When soldering ic and pushing down on ic maybe grounding pad pushes some solder out to short other pins. Do you use a thermal camera for diagnosis of short or missing voltage?
gawin mo sir, check for short sa mga caps na katabi nya...kung meron 0.5 sa mga caps, ok sya. pero kapag both ends ay 0.0, meaning may issue. try mo i remove ang regulator IC, then check mo ang caps. kung nagbago ang value ng caps, from 0.0 to 0.5, na pinpoint mo ngayon kung saan ang issue.
@@clpcrandomrepair thanks po, meron akong shorted resistor. Naka standby yung 3.3v at 5v nya hindi lumilipat sa coil. Siguro dahil sa short. Palit na siguro ng IC. Sure ako yung IC mismo ang shorted. Nagshoshort po ba resistor?
Sir San po Ang Bilihan ng pyesa mo Katulad ng Mosfet Charging IC at Power IC baguhan po kasi ako nag hahanap ako ng Supplier More Video sir Godbless po 😇

i just use 99% alcohol, diode mode tester, resistance to ground measurement, for short to ground diagnosis
tanong lang boss ok lang ba magpalit ng ic basta parehas ang code sa first line ? or dapat same lahat ?
mas ok same.
minsan kasi nag iiba ang frequency nila, magkakamali ng timing.
kung ako lang tatanungin mo sir, same na lang para safe ka.

Yung power controller po ba yung pinalitan nyo? First IC na connected sa mosfet. Nanjan ba yung reg3 at reg5?
yung mismong regulator IC sir...kasi walang 5V or 3.3V na output

hindi, check schema, king ilan value ng ohms nya. then compare. 5% tolerance reading ok pa. lagpas dun palitan mo na
The capacitor on nectoken is revirsed polarity so it will leake
correct. someone forgot to check the polarity.
I have a question , please
ano po
@@clpcrandomrepair Do you have videos about testing all the parts of a motherboard using avometer and schematic diagram ?
usually, you can find 2.8V , 20V, 24V, 6V around the BQ chip
@@clpcrandomrepair You didn't answer my question !!!!?
i dont have it sorry, I dont have a high end pc and that camera that can handle both things at the same tine

Marami nyan sa shopee at lazada. I think mura yung power controller IC. 5 pieces per order.
Tama. Shopee lazada
