Repairing the 5V output from a Mastech HY3005D-3 (cheap import) power supply

The 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.
