    Replacing a bad Cap with higher value.

    Hello experts people,

    First time poster but lurking the Forums for few days now. I'm a beginner hobbyist who's trying to fix what ever I can and learned along the way. Right now what I have is a busted 58inch LCD TV with backlight issue. Long story short, I kinda found the issue (or atleast on the right track) it's on the power board with bad caps (broken pin). It seems an easy fix, just replace it with the same one and away it goes, but for whatever reason I cannot find the exact value in my place or online store in my country. The bad Cap is 39uf 450volts in parallel. The closest I found is 47uf 450volts or 39uf 400v. I know changing to lower voltage is not recommended so my question is can I replace the busted 39uf to 47uf? This goes in parallel to the remaining two. Thanks in advance!

    Put the 47uF 450V in and call it a day.

      Yes, you can safely use 47µF 450V instead of 39µF 450V — just don’t drop to 400V.

          CapXon strikes again. But memes aside, yes. You can safely use 47µF. Just make sure the voltage is 450V or better. DO NOT DROP to 400V.

              Gotcha! voltage equal or above 450v. Online store min is 5 pieces so yes will replace all three of them.
