TFT problem with Arduino

Hi I've got a problem with a LCD 3.2" and Arduino Uno.

I connected all in the usual way and I load a test program, but I've got a lot of interferences . Here, there is a video.

Could someone say me why happens that? How can I fix the problem?

Thanks in advanced

I found the problem: the wires!! If I mount a tft with wires, I get a lot of intereferences, but If I mount witht a arduino TFT shield, the interferences dissapear

Regards
