I apologize - I was wrong. It was not the video chip.
It is the WIFI-Module which sends the video to the phone/tablet.
Here are the steps I followed to fix the issue.

I really hope it helps. It worked perfectly for me when i could get video on the card, BUT video would NOT stream to my phone so I could see where I was going.
Best of luck!
