ai sori now ko lng nabasa..
nko nangangamoy FBT na nmn eto lalot sa ganitong modelo
lalo na kng na try muna sis na edouble check ang mga:

C305, C307, R315, R305, R316, R313, R301, C313

sa pincushion nman ay inductor L401, L403, L404 at mga HV caps C401-C417

then wag laging kaligtaan ang supply ng 9V kng solid ba tlga (^_^

@sis triac ngpalit ka pala ng FBT?
ano sinampak mo? maraming ngkalat na fake sa merkado
duda ako sa FBT mo kasi yan lagi ang na eencounter ng mga ka sis natin sa kabila at mga ka tech ko sa ASC abwt sa heat... mgkakatulong sau ang mg add ng heat sink if normally ang lhat ng supply

sir ultra at sir arkin ito po yung FBT # na ibinigay ng LG service center sa akin BSC25-N1651 at ang H-out na replacement din daw is D2627..
@sir hertz ok po yung Electrolytic capacitor sa primary..
@sir ultra ginawa ko yung sinabi na mo,add ng heatsink mainit pa rin,try ko muna kaya sir ultra e replace lahat ng mylar capacitor?may duda ako sa mylar capacitor na ang value ay 6KV/183J sana makabili na ako nito..Is it possible sir ultra na nasira yung H-out ko?kasi d pa ako nakareplace ng FBT noon,bago na yung H-out ko shorted po kasi yung C6090..Noong nag pa test ako ng FBT,yung kuryente is jumping to another pin.salamat po sir ultra..

yapz possible yan sis... BTW klaruhin ko lng sa mga ganitong chassis dlwang possibilities na gamit etong board for Flatron TV (mlaki ang likod "ordinary picstube) at ULtraslim (slimtype ang tube)

dhil 21SA1RL ang model mo.. im sure Ultraslim eto tama? Correct me nlng if im wrong limot ko na kasi sa dami ng model na nirelease.. if im right... dpat ang HOT mo ay wlang dumper dpat...
so pwde jan ay C6090 or other like BUT11 ng Philips & etc..

ung mga D2627, C6093 at TT2170 ang mga my dumper diode ay compatible for flatron model.....

@sir ultra bibili muna ako ng BTU11AF,babalik po ako sa umpisa nito kasi may damper po talaga yung D2627.salamat po..titignan ko muna kung ano ang magiging problema kapag exact na yung H-OUT na mabibili ko investigate ...salamat po...
@sis baddypepito.salamat po..

for correction lng po ito yung mylar na sinasabi is 2KV lang pala hindi 6KV.salamat.. Razz
