master ang alam ko lang ang isa sa mga laging nasisira sa smps ay ang opto, regulator, capacitor at resistor

SMPS?

kadalasan pag sinabi smps..,magkakamukha at magkakatulad ang mga parts na ginagamit..

voltage testing ba ang ibig mo sabihin.,testing point?.,how to check smps kung panu gumagana?..hmmpp.
maghanap nga muna tayo ng photos or diagram.,..

sir simple tip lng ,..mdalas po pag di sira ung fuse at hindi shorted ang power transistor moh, pero walang ocsillation ang smps muh check mo lahat ng high resistance value resistors madalas eh nawawalan na ito ng reading dahil sa sobrang taas n rin ng value at trabaho nito sa circuit kadalasan kc ito ginagamit sa driver circuit ng SMPS supplies lalo na ung 1M ohm up na values,.pero dont forget to check other components as well ,. un lng kc ang ginagawa ko madalas sa pag troubleshoot ng smps at kadalasan un ang problema ,and also pla check moh mga cold solders sir.. pointout sana makatulong sir,..

TS try mung ding pag-aralan ung post ni piezo dito abwt power failure
http://aelexian.4rumer.com/t132-troubleshooting-guidelines

regarding sa SMPS ng tv. madali lng namang i troubleshoot yan.. una mag check muna sa output kng may B+ ka ba(doon mismu sa secondary filter cap.. pag wla kang masukat. hugutin mu ang power cord. at sukatin ng voltmeter ang main cap/primary cap.
pag may stored V kang masusukat ay suyuring mabuti ang power supply circuit. unahin ang power reg.. kng umaabot ba sa kanya ang input(DC). pag umabot jan ay e-check mu lahat ang mga ecap. sa paligid nya. or direct sub na agad. sa mga resistor check mu din ang mga yan. baka may nag open lng.

pag di nmn nag eestored ng V ang main cap ay sa secondary out ka na mag focus baka may shorted sa rail line output nya..
