We just went through this about a month ago with our 15 333MKS. Our screen went blank though just green. It still auto leveled and would return the coach to the unhitched height. After researching on here and the internet I tried the following which did not help the dreaded blank display: Unhook battery and wait a few minutes, hooked battery back up no change. Unplugged back of display waited a few minutes and plugged back in, no change.
At this point I got online and sent an inquiry into Lippert. The guy actually called me in a day or two and asked me to trace the harness wire up to the main board that's screwed into the ceiling of the storage bay and unplug it there. He said this worked most of the time. It didn't. We emailed back and forth a few times and he shipped be a new touch pad panel/base no charge. When I went to install the new panel I noticed the base was not flat once the screws were tightened down. This might have made the touch pad twist some which might have twisted the circuit board on the first one causing failure. Ours works now, I'll try it next weekend when we camp. Just remember you can manually raise & lower the rear stabilizers and front with a 5/16" socket.If you do remember to unplug at the jack first. Good luck!
