HDMI 1.2 Tx detection issues on I2c bus

Make sure your address is not shifted by a bit.

Make sure you're connected to the correct I2C port, not the DDC port.  Not likely but it has happened before.

Make sure the voltage levels and speed are correct.

Other than that it should respond as a standard I2C interface and as outlined in the attached document.

Hi,

Thnks for the prompt reply.

We indeed have checked for the following above conditions but still HDMI detection on I2C bus is nt happening.

Cn u suggest any other alternatives in this matter.

I2C access is fairly straight forward unless the device is broken.  Here's a thread that has a list of various suggestions but I think you've covered most of this already
