iPod Nano (6G) Screen White on Wake

Hello all,

I have a 6G iPod Nano that I currently use as my primary watch. A week or so ago I started to experience a blank white screen when I press the "sleep/wake" button instead of the watch face (I have it set to wake from sleep to display the clock). When I hard reset it, it will come back fine and the screen will respond and work as normal, as soon as I manually put it to sleep by pressing the "sleep/wake" button and then try to wake it the same thing happens and I have a blank white screen that doesn't respond to touch gestures or anything.

What I have tried so far to no avail:

1. Numerous hard restarts (holding the "sleep/wake" button with the volume - button).
2. Tried this: iPod nano (6th generation): Hardware troubleshooting
3. Changed the watch face to display.
4. Recharged the device overnight (without full discharge).

Since none of this works I'm out of ideas. Eventhough I have a 6G Nano it should no longer be under warranty since I was sent it as a replacement for a different (older) product.

Any ideas? Is this a known problem? Thanks in advance for any insight any of you could provide. Also, what time is it??

Regards,
