Electrocraft Colouriser

I just got this colouriser (or more commonly known colourizer or even colorizer ) for 99p. It gives some pretty dramatic effects but the image is giving me and un-synced scrolling effect. It also puts out some cool patterns on its own. I need to work out all the ins and outs because it requires a reference signal (possibly pure sync as I tried outputs from my mixer) the insides are very neatly wired and all the pots are on a separate board perfect for bending! It is however mains powered so Im going to have to be careful. Cool piece but because of the difficulty of use I wouldn't pay over £10 if you see one.
