We are using IC ADV7513 HDMI Transmitter in our application. We found that ADV7513 is not giving DVI output in one PCB. It is observed that the resistance between Pin 18 (TXC+) and board GND is 73 ohms and also signal level at Pin 18 (TXC+) is only 1.65 V
whereas all remaining differential TMDS output signals are showing resistance open with respect to GND and voltage level is 3.0 V which is same as working board. The inputs to the board are available as per the requirement.
Kindly suggest why Pin 18 (TXC+) to board GND is showing less resistance?
