My boss tell me to fix a 1u power supply, i've tried and failed and got some questions.So beg for chings helping hands.Thx.
No brand 1U power supply X 1.
Once disassembled 2 output side 1000uF 10V capacitors were found big tummy and got replaced.Also 2 output side coils have burnt mark (Some wire turn black. As shown in photos).When 220V is connected, 5VSB -> 4.99V (Consider to normal ?) when tried shorting green and black wire to start up, That 2 coils start smoking ................ Immediately power off and dare not try again.
1. Are these type of coils specially made to each cow model? How can one get replacement ?
2. Anything to check before replacing the coils ( If i can get them) to prevent further damage ?
