Hang HOT.
Then measure B+
Pag tumaas sa 115v yung B+, baka yung filter cap sa secondary output line ng PSU, yung elect. cap mismo sa B+ line, baka leaky o dry na.
Pag bagsak pa rin B+kahit naka-hang nba HOT,  check individual parts sa PSU pati na trimmer, baka me nag change value o yung trimmer eh sira na (in case me trimmer nga)

Ok ba B+ mo? Three posibilities kung ok naman Pwr Supply

1) Me loscon - resolder muna
2) Hor. one line - magpo-protect talaga yan kasi yung masinsil na too bright one line eh masusunog yung phosphor ng picture mo kaya, hold down sya agad. Check mo vertical section. Kung me spare, actual replace vert ic
3) Me tama na FBT. Flyback testing dapat
