ano part number ng orig?
ang ano ang i-replace mo??
saan galing yung ipapalit mo?? mas-maganda sa monitor din

pero bago yan nag-resolder kana-ba??
check muna natin FEWT na yan
kailangan hindi leak yang pin2 and pin3,
pin1 and pin2 ,.. observre mo lang kung mabilis ba uminit
palitan muna ,, goodluck poh..

sis yung Irf630 mababa ang drain to source breakdown voltage nsa 200v samantalang ang Irf740 nsa 400v.paki-try i-short ang gate at drain tapos try u uli tester ang drain at source vice versa.dapat isang direction lang may resistance at pagganun good yan.

N-ch fet yan.ang tamang pagtest i-set u tester sa X1 tapos yung red probe steady sa sa source(pin 3) tapos yung black probe i-tap mo ng isang beses sa gate(pin 1) tapos tester u ang drain (pin 2) at source(pin 3)magkabilaan me resistance yan at magkaiba ang resistance nyan at para mawala resistance i-short ang drain at gate.

tama ka sir bhong may tamang pag-test sa FET katulad din sa sinabi mo
kaya kailangan i-descover mo kung paano mag-test jan TS...

pero kung alam mo paano pag-test sa FET at leak na talaga palitan muna yan
