Mini Maxx Issue

my truck is ******d and has had the same mini maxx on it for a few years now. Just recently when I startup my truck the mini maxx beeps like normal when its powering up, but the screen stays blank. There is power to it and it is lit up, but its just white blank screen. its not causing any issue with the truck running or its performance. it just cannot read any of gauges or change any settings. Has anyone had any issues like this or know what is going on
