    Capacitor advice

    Hi all

    The time has come to replace the caps on the power supply board of my LG TV. It works fine when it is on but it is a pain to switch on which is a common fault apparently. All the caps currently in there are the original ones from the factory.

    The main filter cap is a Sam Young KMF which is for SMPS applications but the second in the circuit is a Sam Young KMG which seems to be a general purpose capacitor. All the rest of the capacitors on the board are Sam Young NXB capacitors which are for SMPS applications. It does not make sense why all the caps on the board are specific for SMPS applications with the exception of these 2 KMG ones (680uf 50v).

    I want to replace all the caps with Panasonic FR ones which seems to be a good choice for the KMF and NXB ones but am stuck on deciding on a suitable replacement for these KMG ones. Any ideas?

    I asume that the current Sam Young datasheets are still applicable for caps from 2011 anyway?

          TV is a LG 42LD490

          Power board is, EAX61124201/16 REV 1.3

          It is a 10 year old TV that has sometimes been on 24 hours a days and is still on its original caps so has done well and deserves a bit of TLC

              Onkyo DX-V500 Laser Disc Player - weird SMPS fault
              by dkneyle
              This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.

              Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...

              Huntkey HK340-72FP SMPS shut on load above 2 amps
              by abhishekkumar1902
              I have this Huntkey HK340-72FP PC SMPS where I am facing a strange problem where the SMPS shuts down when the load on any of its 12v output rails goes above 2 amps while the rating of each 12v rail is above 10amps capable.

              I have checked the following:
              1. All output caps are OK, and all output rails read correct voltages at no load
              2. All output diodes are OK
              3. NTC is ok
              4. Hi voltage cap on input correctly reads 150uF on LCR meter per the spec, also the bridge rectifier is OK
              5. No short in main switching MOSFET
              6. All other components...

              Mackie Th15 SMPS low Vout
              by madan1
              Hello,
              I'm troubleshooting a PA speaker Mackie Th15 (schematics attached).
              It is basically a smps with amp and some dsp.
              The issue is that on the secondary side I read +/- ~23V instead of the expected +/- 38V. Indeed all secondary side and feedback/aux rails are like 1/2-3/5 of the expected values.
              Q2, Q3, C35, C40, C33, C36, C41 and C42 were tested out of circuit with a component tester and read fine. Most of the other components on the primary were tested in circuit and seem to be fine. +HV to -HV on primary is ~330V.
              By the way, the ferrite core of L10 is broken,...

              Replacement for the Siemens Bakelite caps in an early 1980s SMPS
              by rewease
              Hi everyone,

              There actually was a time when early SMPS and late bakelite housed electrolytic caps coexisted in high end industrial gear. A friend of mine just got himself a CNC milling machine form that time with its first set of now 41 year old caps still installed in the PSU... and it's malfunctioning.

              Two of the caps have already leaked slightly onto the board. I have not desoldered or measured any so far but they should qualify for replacement.

              Now I'm wondering what to put in there as a replacement. First idea was state of the art low-ESR Nippon KY,...
