    Why didn't you check for a short...lol. Check for short with and without LCD connected as 2informaticos suggested on BKLT output.

    820-3476 not recognizing SSD

    Check voltages on the SSD connector especially pins 1, 8, 24, and 47. You do not need an SSD plugged in to measure.

    iMac video card

    It's an old iMac that probably is not worth wasting time on...unless you can source a reliable card like 2informaticos suggested, it's going to be a waste of time.

    820-3332 Display issues....

    RAM, VRAM, GPU, CPU or broken internal trace. Going to be a waste of time tbh

    820-00850 No video. Boots normally

    If this is anything like the years previous, 50 volts went to the CPU and this can rest in peace...

    820-00840 - No PPBUS

    Figure out why no PP3v3_G3H first is it shorted to ground? Just fair warning, these ALWAYS end in dead CPU at some point, so it could have a faulty CPU as well or a CPU that fails weeks after you fix it.

    820 3330

    Double check that measurement. If it's 17 volts, then Q7030 is shorted. Replace the ISL6259, Q7030, Q7035, and Q7055 at the same time and see what results it yields.
