    EEVblog Episode 347 - Samsung SyncMaster 204e LCD

    Dave Jones does a teardown and repair of a Samsung SyncMaster 204e LCD. No surprise to us that the culprits are bloated Capxons.

    Bloated CapXon caps?? NO WAY!
    ...
    Unfortunately, I will have to watch that video another time. Currently sitting on a PC that isn't quite capable of YouTube

      I saw it... I cringed when he put in those "Low ESR" garbage caps he bought...

      I was also a little disappointed that he missed the opportunity to discuss cap ripple and ESR by showing the datasheets and demonstrating how to find equivalent series replacements that match the originals. It seemed like a very rushed, unprofessional job when he didn't even need them working right away and could have made much better use of his blog by repairing by example.

      OTOH, I did learn from him that some of the components have the tack on them for a reason. I always thought that the tack was there for the flow soldering to hold the components down so they wouldn't bob up during the process. I didn't understand some of the component identifications by the terminology he used (He varies his terminology sometimes), but he did say that the reason for the tack is because some of them actually oscillate and the oscillation can fatigue the solder joint.

        He needed to fix them fast because he needed them for Teardown Tuesday or for some conference he goes at this week or next week - I'm not sure now exactly when that expo/conference is and I'm too tired/not interested to look it up.

        Yeah, he knows those capacitors are crap and he says in the video but he didn't have time to wait for Farnell to ship him capacitors.

        I guess I also feel it was a rushed up video, which doesn't really "teaches" anything while it can potentially give people that don't pay attention bad ideas.

            Samsung Syncmaster 740BF repair
            by soopacrucial
            Hi folks,

            I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:

            Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of. By pressing the power button I do remember I could at first get it working again but eventually the problem would come back. At the time I had read about...
