its the old video mod and it only works on most tv/lcd screens

try doing the new mod video i never did the new one but im pretty sure it works on all screens

but first try it on an older tv with av input...i did the old video mod and hooked it up to a vcr and it didnt work all i got was black

ok everything looks good and the board your using pretty much looks like the one being used as an example on the benheck forums

Do you have the video mod wired up like this?

And are you getting any picture at all?
