sa akin pong analysis para na rin po syang ic, dahil po function nya is to regulate the primary power supply via optocoupler. yun po B+ pin, naka-tap sa B+ line. yung G sa ground, yung C is control,naka-tap sa optocoupler . almost same function ng SE090, SE110,SE120,SE140,etc..mahirap po ma-test, kaya ang ginagawa ko, try to replace with new one.
