    Samsung LNT4042H Capacitor replacement

    Although I've done a lot of repair work before, I've never done capacitor replacement. I've got a picture of the capacitors I need to replace, but I have no clue how to select the correct kind, or from where I could/should purchase (the local RadioShack didnt seem to have the correct kind).

    I can gather that I need a 10vdc capacitor with a 1000micro-f...but when shopping I was overwhelmed with the choices.

    Trying to get this working for my grandmother. Any guidance is appreciated! Pictures below.

      Re: Samsung LNT4042H Capacitor replacement

      I have the same model TV, and did this repair in 2010. I ordered the replacements from DigiKey, part# 493-1497-ND. That DK part# is a Nichicon 10v 1000uf electrolytic cap. I forget how many it needs, I ordered 20 because I like to have extras for other projects. Clicking and power on/off issues were fixed after replacing the caps.

          Should move the thread to TV section.

              Where can I get compatible capacitor for replacement?
              by artvandalai
              Blew the capacitor on my analytical balance scale using the wrong power adapter. I need help finding a replacement compatible capacitor to buy. Will any 100uf 40v capacitor work as a replacement?

              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....
