Samsung CT-3335V power problem
« on: April 08, 2010, 02:56:09 AM »
mga sir, may unit ako dito na ang sira ay ang regulator lang. everytime papalitan ko ito ng bagong regulator, nasisibak ulit yung bagong inilagay. putok din pati ang fuse. ano ang mga pwedeng check points dito? duda ako sa flyback nya, pero hindi ko alam mag-check ng flyback. salamat sa tutulong.

Boss hang mo muna collector ng HOT..

Tapos focus ka sa surrounding components ng Power supply section for shorted components.
