The display window on my GE JVM1790SK01 is too dim to read it

In order to see the wording on the panel, I have to turn off the kitchen lights completely to even read the words. Very frustrating, but I’d like to find out if there is an easy fix before I remove it and throw in the dumpster. This model is ten years old and no longer in production. THANKS if anyone out there can help
