    Hello from a newbie

    Hello everyone,
    I am a newbie, and just purchased an Auyoe 968 solder/desolder station and was wanting to know if I should purchase any more accessories to just work on installing capacitors for my own hobbies and friends systems on motherboards. I am retired (early retirement). and and love tinkering around with this kind of stuff. mabe getting a little side business going so I won't go stir crazy. Looking for some input. Sincerely, Jerry A Glenn

    newbie needs capacitor sizes. HP Spectre X360. schematic maybe available
    by tranquility
    hello, i am very new to laptop repair and generell electronics

    i have a HP Spectre X360 Convertible 13 - ap0016ng
    motherboard number DA0X36MBAE0 REV E

    massive burned and shortet mosfets. after removing them still shortet in the i think "main power rail"

    found a shorted capacitor. removed it and the short is gone.

    i want to try a crazy repair which is hard because the mosfets are like welded on one side to the track. is there a method to get this loose ?

    in this area another capacitor was shortet.

    Need Help Identifying Parts on a crossover and a few other newbie questions
    by UL161
    Hi I am trying to refurbish this crossover with some higher quality poly-caps/parts... The speaker is a in-wall Polk 65-RT... Key questions I have are:

    1) What in the world is the yellow part on the board (label is MET 1.0J 100V)?... Should I even consider replacing it?
    2) The 470uF cap.... Does anyone know have a suggestion as to where I can find a reasonable audio quality polycap near that value? (or at least 3 160s or the like?) { I don't want to spend $70 just to replace this one if I can) (maybe even someone looking at this circuit could even tell if this cap is important...

    newbie questions
    by cloghin
    Apologies if I am asking the wrong questions , but not sure how else to start:

    I have an A2251 / 820-01949 Mac book pro with no power, 20 v on USBC meter and 0.05 Amps. Following this link ( below)

    * Do I need to remove the board from case so I can access its other side ? The link calls for measuring PP3v3_S5 ( I suppose this is in diode mode with positive probe on ground) , but I don't know how to do that without removing the board from case.
    * I have the FlexBV board , are the values displayed in volts diode mode only ? Because my etekcity multimeter shows...

    Newbie about to dive in with the leads. Safety advice please.
    by Cappy Oligan
    I'm new to electronic repair. Trying to troubleshoot a Dell monitor that only has an AC port for power. I'm concerned about safety and not getting shocked. Should I order an isolation transformer and plug in the monitor into that and proceed with testing the board inside? Or should I get a DC power supply and limit the amps and connect the voltage to a pin somewhere inside where 19V DC is first expected? Or both? Thanks.

    eVGA GTX 970 - newbie fixing
    by Jofo
    Hello everyone,
    I am a newbie and this is my first repair attempt on eVGA GTX 970 that I bought from one guy. He said that his power supply died and took the graphics card with it and smelled smoke from the card too. When I took the card apart, one of the high-side MOSFETs was obviously damaged and there was a short on one of the PCIe connectors.

    The situation now is as follows:





    - The choke was already damaged when I disassembled the card
    - I've desoldered the high-side MOSFET "H" that was damaged, short gone...
