Problem with my DSD-1 display screen

I don’t remember my screen flickering before, but lately it has been constantly flickering when the DAC is playing. The flicker is at a constant rate - about 2 to 3 times per second. It cycles from 100% illuminated, down to about 50%, and then back to 100%. This seems to be new.
I tried turning the DSD off, in the back, and then re-initializing, but the flickering persists.
Has anybody else experienced this? Do I have a big problem, small problem, no problem?
If I need service, do I send the DSD-1 to PS Audio, or is this easy-peasy and I just get the parts and have my tech here do the switch?
If there is a thread here about this problem could someone point me toward it? I searched and didn’t find anything.
