G+_Ben Reese Posted July 21, 2017 Share Posted July 21, 2017 It's alive! This monitor died a few months ago and I suspected bad capacitors. Broke it open last week and took a trip to Microcenter. They didn't have the 1000?f caps in stock that I needed, by I was able to make 2000?f fit. Link to comment Share on other sites More sharing options...

G+_Akira Yamanita Posted July 21, 2017 Share Posted July 21, 2017 Nice job. I hope that the picture of the electronics is the before photo. Otherwise, there are a few more that need replacement. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted July 21, 2017 Author Share Posted July 21, 2017 Akira Yamanita yes, that is the before pic. I should have, but didn't take an after pic. My solder joints weren't the greatest and both of the larger capacitors had to be bent over to fit. But those nearest 3 black electrolytic capacitors are the ones I replaced plus one that's not visible. (2 x 2000?f and 2 x 220?f total). Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted July 21, 2017 Share Posted July 21, 2017 Nice. I need to dig my workbench out from under piles of junk so I can do projects like that again. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted July 22, 2017 Author Share Posted July 22, 2017 Jason Perry that's why I didn't try this months ago. We're trying to clean up so we can sell our house, so it was a convenient time to tear it a part. Link to comment Share on other sites More sharing options...

G+_J Miller Posted July 22, 2017 Share Posted July 22, 2017 Nice! I once saved my 5 year old refrigerator from the recycling heap with a soldering iron. It feels good to repair! Link to comment Share on other sites More sharing options...

G+_todd zimmerman Posted July 23, 2017 Share Posted July 23, 2017 Ben Reese? how did you determine it was a capacitor at fault, and which one specifically? (Great job!) Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted July 23, 2017 Author Share Posted July 23, 2017 todd zimmerman Electrolytic capacitors bulge and sometimes leak when they go bad. The X mark carved into the tops is a designed weak point to prevent harmful explosions. In my case, the two larger caps were bulging the most (and you can see some corrosion on top of the left one), and I could tell the smaller two didn't have much longer.

G+_todd zimmerman Posted July 24, 2017 Share Posted July 24, 2017 Ben Reese interesting. I didn't know about the X. I know about the deformation/leaking/exploding, which is usually an after-its-to-late observation, but I didn't notice the deformation until I zoomed in on the second pic. Thx for the explanation.
