help! my "solarize" filter doesn't work

i use the Type tool in PS ,input few words, and rasterize the type layer, then run filter"stylize->solarize", but nothing happened ,why?

NM

no, i didn't do Ctrl+i

i just created a new document, typed words on it, and do solarize, found didn't work

does it work for stuff other than typography?

You have to have some different elements to the type. If it is just a solid color, it will go black. Try pasting a photo or adding a texture to the type. Then re-rasterize it and then solarize, there you will get your effect... But it wont work if its a solid color of type.
