Just Patching Up Dry Solder Revived A Dead ZEBRONICS Computer PC SMPS
This SMPS Model No. Zebronics ZEB-N450W was brought to me in dead condition. After opening and cleaning the inside thoroughly using blower and various brushes, the complaint was confirmed to be true by applying power and shorting the green wire to ground. On inspection, a lot of dry solders were seen. This was patched up very well. Checked for any defective or burst components on the board and did not find any.
As I was not having the other tools like Ring Tester, ESR checker etc. in the hospital, where I carried out the repair, I powered the unit after doing the dry solder patch up and lubricating the fan. It worked very well, adding a quick satisfaction to its collection bag! Here are a few pictures:
