Parallax Serial 2 x 16 LCD display problem

Anyone know what would cause the 2 x 16 character backlit & the non-backlit lcd display modules to show black squares across the top row.· It does this regardless of if there is a signal from the processor or not.· I have put the module in test mode, and only applied 5v to it, and I get the black squares.· Any ideas?

    Did you try turning the contrast adjustment on the back?

    yeah, The contrast still works, but I am just getting the black squares which fade or darken. I thought I might have had a static problem, I was just wondering if anyone else has seen this kind of failure mode.
