    Could you run a 3 phase motor using Arduino?
    by Donny2derby
    If you connected in the control wiring onto an inverter could an arduino programmer be used as the controller?

    In my (limited and attempting to learn mind) using the right set of code and some simple wiring this would be relatively simple to achieve??

    Yes?? Or if not can someone tell me why please 🙂

    Thanks 👍🏻

    Lg oled55b8 t-con question
    by reassor
    There is 2 sia ics and in 1 section where u see dots on the coils i have 2.2ohm there and there is no voltage on them at all.

    Also i read in other topić how psu works on these tvs and when u pług it in there is constant 40w draw from wall. When I unplug display from tcon it drops 10w when I unplug tcon it drops another 10w (unplug done w/o power ).

    I'm mostly sure its main board cpu cause no sygnał to turn on 24 volt for panel and its constant draw.

    For now I'm just curios about these w coils . Could not find any datasheet for ic thats the lines go...

    PS4 pro power supply coil whine
    by satouri abdellwahed
    [SIZE=12px]I have a PlayStation Pro that has a buzzing and ticking sound from the back on the side of the power supply. I searched for a solutions , i tried to make reflow for some of the components but it did not work. In addition, I used silicone on parts on board without any changement. I discovered that if I make a short on the IC in the left corner, the noise stops. Is that dangerous?[/SIZE]

    ThinkPad X270 (NM-B061) no POST
    by rumpumpel1
    I have a ThinkPad X270 (NM-B061) with the following error: the mainboard tries to start, the current goes up to 80 mA and then immediately drops back down to 20 mA. This is repeated every few seconds. Fortunately, there is a timing diagram at the end of the schematic. Starting from the top up to and including -PWRSW_EC it is all as shown in the diagram. Starting with -PCH_SLP_S4 you can see the periodic behavior, i.e. instead of the signal staying at 3.3V, it always drops back to 0. What conclusions can I draw from this behavior?

    Dell Vostro 3420 BIOS Password Removal
    by sammus540
    I have a Vostro 3420 8H8K5R3​-8FC8 that freeze at any attempt to enter bios password or the recovery master password received from dell. I do not have a clean BIOS image to flash.
    And as luck would have it happened a couple of months ago right outside of the warranty period (Dec 2023) warranty expired in September. Any help or guidance is appreciated.

    Lenovo Legion Y520-15IKBM - No power besides the main rail
    by Fronczek
    Hello people,
    I've got this laptop not working for repairs, and as you can see something was done to it as you can see in the coils PL58XX (which I for some reason cannot find in the schematics...) The first FET (PQ201) was not an original part and a questionable one at that and the second one (PQ202) was shorted. Both are N-channel. Ordered replacements for them and replaced them after arrival. Now I have encountered another problem: there is no power at the second FET. By following the thread linked I got to the injection part. Applied 0.8V at 1.5A, but couldn't feel anything getting hot,...
