update ko po kayo bukas sis nasa bahay ung unit.

@ sis noman75..pano ko ma identify kong may tama ung FBT, di na aku mka power up. Na try ko hung ung FBT at HOT, ok ung fuse d naman po full load un. Sa ibang unit ng sharp na gumagamit ng ganitong reg. d po nasisibak ung fuse. Iba to, pag standby ok, pagka power up dun sibak na.

hung up muna lahat ng load sa secondary at isaisahin ito kabit kung saan parti ng crkt puputok ang fuse,ceguraduhin na tama ang rating ng fuse mo.

kung ok yong regulator nito, sir paki check nalang main filter ecaps, small ecaps sa primary side direct sub mo nalang, posistor, brigde rectifier diode at yong chopper transformer... isolate mo muna PSU section!
