I just bought a TV Mini, which I hooked up to a 28" sony wega using the yellow,red white cables.
When I turned it on it asked me what type of connection was being used. I selected the yellow red white one, and the TV then ended up with a wobbly picture.
It’s not impossible to see the menu, and I can’t work out a way of resetting it. I’ve tried pressing the reset button for various periods of time to no avail.
The TV does not have another connection.
