I have found a solution for when my Tempotec iDSD Plus gets the Orange LED.
The solution is fairly easy. I believe that something may not be making good contact with the printed circuit board and may be preventing the DAC from working. However, slightly pushing around the SmartAction SA2000 chip, it seems to make the LED change back to green and allow the unit to work.
You can see the video below where you can see the fix in action:
To put it back in the case, I put a small piece of paper to make a bit of pressure around the SA2000 chip and so far, I haven’t yet had the orange LED issue again.
I hope that it keeps working fine, because I really enjoy the sound this DAC produces.
