I really haven't had the time to investigate the issue since I'm outta town til next weekend but i don't think anything is shot. The display still works on my remote so i that is why i have this is feeling.
I suspect the issue is related to corrosion or water somewhere in the wiring (most likely by the remote since this is exposed). If you have the time give everything a real good cleaning with a good electrical connections cleaner at both ends and see if the problem goes away.
