nag reprogram po ako ng eeprom...nag power na sya kaya lang nong i-off ko balik sa dati.

@miel - tama po kayo 130v dapat ang B+...yong Vert. IC po napalitan ko na rin po bago pa ako mag post dito.

@ultrasonic - master, may milagro sa suggestion mo! nag normal na po ang operation...test ko po magdamag then update ko po uli kayo. sana po mai-explain nyo kung ano ang connection nitong shutdown problem sa jumper sa fusible resistor...hehe:)

@ultrasonic - master, nag shutdown uli. naintindihan ko na yong principle ng suggestion mo...ang AFC signal ay derived sa heater voltage..pag bumaba sya sa 6.3v namamatay ang unit...

Problem solved: nag lagay po ako ng separate winding sa core ng Flyback, 4 turns at pinutol ko galing sa flyback na 6.3V at inilagay ko yong bagong winding...and bingo!

salamat po sa lahat ng nagbigay ng idea...
