Electrolytic Capacitors Still Giving Problem
I believe you have come across before equipment that you have repaired came back with the same problem-bad electrolytic capacitors at the secondary side. The equipment could work only for half a year till 9 or 10 months or so then the e-caps broken down again. You have replaced with the same rating of e-caps and this really have made you frustrated .
So in order to solve this problem, you just need to make sure get a good quality (or branded) electrolytic capacitors, a capacitor with a higher voltage rating than the original (say a 25 volt you put in 35 volt) and lastly you can even try to replace the 85 degree Celsius cap with a 105 degree Celsius e-cap. Make sure also the surrounding do not have any decayed glue and apply fresh solder to all surrounding joints. Follow this rules i’m sure your equipment could work for a longer period. What i mean is the e-caps rarely breakdown again.
