I tried the vise method and it worked. Then I proceeded with inspection. As expected, there were 4 badly leaking ELNA capacitors, so I replaced them all. Here is the list, if someone wants to order capacitors before opening the brick:
Few notes:
Only concern about the opening procedure is that I used a bit too much force so the case around the power jack cracked a bit and the case deformed. Luckily I used my SMD heat gun at 120 deg. C to heat up the case, and it returned to the original shape. Next time, I would rather use two pieces of wood instead of screwdrivers to spread the force more evenly.
Also since the capacitors leaked into the sealed case, the corrosion damage was extensive. The leaking electrolyte got under the solder mask, and even after cleaning it with hot soapy water and then drying it for a few hours, I didn't get it all out. Probably the best method would be to scrape all the bad solder mask off, clean it all, and apply some solder mask repair ink, to protect the copper.
- 16V 1200 micro F
- 16V 180 micro F
- 16V 82 micro F
- 50V 47 micro F
