Ang gwapo mo master,hehe,kau to?.wala po ocillation on fbt..Kc po ang supply ng vertical galing sa psu/hndi po galing fbt master.Nalilito rin po ako eh,,

TS pg bumagsak na b+ nabubuhay pa ba ng hndi bubunutin? may standby voltage ba eeprom?

m@r · « **Reply #32 on:** July 23, 2011, 08:52:36 PM »

sir TS palitan mo muna filter capacitor ng B+ at saka ecaps sa vertical... try mo din hang yong B+ check mo voltage kung stable at normal ba, suspect ko kasi dito FBT...

RhUNhA · « **Reply #33 on:** July 23, 2011, 09:05:28 PM »

sis kapag bumagsak ba ang b+ may 5v ba sa eeprom...hindi ba nwawala..

hackerz · « **Reply #34 on:** July 23, 2011, 09:20:27 PM »

normal B+125 hindi bumabagsak. normal din.eprom 5v/kahit hang pin8 ayaw parin mag on.natambay lang daw eto ng 1year,ako palang nakapag bukas./24v galing psu un nagsuply punta vertical..taz jungle at HDT.kong tama pagkaintindi ko.la kc mapa,

it depends sa nature ng trouble kasi if PSU ang problema kaya bagsak ang B+ eventually affected din 5V but bumabagsak ang B+ kasi nagprotect yong ckt. 5V is still there...

acer · « **Reply #37 on:** July 24, 2011, 12:14:57 AM »

ay ito pala yung sa secondary ng psu nakalagay ang vertical supply

hindi talaga mag supply ang ver nyan
check mo mula sa vcc vertical out papunta sa secondary baka may switch transistor dun check mo
pag wala pa rin attras papuntang system

flyback na siguro yan
