Hi all of them
i am facing a problem now a days
problem is that i had bought a power supply from market, and it makes PROBLEM from the FIRST day i had bought this
well PROBLEM is that, when i Swith ON the supply, display(DIGITAL VOLTMETER) works, but showing 0000 VALUES
when i vary from KNOBS, then nothing is going to happen
i open the POWER SUPPLY, and check fro the whole circuit that might be, if any thing burnt in it, then i must reploace, but every thing is OK from INSIDE
i study this supply since last week but uinable to LOCATE the EXAXT FAULT
if any one of you have any IDEA about this FAULT then must told me
i also mention that, i CHECK VOLTAGE from DIGITAL MULTIMETER at different part of power supply, it SHOWS (20V DC) which mean that transformer is OK....
so plz help me about this issue
