I have a week 36 16G Touch and have had trouble telling if I had a black screen issue. Jay Z helped a bit, but that photo seems like a hologram on any screen. My kid was watching the Pixar short film Lifted and it made it real easy to spot. in the first 30 seconds of the short there is a shot of a windmill in a field at night. The touch was very dark. I matched it up to the same shot on my imac and it was VERY clear I have a screen issue. The windmill almost looks like an x-ray compared to how it should appear. Just wanted to post in case anyone was having similar difficulty. Worth the $1.99 for the film as a test.
