Answer to "Why won’t my camera turn on?"Hi, Is there a display on the top panel or is that blank as well?
Answer to "The colors in my photos have been off by a couple shades?"Hi, You could try a quick settings reset by holding down the +/- exposure comp button on the top panel and the thumbnail button on the bottom left of the back panel at the same time for 10 seconds or so until the display resets back to normal. This will clear any odd settings back to the out of the box state. I have found a quick guide with images here http://seventrumpet.com/how-to-reset-nikon-d610-dslr-camera/ Simon
