agad lhat ng peripheral parts ng regulator. lalo na ang hv mylar cap at mga resistor specially ang mga high value. madalas my nag oopen...

Cnusunod ko nmn ang feedbak coil ng smps bka open na..
then ang bias ckt nmn.. ung malapit sa opto tl431 (^_^

pg yan ay ok lahat.. jan naku mgpapalit ng Regulator (pwm)

last hatol mo na yang PWM ic..
xa nga pla wag ismulin din ang current limiter ng opto. minsan change value yan.. at kng my trimmer ang smps board wag din iwla sa suspect.. pg knalawan o ngluko. mgcacause yan ng low output o di kya mkakapanginig sa output

Subok mo na ba ito sir? Subukan ko kasing gawin at ng masubukan rin. Baka kasi mafrustrate lang ako kung di ko alam gamitin o hindi naman talaga effective.
