In case Smilies added to the content or comment text do not work on your WordPress blog installation, here is the troubleshooting checklist:
1) Check if the Smilies are disabled on your site
In most of the cases, the ‘Smilies’ feature is disabled thru the settings. Check if that is the issue for you.
2) Check if the smiley image exists in folder
The images for the smilies are present inย /wp-includes/images/smilies directory of your WordPress root installation. The file names are like icon_smile.gif, icon_cry.gif and so on. Just check if these images for the respective emoticon exist in the folder.
If not, just upload the images to this folder.

3) Check in case you are entering the Smiley text in wrong manner
You should type a space before and after your smiley text. Otherwise the WordPress formatter will think that it is a normal text within the content and will not convert it to image while displaying on front-end ๐
