Hi folks
I have a problem in a board I am developing.
We assembled two tfp410 to a dual stacked dvi connector. I am able to connect to a dvi monitor only from one of them .
The device is working without I2C (all the signals seem connected ok) and video data and clock are reaching both devices.
both devices are assembled in the same way - just copy/paste one of the other, they are just on opposite sides of the PCB.
I am noticing that in the "non-working" one, the TMDS signals seems slightly lower, and they do not seem to bear the same data.
Any ideas? I can attach the drawing if somebody is keen to help me
