I got an Orange Pi zero with expansion board and tried many images , the original ones, h3droid and armbian legacy...by the way, all the systems show the image in a looping on my tv(rolling from bottom to top). Is there something to fix it or any reason that can cause it?

Please. Anyone?

How to fix my tv out using expansion board av javk output to fit a ntsc tv?

There is very limited support and interest for TV out in general but IIRC guys at http://www.retrorangepi.org/ did some progress on this. Check.

Thank you for answering. So I can assume that just using retrorsnge I can have a decent video out in this board?

Actually, I am not sure but its the only alternative worth trying. For playing retro games, TV out might make sense despite its low quality. 

 

Also, do some search. I remember more topics regarding TV out but I didn't pay much attention.

When I tried to boot with a slow sd card I could realize no image but the board was on. So I though that using a better SD It could work fine. But no. Even using my San Disk ultra I still having the same behavior for any OS: armbian, h3droid, retrorange pi 3.0.1 or even the provided one at orange's page.

 

Please. If someone faced the same behavior. Share here any solutions is welcome.

 

Note: I don't know how to access it thought ssh too it seems to refuse connection.
