I have used DVI to HDMI cable to replace my former successful design using DVI cable for transferring TMDS signal to panel.

But the problem right now is the whole system stopped working, there no signal coming in from HDMI connector.

Do you have any ideas where is wrong about this DVI to HDMI cable?

I have checked the cable the connections are good.

Thanks in advance.
 

1. impedance missmatch
2. Broken cable
3. Broken DVI driver
4. power noise on DVI codec pll pins.
and etc..
