    Sony LED 65X9005A shuts down after few seconds - looking for help
    by tec3000
    Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

    I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...

    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,...

    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 👍🏻
