    parts list spec and installed cap not the same

    I'm selecting replacement caps for a Dell model 2005fpw monitor. The main board has caps from ELNA, Samyoung & Samwha. The service manual parts list also includes board location. The parts list shows location c655 as "100UF KMG,RD 16V 20% FM2.5 T". I'm guessing that's a Samyoung KMG or a Samwha RD. Here's the odd thing—the installed cap is a Samwha RD 220uF 16v. I don't believe the monitor has ever been serviced but, not 100% sure

    Could this be a production line mistake, post production revision or maybe a re-worked warranty repair, which was resold as new? AND, what should I replace it with the 100uF indicated in the parts list or the 220uF of the currently installed cap?

    I wonder if this is why the monitor failed.

    I've attached the service manual

    More likely the PCB assembly version does not match your service manual.
    So what is wrong with the monitor?

      The only way to tell for sure what it should be is to compare it to another "virgin" monitor. The service manual doesn't have any revision number and it also doesn't spec what serial numbers are covered.

      From the schematic it looks like it's just a filter cap on the output of the 3.3V regulator. Shouldn't really make a lot of difference, but I'd probably go with the 220uf. You could always put a scope on the output and try both values.

        Samsung UN65JU67ODFXZA Version TD01 Schematic and Parts List
        by Mark D
        The TV is a Samsung UN65JU67ODFXZA Version TD01. I replaced the power source board and the TV is now working, but I decided to try and troubleshoot the old board to fix at the component level. Trying to get a schematic and a parts list has proven to be an issue. Trying on my own, I can't tell you how many times my Norton security has flagged sites as "malicious". I ordered a service manual from ServiceManuals.net, paid $16.99 and got 66 pages of everything BUT schematics and component parts list! Can anyone steer me in the right direction? Some of the surface mounted component parts...

        WH1000XM4, Sony headphones exploded view & parts list please
        by zen
        These headphones sell for between £250 - £300 so well worth going into.

        Need to identify earpiece swivel brackets LEFT/RIGHT.

        Right side damaged.

        Manage to modify original & now works quite well, but it does seem to be a weak point on these headsets therefore would like to have some in stock for future repairs.

        Firstly, would like to find out if Sony supply these as separate parts & if not then try to have them 3D printed.

        Can anyone help?

        SVOD4 PCB pictures + parts
        by 2elw
        Hey, I find it very absurd that the SVOD4 costs so much and has zero documentation. I had no other choice than to buy it to unlock ECs, if there was any documentation or firmware avalible I could've made it or something simmilar. Anyways here are some of the most important parts:

        STM32H723VGT6 MCU - It's a microcontroller by STMicroelectronics and its the whole brain of the SVOD4. It has flash memory for the firmware which can be updated by the SVOD4 program. Its also powered by the AMS117 which converts 5v into 3.3V. 7€ on AliExpress.
