    This is the story of my life Sorin. You made a mistake this time... but I make the same mistakes in life, multiple times. I try to laugh at my own stupidity and for me it's just a hobby, I only work with other peoples (or my own) discarded equipment. No great loss except for the amount of useless appliances I have around the place. Even with your extensive skill and experience, these things happen.

    We all make mistakes, it comes with the territory. I used to beat myself up when it happened almost to the point of feeling incapable or stupid, like maybe I should not be doing repairs, especially when I thought about the waste of time and money coming from my pocket instead it going into it. But as you've said before, we are always learning and sometimes that comes best from making mistakes like this. Customers probably won't understand the hazards of this occupation but those of us who do repair work do. Knowledge & experience go hand in hand but we are all human & humans make mistakes no matter how good you are. Thank you for showing those of us who are less experienced than you that it is part of the trade. Ever 'accidentally' crack a panel on a $1500 TV?😖🤬 Sometimes learning can be expensive.🥺

    I think that desision is very good. I have never seen you check coil impedances in your videos. That was big curiosity for me because you always supply power from dc power supply and check the condition. I think that was wrong. Because if there was is a problem in motherboard, charger will cutoff. But dc power supply will not cuttoff and power go through the circuit and then it may be damage to components. As i think 😊. Please explain am i correct???

    Since the 386 motherboards, the chipsets have spare connections, and can be optionally soldered directly, with resistors or capacitors. The connections lead to ground, or to other chips. It seems to be setting connections, but there is no information what to do with them. These options are also in phones, and other devices.

    Presumptions often lead to mistakes, and the more we become familiar with particular items, the more likely we are to think we know where the problems are. Someone without experience of these circuits would have to work from basics, and not have this problem. Experience is usually helpful, but sometimes reminds us not to take thing for granted...

  • @ghostbiker7391

    correct me if im wrong but normally if a chip is blown up it's caused by short circuit or something, so if you gonna change that chip you need to check what was the cause or the new chip will blow too.

    • @winlose3073
      @winlose3073 Год назад +2

      that is true but the short can happen inside the chip because it has many components inside much like the thins outside so the chip itself might be shorted to ground and the current has to go somewhere or blow the chip and we've seen many damaged chips that are the only problem.

    Well actually i know what your mistake exactly is and I've been experienced these kind of fault. Unfortunately most of the 3.3v and 5 v alw ic are faulty and when you replace this ic , it will blow one of the high side mosfet especially high side mosfet of 3.3 vlaw and it will let enter the 19 v main power rail to 3.3 vlaw power line and it will blow up the ec chip and pch. You must disconnect the jumper output of 3.3 and 5 vlaw to prevent entering the 19 v to output and if these 3.3 and 5 vlaw were present , you would be allowed to reconnect the jumpers which i mentioned before.

      I did buy actually new PCHs a couple of times, and also used ones, the thing about boot guard is that not all brands and models have it activated, I heard some Dell do, in that case they RUIN the PCH, so that if you put them on another machine it keeps shutting off 30 MINUTES after turning on, not even a clean ME can save you, only a new (or otherwise unfused) PCH.

      Phone repairs kinda suck, customers always want their phones back ASAP giving you very limited time to look at them. Not to mention how difficult they are getting to repair. If you charge enough money its worth it.
