sis jopaw hindi madali masira yang transformer.Check nyo muna kung may B+ kayo,kung wala pakicheck yung HOT baka short..kung may B+ check nyo naman lahat ng secondary voltage..sana makatulong..sory wala po akong diagram,baka sa mga master natin meron..

huwag lang focus sa primary side ng transformer. dapat meron xang secondary voltages,, 125 at 12v

master hindi madaling masira ang mga chopper transformer. may tanong ako master nag iipon ba ng DC ang primary capacitor? pag ganyan ang status focus lang tayo master sa power supply

bos djfel; wla po po ma read sa b+
bos triac; wla rn po ma raed sa collector ng horizontal
bos electro: nag iipon nmn po ng voltahe ung main cap.
tnx sa mga coments, xensya n sa abala hehehehe beginer lng po sa ma2lungan nyo po ako tnx ng marami...... Very Happy

palatandaan na hindi nga gumagana ang regulator.

wag mo munang paghinalaan agad ang regulator mo. wala ka kasing primary B+ 310VDC sa pin1 (drain)

ito ang example ng ibang tv model na gumagamit ng 3s0680rf


basa ka na rin ng datasheet

mababa yata ang pin3 (12v) mo.. try mu yang echeck. sundan mu si sis djfel.. resistor na change value hnapin.. sali mu na rin lhat ng peripherals parts sa pgchecheck bago hatulan ulit ang Reg...

@hertz anong wlang supply sa pin1 ? eh ang laki ng post niya
