mga masters,na try ko na rin po palit ng strw5453
wala parin po pinagbago eh
sensitive tlaga model n to kasi try ko suplayan ng ibang powersuply ung 12v saka 115v nya mag click lang ung relay ayaw umandar,..parang makina cguro na my timing kaya d ko ma isolate kung sa psu b talaga problem nito,.
naguguluhan ako kasi pag standby normal lahat voltage nya
pero pag on ko bumabagsak na suply ng secondary maging ung output ng flyback
lalo pag adjust ko konti liwanag ng screen

ang hirap ng trouble mo. sabi mo nagpalit na kayo ng FBT at picture tube pero wala paring pagbabago. baka yoke na yung problem mo. ung vertical IC napalitan mo na ba?  |

agreed on topic: hmmm.. bumabagsak ang B+ pag may over lightness/brightness ? hindi kaya Xray protect yan ? @TS try nyu kaya suyurin nyu ang C board baka may open resistor kau jan... kng malolocate nyu ang X-ray protect circuit nyan try nyu disable muna |
