    xose1984 Год назад hi, i dont understand one thing, if the transistor was short why do not change it and you look for other components if they short to ground?
  • Electronics repair school
    Electronics repair school Год назад My mistake, its not the transistor on short, its was the transinstor pin to the ground! that transistor its on serial mode with 19v ,so even if its on short, the laptop still should work fine
  • xose1984
    xose1984 Год назад so if i understanding correctly ( transistor is a resistor who can change the value) the pin of transistor should not be ground and the video why saw it was going to ground, thats why looking for short to ground component?

    xose1984 Год назад nice thanks for responding sow quickly!!! and it was awesome video as always i hope you have i nice day

    Daveyk021 Год назад I assume the transistor survived the short? It is probably the master on/off control FET?

    Bruce Lee Год назад Hello you are very good see how many years of experience you have been studying in the field another question what equipments do you use how do you get the click? I subscribe see you are too strong I would like to have your techniques thank you
  • Video Stream
    Video Stream Год назад (изменено) I'm pionier in repairing motherboards so wanted to ask if you remove transistor in this video no need to put new one in place it will work fine without this one in those 3 line? Thx for answer
  • Andrew Lozano
    Andrew Lozano 5 месяцев назад (изменено) The transistor isn't shorted... Explanation: A transistor is more like an "electric switch", by applying voltage at the gate of the transistor you allow voltage through the switch(between the source and drain pins of the mosfet/transistor). You should never have 0 ohms between where power should be and ground. On the video, he shows one of the pins of the "electric switch"(transistor) is shorted to ground... in other words, on that side of the "electric switch" there is a short(low resistance between where power should be and ground) in the circuit somewhere. And the part of the "electric switch"(transistor) is what provides power to everything else on the motherboard.

    rene G 4 месяца назад the transistor was working fine, it was shutting down the excessive current due to the short caused by another component (the capacitor that went hot)

  • Krishna Chaitanya
    Krishna Chaitanya 3 месяца назад (изменено) @Andrew Lozano can you please explain why the 1st MOSFET (of 19V) and the other upstream components of short were making 'click click' sounds on the DC machine? Is that shorted capacitor connected to the 2nd MOSFET output? Is that why 2nd mosfet is showing the short to ground?

    The Observer 4 месяца назад I've always known, that on day when Russians will start to speak English, the world will get a lot smarter. You guys have very good skills on teaching people how to do things. Nice video! I like your style!

    michael george 3 месяца назад what a video! i have a similar problem with one of my laptop motherboards.very good video so informative
  • annafan83
    annafan83 3 месяца назад And I'm sitting here, trying to fix my S205 which immediately played dead after changing the hdd... power on all rails 1x20.7V, 2x 6.3V, 2x 3.3V... I think it's easy to solve and YOU makes troubleshooting look soooo easy... but it isn't. Great job on the hp laptop! Keep it up and thanks for your videos!

    Mr P 7 месяцев назад What liquid were you putting on the motherboard?
  • Martijn V
    Martijn V 1 месяц назад (изменено) lighter fluid but you can also use isoproponal alcohol
  • Stephen Zhu
    Stephen Zhu 3 недели назад @Martijn V why use lighter fluid?
  • Martijn V
    Martijn V 3 недели назад @Stephen Zhu has the same cleaning properties as isoproponol alchohol

    kostas dontsios 2 месяца назад My friend..i think your job would be much easier if you have a thermalcamera (Flir or Seek) to find very quick the hot component in the pcb. Great job by the way!
