A Viewer called Matt asked if I would take a look at a very expensive GYS100.20 battery charger. He had taken it to a repair shop but they couldn't fix it. Let's see if I can figure out what's wrong and hopefully repair it!

I'm not an expert, but I do enjoy trying to fix things.

    Well Mick, what can I say, you’re an absolute genius, you really really are. I don’t think I can ever thank you enough. Thanks also for strengthening the connector with the hot glue, hopefully this will help for the future. You’re right, it is in and out of our vans all day everyday and the vibrations while in transit couldn’t have helped. Seems strange how it would decide to pick on that one connector lol. I think it needs a BuyItFixIt sticker on the top of it so I can tell the story to everyone that sees it and asked 😊 Again thanks a bunch. Skills like yours are far and few between. Take care. Regards Matt

    "Fanless technology", but the first thing I noticed when the cover came off was the fan at the left side...

    This channel, along with 'Mend It Mark', are head and shoulders above the rest in what is becoming an increasingly crowded genre. I truly marvel at the level of skill, knowledge and resourcefulness of these two gentlemen. And not a hint of ego. Thank you and long may it continue.
  • @gregjohnson5194
    Shocked that it was actually the display was the whole problem… nice job and repair.
  • @wb1340
    Mick, I could sit by your side for hours watching and learning. Saving pieces of equipment with sometimes no more than a few pennies of solder or a simple plastic connector. Simply amazing.

    Just as I came to the end of watching every episode of bigclive, the algorithm gods present me with hours more content to watch til the early hours. Love the channel - it’s the right amount of detail, professionally shot without any of the faff and waffle. Now firmly subscribed! 31, UK

    No problem with the bridged diodes at the beginning of the video? Surprised it was a display connector and that you found the fault so quickly, you're good brother. I'm always impressed by your talent, much appreciated. Great video, well done. See you next time.
  • @jimsvideos7201
    That relay makes a wholly satisfying ping, as an aside.
  • @Mymatevince
    Great fault finding as always Mick πŸ‘
  • @BruceBoschek
    Excellent detective work. Enjoyed every moment of it. Thanks!
  • @zaprodk
    Pretty good fault finding. I wouldn't have suspect the display board immediately!
  • @tyronenelson9124
    Its amazing how many people who work with electronics that are able to find faults but unable to rectify them, it makes me wander if they even know what they are doing in the first place?
  • @generaldisarray
    Excellent work as always sir It's a pleasure to watch you work!!! 1:39, ah, there's your problem, "Made in France". I mean we're all familiar with the disco light display on the back of a Renault, or Citroen, where all the lights flash and/or flicker once the indicator is activated?? You just can't trust them, I mean it says "Fan Less Technology" on the outside of the cabinet, but guess what's the first thing you see when you take off the top cover... A fan!!! Mon Dieu as the French say, Mon Dieu...🀣🀣
  • I swear these connectors are made with candlewax the way they melt if you go near them with an iron. What I do, is stick a pin-header into the socket to keep the pins aligned and soak up any excess heat. WHEN the plastic melts, the header stops the pins wandering.
  • @nigelman9506
    There is no better feeling than to repair something that shops cannot, well done, walk tall
