Try putting it on google docs and viewing it in the browser.
I have been playing with my new 42LN5700 Smart TV and have just tried using a USB port. I plug my flash drive which was a jpg, doc, and a xls file. It asks me if I want to open and it goes into "smart share" which has photos, video, and music. I see the photo but not the other two files.
Is it possible to see a file on the usb drive which is not a photo, music, or video file??
