DS Screen up-side-down

Suddenly my DS screen image is up side down. I’ve turned the unit off and on several times with the switch at the back of the unit with no change.

You need to recalibrate the screen. Power of the dac with the rear switch. Hold the front panel switch in while switching the rear panel switch on. follow the prompts on the screen. This should get it to flip back to normal.

Thank you, that fixed it.

You are welcome. I knew this would fix it for you as I caused my screen to invert once when checking the calibration.
