Repairing the 5V output from a Mastech HY3005D-3 (cheap import) power supply https://tube.loping.net/videos/watch/1e2bf08f-7f5f-4b9d-bc83-936dd5ddc5d4 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.
