Has anyone ever had an issue with the Legacy Handset where the icons go all dark. When I initially startup the icons are present, but after a few minutes they go dark as if the contrast was turned up. The display is fine but all the icons buttons become black squares. They still function as I press them from memory. This has happened and when I turned off the system and came back the next day it was functioning normally for a little while then it starts up again. The contrast settings are all set to 50%.
Anyone ever have this happen and if so is there a fix?
