[iPod nano 2g] Last 3 rows of the display are not visible/blank

[bobcat]

Hi,
I have a 2GB iPod nano 2g, and I tried installing RockBox 3.10 and 3.9.1. It is working great except the display. I cannot see the lower 3 lines of the screen.

The original Apple firmware works perfectly, and the Apple boot logo is also displayed correctly.

Also, the audio channels (R/L) are reversed.

Thanks
