Rare Half Dead Player

[wirklich]

I have a nano clone 1GB and I forgot that it was "ON" for a few days. When I found it I switched it OFF and then ON again and nothing happened, it didn't turned ON......I thought......"well, I guess the battery is low" and I plugged it to my computer to charge it . My computer recognized it as usual, but the device screen was blue !! .. Ok I thought " its a Firmware problem then (I changed my firmware just modifying the original one and I never had a problem)" .... so I used the update tool to reload the original firmware on my nano clone but didn't work....the screen still being blue. I plugged the earphones and my surprise was that it still plays my mp3's !!......just the screen is blue. Does anyone have had the same problem ?? I'm very confused....I'm checking if theres some sort of problem with the screen.....I've never dropped ...:S
