I’ve just replaced my TV tuner as the splash screen stuck and a bypass lead revealed it to the the unit.
In my haste to remove the old unit I couldn’t remember whether there was a plug to the green port on the back. I fitted the new one and tried it. No picture, only sound.

I took it all out again to see if there was a cable that I’d missed but I can’t see one anywhere. I’ve put my hand down the back of the loom and fished around and there’s nothing.

Is there a cable supposed to be plugged in there? That’s the only thing I can think of that’s stopping the picture from coming on (green port in the photo)
