I've been happily playing with my $300 used D5100 for a week or so now. Everything seemed just fine ...apart from the way its output blows my D2X away! 8>/
Anyway, today I noticed a fine green vertical line, from top to bottom of the LCD display, about 12mm from the right side. It's always there now, whenever the screen is powered up, over-writing whatever mode the display is in.
Kind of a bummer 8>/
Has anyone seen or heard of this fault? Any suggestions?
