No BS: My modi DAC wouldn’t power on, turns out one of the solder joints failed. Reflowing this joint fixed it.
With BS: My Modi DAC failed to power on one day and I had tried a number of different tests to see what it was. I tried a different wall wart (AKA plug) to see if it was the plug that failed. I tried a number of different connections (USB vs. Optical) to see if it was the input that was faulty. I had a look at the board to see if I could identify any faulty components – I was expecting a failed capacitor.
The closest I could see was a bit of a naff soldering joint on the large resistor. Figured I would re-flow the joint to see if that made any difference (what did I have to lose?). And hey-presto it worked.
