Repairing the 5V output from a Mastech HY3005D-3 (cheap import) power supply
Posted by shopping-team at 4:00 PMThe 5V fixed output on my Shenzhen Mastech HY3005D-3 power supply died the other day, and so I took the device apart to investigate. The 5V regulator board had a bad solder joint where the bridge rectifier attaches to the PCB. I used a soldering gun to reflow the joints, and all seems good.
