    Monitor Audio RSW12 - Green light, but no sound
    by MOSSEP
    Hi

    Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

    Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

    The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

    I have already tried replacing all of the...

    820-2610-A Sys onewire help, no green light. Please help from the gurus
    by lcdcaps1
    Hi

    I have an 820-2610-A motherboard that has no green light.
    I have noticed is when I do a SMC reset the light on the Magsafe blinks.
    From My understanding, the sys onewire circuit is responsible for the green light on the magsafe
    The sys onewire circuit on this model and others is more involved
    I was hoping if anyone knows about this and how it works, can reply and let me know
    I know this is an old model but I am sure there are people who still works on these or knows about them

    I get 1.1v on the C7771 capacitor and will replace...

    Macbook air 820 - 00165 fan spin, PPVCC_S0_CPU present, No green Light, No Chime
    by xalapamac
    Hello, greetings everyone. I NEED YOUR HELP

    I got this macbook that doesn't turn on, I don´t have a green light, but it's got a fan spin for a few minutes and after it's off.

    This macbook comes in without damage from liquid spill.

    The story of the Mac is that the screen closes and left without use for two days. Then they try to turn on and it won't turn on. Then they connect the charger and it doesn't give light.

    It´s a Macbook Air 2017

    Please help me understand how this works... Correct me if I'm wrong in my way of...
