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"

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 ?

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... -
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... -
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.
