Screen Freeze

[coggerwayne]

Hello Corey and Bill
Still waiting from last Friday for info on solving problem with my screen freeze up after displaying "Hex Code" ... will not continue on to next screen.
Problem started during cold weather in which screen contrast changed but not sure if that was caused by me pushing to many buttons as could not read screen.
Still currently hard to read screen.
Let me know if you have any ideas.

Anyone else have seen this??
