System structure: HDMI connects to the ADV7613 to drive the LCD directly.
HDMI Source ----> ADV7613 ----> LCD
When injecting electrostatics into the system, LCD images become white noise(As shown in the following figure)
But if disconnect the DDC(I2C) between HDMI source and ADV7613, LCD images are normal when electrostatics injecting.
1, How to make the ADV7613 output a white noise image
2, Why disconnecting the DDC affects the image output of the ADV7613
Thank you so much
