Hoya!
Regarding the colour problem... Video cables are quite stiff and tend to get loose around their soldering...
So, while all is on, try to gently move the cable to see what happens... If nothing happens, it could be some looseness of the plug itself.
Well, that is what I guess anyway... :-P
BTW, I plugged my Amiga on a TV some months ago and, while the machine runs perfectly, the diplay was slightly purple...
