It's only about a month old, but later that night the two lines went away and haven't returned yet. I'll keep an eye on it, but it's been running great since.

I just installed my MX630 and noticed that on both line 1 and 2 (on the same verticle line) a : and | are constantly displayed. Clearing the display does not clear these two characters. Any help would be appreciated.
