In reply to Amendar.

Hi Amender,

Hard to find out those components just by referring to the board and nearby components. Sorry I don't get your meaning about answer or... on review pages. Could you elaborate?

Thanks Mr. Jestine,

Nice hints and experience.

Can board and nearby components help to find out a diode or zener one.?

How would be informed about the answer or ... on review pages, if any?

Thanks

HI Kamalakanan,

Place the black probe to center pin and the red probe on pin 3 output. The voltage is depends on what type of part number you use.

HI Chen,

Hard short circuit means if you test the connections with analog meter x1 ohm, the meter shows full scale. Sometimes repair tech refer hard short circuit as normal short circuit too. It depends on your preference on which terms you want to use.
