What happen with my 3.2" TFT?

I got a problem with the 3.2" TFT. I connect the TFT module with Arduino MEGA 2560. Then I followed the instruction from http://forum.arduino.cc/index.php?topic=101029.0, downloaded UTFT library, used UTFT_demo 320x240 and changed the display model to SSD1289. It can show the demo, but with many thin white lines. The lines moves when the image moves.

I have checked the wiring and it still happens. Any one knows why is that? Thanks for the help.

I’ve just changed the power

I’ve just changed the power source via power jack instead and it works perfect! So I guess it should be some problems related to usb cable/socket.

Thanks again for your help. :slight_smile:
