Dead or Stuck Pixels on iPod Nano

* DISCLAIMER - It appears long but it is still the same question; most of it is info in case you would like to try and answer

I have an iPod Nano 5th Generation and it has been working great until recently. One night I noticed a few dead or stuck pixels on its display but I thought I'd figure it out in the morning. When I woke up I noticed that not only had the group of pixels increased, but there were now two lines of pixels near the bottom and middle of the screen. It appears to have stopped spreading though

I'm not sure if they're dead or stuck, and how I would fix the problem but:

. When they are on a white background they are black, and when they're on a black or coloured background they are white

. I can also just make them out when the actual display is turned off

I believe it may have had something to do with me dropping the iPod ( it has a hard plastic case, but there is slight room for the iPod to shake around in the plastic case)

I'm also pretty sure I can't go to apple because it is an old device

Any help in fixing this problem would be greatly appreciated

- Thanks
