    Trinoculars
    by Brendon@aa
    Can anyone point me to a review or suggest a good microscope or trinocular for a semi serious tech getting into SMD?

    have been watching Richard from Learn Electronics Repair and he recommended a trinocular simulfocal from Amazon

    I also saw a review from a guy that had his meter (think it was a fluke) display in his microscope lenses

    any tips appreciated !...

    ASRock B560 Pro4 doesn't start
    by johnnys25s
    Hy there.
    I have a ASRock b560 Pro4 MoBo that doesn't power up anymore after CPU swap. I used (my) CPU to test another (broken) board and after put it back, my board doesn't start. I've tested that CPU again but it's ok. I even bought another one for testing. I also have 2 PSU for tests. NO bent pins and no mechanical damage.
    I have different voltages on the board (in some places) but it doesn't start, at all.
    I have the schematic but I don't know what to do exactly with it. I have some skills and I can measure things. I need help to try to repair it. Thank you.

    Why are there two inputs mosfets?
    by mikay786
    Just trying to fix this old Alienware m14x laptop.

    found a shorted capacitor and a shorted mosfet on the input mosfet pair.

    im i newish to this and was wondering why you almost always have a pair of identical mosfets on in the input? They both do the same thing so what the point?

    also on a side note i am eager to test laptop since no short now, is there a way to bypass the 2nd mosfet for a temporary solution until replacement arrives?...

    Macbook pro 13 A1708 Low voltage on bios chip
    by Marek011
    Hi, While trying to unsolder the BIOS chip, I accidentally blew out the R6130 capacitor and now I'm wondering what kind of capacitor it is because I don't know which one to buy. Getting to the point. The Mac draws 20v and 0.330A and does not turn on, it is dead. On pin 8 of the BIOS chip (U6100), the meter shows only 1v and then drops to 0v. After connecting the USB tester to the board itself (with all ribbons disconnected), the board consumes 5V and 0.024A

    Where could the problem be?​

    HP probook 4510s mosfet issue
    by Cuboy
    Hello,

    I am currently trying to help a ONG by volunteering to help repair laptops, it's something that i have been into since 2017, always watching videos, on discords, forums etc...

    I have an HP ProBook 4510s laptop that does not power on and has no indicator lights, which suggests an issue with the power supply or the motherboard.

    I started by verifying that there is voltage at the input of the motherboard, confirming that the power adapter is working correctly. However, when I checked the voltage at the output of the first MOSFET (Q1032), I found 19V at...

    Un50cu7000 2 blink oddity *partially solved
    by EazyBone
    I write this to maybe help another with this TV.

    So I aquired this TV a 2023 model. It started the 2 blink reboot problem which indicates bad panel. It was still under warranty and the repair man came by.

    The Samsung repairman brought a brand new panel and switched my original boards to the new panel. The new panel then had the 2 blink error code. The repair guy said he has seen this and the MAIN board on this model will cause the 2 blink. He then replaced the main/power board (they are both connected) and put it back onto my original panel. Voila it worked.
