I haven't had that problem but the day after I bought my Kobo, I turned it on and there were ghost images (even after a 1/2 hour) and a blank line running down the middle. It's a new product, there are bound to be bugs and defective products. Call kobo see what they say. I assumed you tried resetting it? Kobo will probably say to take it back. If you have been having a few problems with it, yeah I would take it back.
