Hello,

I have ST7920, connected serial with arduino. All connections are perfect. 
There is no bad circuit.

I uploaded GraphicTest example to my arduino. It works well. But after several 
minutes it has garbage. Chinese characters etc.

I tested with Mega2560, UNO R3, DUE. Had same problem with all.

How can i fix this problem? Lcd faulty?
