    Samsung 48h6400 / This capacitor failing?

    Hello,

    I have a Samsung 48H6400 that experienced a T-con failure, which I fixed by replacing the board. The TV is now working; however, upon further investigation of the power supply board (BN44-00709B) I found this capacitor on the "HOT" side (shown in the picture) with a rating of 120uF / 450V that troubles me. When I measured it with my Atlas meter, which I bought recently, it showed a capacitance of 106.7uF and an ESR of 0.37ohms. Isn't the ESR high and the capacitance a bit low for a rectifier capacitor? Unfortunately, Samyoung's datasheet from the official site does not mention the ESR of the capacitor (https://cdn.badcaps-static.com/pdfs/...11323e6efa.pdf). What is your opinion? Should I leave it as it is or replace it with a new one?

    Thanks.

      I don't know about ESR but capacity is ok.
      Datasheet says +-20% so 96-144 would be ok.

          Samsung C32HG70 - Blown Ceramic Capacitor (CP813)
          by NuclearSpartan
          Hi everyone,

          I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.

          The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.

          I don't see any other visible damage anywhere else on the board....
