    Cap identification

    Hello everyone!

    I found a bunch of these caps in my Sharp LCD TV and would like to know if anyone knows the manufacturer or the brand name.

    It says something like "Dum? Con".

    I already googled the capacitor series, but only found capacitors of other manufacturers.

    Thanks.

    Re: Cap identification

    If this set was mine I would recap at least the power supply board and if you have a ESR meter I would check all caps that 100uf and lower to 1uf

    If you check low value UF caps and get a reading 1.0 or higher of ERS resistance I will check them with a new cap of same value and what the difference is this how good those caps are

    If you do not have an ESR meter then I would change all low value caps with new ones
    9 PC LCD Monitor
    6 LCD Flat Screen TV
    30 Desk Top Switching Power Supply
    10 Battery Charger Switching Power Supply for Power Tool
    6 18v Lithium Battery Power Boards for Tool Battery Packs
    1 XBox 360 Switching Power Supply and M Board
    25 Servo Drives 220/460 3 Phase
    6 De-soldering Station Switching Power Supply 1 Power Supply
    1 Dell Mother Board
    15 Computer Power Supply
    1 HP Printer Supply & Control Board * lighting finished it *


    These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

    1 Over Head Crane Current Sensing Board ( VFD Failure Five Years Later )
    2 Hem Saw Computer Stack Board

    All of these had CAPs POOF
    All of the mosfet that are taken out by bad caps

      Thanks for your reply.

      The TV set is working perfectly by now and it still has two years warranty, so I won’t modify or measure anything, which would involve desoldering, until it is really necessary.

      The caps I want to find out more about are in rather non-critical zones (audio amplifier and some signal processing circuit) — the OEM used at least Samxon GK and Capxon KF + GF capacitors together with one lonely Aishi RR capacitor in the power supply and LED driver section, so for a 240 Euro unit it could be worse.
