HDMI Transmitter I2C Issue

Hello,

I have a general query regarding the HDMI transmitter.

Before connecting the HDMI connector to my board, the HDMI I2C lines are 5V. But once the HDMI connector is connected, the clock line voltage reduces to 3.3V and data line voltage reduces to 0V. And also the display is not turned on, even though it is detected in the code.

Is there any idea what could be the issue? Please let me know.

Thank you.
