    Re: emerson 32" lc320em1

    I know this is an old thread, but for the record, I had a very similar problem. Backlights would flash on for a second then go off. It seemed like the Protect3 circuit was the problem. I hit Q1500 (2SK2417) on the inverter board, which I think initiates the protect circuit, with a hairdryer for a couple seconds and boom it lit up and stayed lit. I then hit Q1500 with cold air can and it shut down and wouldn't re-fire until I heated it back up again. The Zener Diode in that circuit is a very specific voltage (and kinda hard to find) it may be suspect as well but replacing Q1500 (and Q1550, 2SK2417 for good measure) indeed fixed it.

        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...

        HP Elitebook 850 G8 CAPS lock flashes 7 times and charging light always on
        by esqmooo
        Hi,
        I'm facing this issue since this morning. When I try to power it on, the CAPS lock light flashes 7 times (or 6 if not counting the first one when the power button is pressed). The charging light is always on as if the laptop was connected to the charger. The issues started gradually where it would flash the light but after trying multiple time it would power on. I tried to open it and I noticed one coil "1R0 2127" gets hot when the charger is connected. Note: the charging light directly comes on when the battery is connected or the charger is connected.

        MBP A1286 820-2915 green light only, no start
        by blazzelia
        Hi guys,

        I have this 2011 MBP - the company I was working for, bought it at the time for a project and gave it to me after that. Later on, I gave it to my daughter which used it for normal internet browsing and office apps. At some point the, now famous, AMD GPU issue hit this laptop as well. I disabled the use of the AMD GPU following some information I found at the time (the one that, at the end, one moved AMD kext drivers to a backup location). So the laptop was using the CPU graphics and it was ok for the said daily usage. I even replaced the drive with an SSD one and it was operating...
