NS-39D400NA14 Video Issues

I recently acquired an  Insignia NS-39D400NA14 for use in part as a computer monitor.  There are two issues with the unit:


1)  A snowball size patch in the upper right quarter of the screen that is slightly darker than the rest of the picture - it's especially evident against solid color backgrounds.


2)  I edit a website that uses faint background grid lines to position objects on pages.  When I log into the site to edit, everything appears normal, but when I start to scroll down the page, the vertical grid lines nearly disappear - the horizontal lines remain unchanged.  I;ve had a number of other monitors on this system and none have exhibited this display issue.


Help?  Suggestions?
