I checked for bad soldered and everything is corectly with the boards . Please tell me how can i slove this problem what should i do more ? Thank you soo much

Have you tried it on an regular tv ( tube screen )? Some computer tvs ( the newest models ) do not show correctly. Like mine computer-tv will not show right away. So try another tv or display before experimenting with it.

I tested on that kind of TV too but its the same dont work on AV ports only black screen . On RF Switch port with RF cable everything is fine but not on AV
