My iPod touch does not respond since yesterday. I cannot see anything on the screen and the buttons don't do anything, no backlighting either. The problem started when I wanted to plug my iPod into the wall to charge it (it was almost empty). When I plugged in my iPod, the screen went out and I have had no response since. I think the battery is broken, but I am not sure. How can I fix this? Or should I contact Apple?
It sounds like there a good possibility of it being a hardware issue, in which case you should contact Apple.
If you haven't already, about the only thing to do, is plug it into your computer for about 15 minutes. Sometimes it takes awhile, if the battery is completely dead, to get the charge started. But, I'm pretty confident that won't work, considering it had life before you plugged it in. It would be something to try if you wanted to take the time.
