wait, may 60V lang pag naka angat isang paa nung 5.1M resistor
pag nakahinang na sa board wla akong ma read na voltage

Check mo 13003 transistor lang din yan karaniwan bce pin orientation or check datasheet. Wag ka nga lang mapatapat sa chinese oriented.

Kaya mo na yan mahuli kasi kukunti lang naman maski by component testing lang.

Magtabi ka ng mga busted na cfl, yung ibang mga power tranny pwede mong makahuyan.

PRIMARY
pinalitan ko ceramic disc cap mejo tumaas na kea naging 10 Volts (from 3V). Bakit ambaba?
try ko kaya palitan 5.1meg na starting resistor 10megaohms kc sa tester ko eh  :-\

SECONDARY
tapos inangat ko isang paa(ground) ng zener diode naging 15V na (from 10V)

5.2 Volts ba value ng zener kpag 5C2 nakalagay sa body niya??

halos lahat ata papalitan na  ::) kkkkkkk

5.0-5.2 Volts 1/2 watt (yung type na may range)

kami kasi old school(datasheet addict).  ;D ;D ;D

o bonus:

5v2 kasi karaniwan, or 1n something tapos datasheet na. Dapat meron kang product list ng alexan or projects and circuit na lang. May list kasi sila ng mga pyesa.

pinalitan ko ng C5V1= 5.1 V
no luck
mukhang palpak replacement ko ng 13003
pero mula nung napalitan ko yan tumutulay na yung voltahe mula sa 5.1meg pero ambaba 9v lng

oo nga kasi baka iba package ng orig sa replaced mo. 4 na package yan 13003A (dapat may A) ang  
TO-92 / TO-126F (3-2-1) -ECB
[TO-126 / TO-220] (1-2-3) BCE based sa datasheet.

sabi sa iyo be aware / observant.  ;D ;D ;D

meron nito sa ballast.

Gawin mong reference yung negative supply ng bridged diode.


patingin ng underside ng pcb tapos itabi mo sa component side.
