unahin mo muna ang H.line nya sis.. check mo ang mga supply ng vertical ic... pg kumpleto sunod mo nmn ang yoke.. change na rin ng secondary filter caps baka palyado kaya my effect sa audio...

....eto po some reading...

b+ - 110V
Vert IC input pin - 24V
Yoke - 24V, 24V

..na-observe ko master, pag pinatay ko ung unit may maliwanag na horizontal line na nalabas sa screen...

..posible din po ba na FBT na to?... halos nabalutan na kasi ng electrical tape ung FBT nya..

ngayon ko lang napansin. masyadong palang mataas ang input mo [pin4].
