    Regarding the short; I probable would have check to see if the short was gone before soldering the new cap on. Time saver I guess one way and the other component saver. Nice video.

    When you had removed the suspect cap you had the opportunity to check the PCB for the short and measureb the cap for a short as well.

    First of all congratulations for your great TH-cam channel!
    I would like to ask if while injecting voltage into the circuit to find the short circuit a positive voltage could be applied to the ground rails of the motherboard and the zero voltage at probe pin. Thanks!

    Nice repair! I might look at getting one of those IR multimeters for my bench although I already have a UNI-T handheld thermal imager but my multimeter is an an antique Micronta 22-167 from 1992! :)

    If you record your repair anyways you could also just get yourself some box with many little compartments which you label with numbers and throw the screws or other parts in. During reassembly you can then refer to your vid and see "ah, battery was fixed with the screw in compartment 6".

    • @LearnElectronicsRepair

      Yeah I really like the ET13S multimeter/IR cam. I did review it and didn't notice all the features at the time. It even has a proper Me Bleep style diode test mode. There were some discount codes on that video which brought this down to about €130. They may be expired now but you can take a look. th-cam.com/video/liEOEgmPTm8/w-d-xo.html I thoroughly recommend this ET13S

    I knew it was a cap before you even open it up !! I do the same thing with the screws... on a other note Richard when will there be a follow up on that power amp ?? do you have a dummyload capable to test that amp ? do you need to build one ? will you make a video about it when you got to build one ? you need a dummyload that is 10 % more then the power that the amp can delliver at the outputs !! anyway great video 70% of the time it is a capacitor when a laptop won't boot

      with those poweramps you got to put it just before clipping and make sure everything tracks ok ... and to do that you do need a dummyload.. don't take it too lightly this is dangerous if it is not completely tested..

    I like that thermal camera. One think I hate about my multi-meter is that it does not remember what mode it was in the last time I used it and it goes to sleep after 15 mins, it still doesn't remember the setting when you wakes it up. I think all meters that have software running them should have options like this. I think that thermal camera/meter would be king if it also had Bluetooth, That's what I was looking for when I got my multi-meter.

    • @LearnElectronicsRepair

      This doesn't remember the last mode you used, but you can set it to always boot in whatever mode you prefer. It does have the Mr Bleep diode test function :-) It was about €130 with the discount codes th-cam.com/video/liEOEgmPTm8/w-d-xo.html

    Just wondering (newb here) when you have a few components next to each other not sure which is the hot one from the thermal cam, could you use something like a kids crayon and see which starts to melt it? No idea what temp is needed to start melting it mind.

    • @harveystedham9490

    I think the term injecting voltage might be better. I think you've even said on this channel that voltage is like pressure, just like pressing a syringe to inject a vac-... Uh... Vitamin booster. (Trying to avoid controversy but not sure if innoculations or addictions are a more heated topic). Current is drawn from the potential difference... Just like a phebotomist using a negative potential difference to draw a vial of blood.
    Side note: I had some blood tests done last week (including a lead test, just out off curiosity from all the soldering) and my phebotomist had a sign in her office that said "The only time it's a good thing to hear 'Is it in yet?'" and I think I want to find a new phebotomist.

    • @LearnElectronicsRepair
      @LearnElectronicsRepair  6 หลายเดือนก่อน

      Surely you apply pressure, therefore you apply voltage. The pressure can of course inject something like fluid or current

    • @markanderson2904
      @markanderson2904 6 หลายเดือนก่อน

      The syringe is like voltage. It applies pressure. The vaccine is like the current. It is injected. You don't inject the syringe.

    That's a lot of effort for the screws. Generally speaking, shorter screws go up front, longer at the back, the sides can be either long or short depending on the model, so just leave them until last and you'll be golden, yeahhhh!

      The problem I find is quite often I have to order some part which of course will take 4-6 weeks to get here as often as not and by then I don't know what went where unless I do something like this and then keep the sheet with the screws in the box with the laptop. Certainly if i do something like a PS5 I have a problem as there are so many different screws. Of course I'm always open to suggestions on how to do this better
