sa pamamagitan ng resistance x1,yung input na pin 1&2 suplayan mo 3vdc with series resistor na 100ohms.
test mo pin 3&4 kung mag karoon ng mababang resistance.pagwalang supply sa pin1&2 dapat wala kang masukat na resistance sa pin 3&4.nagbabagu rin ang resistance nyan depende sa supply sa input.
check mo rin ang mga resistor sa psu baka change value.

mga master p help po ung TV na inaayos ko

unang sira nya dead set po..

pinalitan ko po mga pyesa na:

1.)STR 5741
2.)horizontal transistor
3.)lahat po ng electrolitic n capacitor maliit at malaki
4.)lahat po ng resistors at diode s primary power supply
5.)checking po ng mga pyesa

pgktpos ng lahat ng ginawa ko sinaksak ko po. .

pumutok ung STR talsik nga po ung part ng STR

ano p po kya possible n sira nito?

double check mo mga parts pinalitan mo sa psu, baka may mali,,, baka sira choper u

tama po ang regulator n kinabit ko master...

pno po b malalaman kng autovoltage ang primary sis amianan?

ncheck ko n ang chopper buo dn po..

bka po my diagram kau n2 mga master..

BhongTech · « **Reply #31 on:** January 31, 2012, 03:14:57 PM »

sir may nakalagay naman po sa likod o back cover ng tv (90vac to 240vac)AC input.
kung nasa 375vdc yung filter ecaps sa primary malamang autovolts po yan.
wait ka na lang sa mga master baka mayroon silang schema nitong model.

kleinrio · « **Reply #32 on:** February 01, 2012, 03:54:42 PM »

opo master auto volts nga ito... napalitan ko na nga rn po ung ecaps s primary... nkabili nrn bgong STR... kso natatakot p magsasak sa kuryente bka kc pumutok ulit STR mahal pa naman un..

"an electric shock a day makes your nervous away"

sis gamitin mo ang motto mo

sana mka tulong

at saksak muna sa 110v kung meron ...

NORTH LUZON · « **Reply #35 on:** February 01, 2012, 09:40:38 PM »

saka jugot agad pag mali ang b+
