JVC AV-21BA17B schematic
Sino po sa inyo may diagram nito? Gusto ko sanang malaman kung ano regulator at ibang parts nito... Galing kc sa ibang tech to... tinanggal kc ung ibang parts...
Thanks!!
Thanks!!

Re: JVC AV-21BA17B schematic
anong exact chassis ?
mostly nka board imprinted/sticker printed sa gitna ng board
pero mas mlakas ang vibration ng bolang kristal na Chassis CW3
hula mode (^_^

Re: JVC AV-21BA17B schematic
Tama nga kayo master ultra...
Problem kasi nito master... Nung kinabit ko na ung mga parts... Pagka-ON... umusok agad ang 3.9ohms 10W resistor... Kasalanan ko rin master... di ko na-confirm kung tama ang mga parts nito...
Ano po ba tamang regulator nito? Ung binigay kasi sa akin STR W6756... ayun tuloy kasama sa sumabog! ... Sa thread na nabasa ko dito STR W6554A-F5 ung regulator ang nakalagay.... Eto ba ang tamang reg nito?
Anong dahilan ba't sumabog master ung reg at 10W resistor?

mhrap mgcommento lalot di ako cgurado sa chassis ng unit
mo
pkitignan nlng ang sticker like this one:
pki confirm nlng muna.. para maitama natin kng my mali man

kng yan ang nkalagay... cw3 yan... pki check kng ang mga placemnt # ng mga diodes sa psu ay d92x series nka imprint lalo na ang d922 (36v).. pg ganyan strw6554a ang isampak mo..
pg d93x series naman ay cw chassis yan na strw6756 ang reg... na gumagamit ng 27v sa d932

Re: JVC AV-21BA17B schematic
Sis d92x series ung naka-imprint sa board, so, W6554A talaga regulator nito....
Naging dahilan din ba sis kung bat nasira at umusok agad ung 10W resistor dahil maling regulator ang sinampak ko?

Re: JVC AV-21BA17B schematic
pwde kasi iba ang pinning ng reg na yan sa isa.. lalo na ang feedback
ano ba ang exact part number ng resist ang tnutukoy mo.. try nating eback trace

Re: JVC AV-21BA17B schematic
ung resistor dati na to.... nung dinala kasi sa akin ung TV na to walang regulator na nakasampak... kinuha nung ibang tech... nung kinuha ng may-ari ang piyesa sa tech.. sinampak ko... ayon pag-ON ng TV amoy sunog agad...
...yan ung resistor na yan... wire wound na 3.9ohms @ 10W... (CW3 chassis ginamit ko wala kasi akong exact diagram nito)
Ano kaya nangyari dito master?

Re: JVC AV-21BA17B schematic
bakit iba ang value ng resistor? puede rectifier circuit ang may problema dyan. check mo ang bridge diode (d901) baka shorted na ang mga pins niyan.

Re: JVC AV-21BA17B schematic
o tanggalin mo muna ang regulator lagyan mo ulit ng resistor. pag nasunog ulit. bridge diode nga iyan o mga parts na malapit sa kanya

...OK naman sis ung bridge diode.... di naman shorted.... try ko na lang muna ulit....

Re: JVC AV-21BA17B schematic
mkikiagree ako ky hertz.. lalot kng nkaunload ang power reg...
double check nlng sis... bka shorted ang dalawang diode sa bridge diode

sir hertz lahat ng tv ba pwede ba tanngalin ang regulator at e ON?Kailangan po ba e hang ang collector ng H-out?ano pa po ba ang dapat gawin?salamat?

Re: JVC AV-21BA17B schematic
Update lang... OK master ung bridge diode... Ang napansin ko lang pag nakasampak ung regulator merong reading ung bridge diode on both direction....
...chineck ko rin ung regulator shorted ung pin 1 at pin 3... pag shorted ba ung mga pins nato maging dahilan din ba master na mag-oopen ung 3.9 ohms 10W resistor ko???...

Re: JVC AV-21BA17B schematic
tanggalin mo sa board ang regulator at check ang mga nabanggit na pin. pag short nga ay palitan ng bagong regulator

Re: JVC AV-21BA17B schematic
Salamat mga master!!!...
Confirmed po... na maling pyesa at shorted ang pin 1 & 3 ang ibinalik ng dating tech!!!
