focus lang tatay sa vertical section muna...
try to float input pin (pin4) ng vert. ic at mag insert ka ng signal.. small audio pwede na... pag may reaction at unti unting bumubuka ang one line,,, wala sa vertical section mo ang problema kundi nasa ibang section (jungle, eeprom & etc.)....

pero pag walang reaction nasa vertical section nga ang problema mo tatay...
check mo agad ang supply mo pin6 & 3 dapat parehong solid yan at stabled..
pag meron iyan check mo naman ang output mo.. def yoke partial test (resistance check) at supply nito alam mo naman ang voltage reference



pag ok ang mga yan tatay..  isa isahin nyu na ulit lahat ng peripheral parts ng ic..
copper clad ng pcb baka may hair line crack or loose con... pag ok na lahat at ayaw pa rin.. palitan na bagong working na vert ic...

pag ayaw pa rin... isauli mo na yan tv sa may ari tatay... ayaw nya  yatang mag paayos sayo  ;D

kung yang resistor na yan sis nka series sa suply ng vertical ok lang yan palitanb mo ng 3ohms pababa...fusible resistor lang naman yan masisisra tlaga yan pag shorted na ic mo or may problema sa vertical mo..nasubukan mo bang direct sub ng yoke...o baka naman may nagkadikit...suyurin mo sis sa vertical lahat bka may leak...tsaka dapat kung maari original na vertical gamitin mo...bka makatulong... :)
