    The fan speed and filter reset solder joints look like that, not sure if that is ok. How do I check for cracked solder joints? Magnifying glass?

    How do I test the yellow rectangular caps on the board? I will say the ion function never worked when I had it working, there's an led for it and an ionization element but it never lit up when pushed.

    I have an oreck air95 purifier. It quit on me a couple years ago, my other one broke yesterday which is a similar model so I decided to troubleshoot this one. Neither turn on at all.

    Mitsubishi M VR700 no audio output

    OK I tried testing that with the speaker and I didn't get any sound, I tried on both coils. I am not sure if I checked the ground in the correct spot but I tried in a few spots where that resistor is. I hear a click on the board when I remove the headphones but thats it.
