fuse na laging nasisira

Post by jam on Mon Apr 11, 2011 7:08 pm

mga kuya patulong po. may tv po kami. galing po ng japan. 110v po siya. accidentally naikabit po siya na hindi dumaan sa transformer. kaya po nasira. wala po kaming ibang tv sa bahay kaya po sinubukan ng kuya kong ayusin. binuksan po namin ang takip ng tv at sinilip po ang laman. nakita po namin ng kuya ko na sunog po iyong fuse niya sa loob. kinabukasan binilhan po namin ng bagong fuse at ikinabit iyong bago. pag plug palang po naming ng tv nasunog po ulit iyong fuse. bakit po kaya ganun ? mas lalo po ba naming sinira ang tv namin. naaayos pa ba ito ?

oo namang naaayos pa iyan. may dahilan kong bakit nasisira ulit ang fuse. baka short na iyong mga rectifier diodes. regulator ic o ano pa man iyong nasa power supply. basic check na lang muna

tama. ka diyan pyro.
@jam kong 110v operated yan tiyak may varistor yan sa loob check mo muna, dapat wala kang makuhang kahit kunting reading niyan kong i ma check mo ang resistance niya. dapat infinite.

naka connect iyan sa AC line.

agreed aku sa lhat ng sagot Basketball


kng di pa yan dumaan sa ibang technician. tiyak may varistor pa yan sa loob... try hinang at ikabit ang new glass fuse based sa original rating.

pag di pumutok at gumana ang unit ay confirm na varistor nga yan.


ngunit kng wla na yang varistor mlamang may tama na ang power reg or rectification circuit nyan

A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. A voltage regulator may be a simple "feed-forward" design or may include negative feedback control loops. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.


yan ang mga common power reg ng TV

maliit lang yata ang porsento na varistor ang sira pag 220V ang TV. nasisira lang kasi yan pag lumapas na 250~450V AC ang wall outlet.

kong pareho ang rating na pinalit. at pumutok pa rin, may shorted component na kayo. suukan mo muna ang mga suggestion sa unang pahina
