Problem with preview on Nikon D300

<p>I have searched for posts that would refer to issue like what I am having with my D300, but could not find any. So I decided to ask.<br /> I have been using my D300 for about four years with no problems.<br /> And recently while previewing photos on the back screen I am having this strange issue, where files are showing grayed out and showing just outlines of subjects from the photo viewed.<br /> Below is picture showing view of 3 thumbnails, but it happens to show me files this way while on 1 thumbnail preview or histogram preview. And just to be more clear- the same file will show fine on full screen preview and than change to this grayish view while on instagram or multi-thumbnail view. <br />Link to photo: https://twitter.com/JoannasFoto/status/280759259011092480/photo/1 <br /> <img src="https://twitter.com/JoannasFoto/status/280759259011092480/photo/1" alt="" /><br /> Here is link to a video showing how it looks like while scrolling through images: http://youtu.be/5PPyKr79gsI <br /> At first I thought it was card issue, so I have formatted my card, than used different one. I've changed batteries. Used various lenses. My firmware is up to date wccording to what's posted on Nikon's site.<br /> Not sure what else could be done on my end?<br /> I will truly appreciate if anyone had seen something like this and knows maybe what this problem may mean? I can always try to have it looked at by Nikon's service, but was hoping to get opinion from someone who dealt with something like that.</p>

<p>I've never seen this. Have you tried a reset (green buttons) of the camera?</p>

<p>I do notice that you have the highlight display turned on. What happens when you turn it off?</p>

<p>Thank you Charles and Matt. Unfortunately none of your suggestions worked :( </p>

 

<p>The actual images, once downloaded, are perfectly normal? It's only the back-screen preview function that's messed up? Does LV work OK?</p>

<p>If a hard-reset doesn't fix this, it's off to Nikon I fear, as something is definitely 'messed-up' inside...:-(</p>

<p>The only time I've seen pictures look that way is when I'm doing some manipulation in PS and have converted it to Lab color and am looking at a single channel. Very weird!</p>

<p>Mike, images are fine when downloaded. LV works fine as well. <br>

The more I am thinking about it, the more I feel that it might be a firmware issue- in creating thumbnail previews.<br />And cannot stop wondering whether going back to older version of firmware may be help...? <br /><br /></p>

<p>going back to older firmware may not be possible.</p>

<p>Of course it won't. If this were a firmware issue, lots of people would have complained about that version of the firmware.</p>

Thank you all for your responses.

Yes, I guess my thoughts about firmware might not be the correct direction. I am getting the camera ready to ship to

Nikon's repair service, since none of my actions (resets etc.) works.
