I'll try these 2 sites.  I bought a new cable & the same wierd color comes & goes! Looks like a color negative to me as colors reversed. The normal color stays say for 10 mins. then so many mins. of wierd then back to normal again, odd! The old cable took nearly a year for this to happen but does not alternate the new immediately. I have bought a dear one on Ebay but I'm having to get my daughter to send it soon. I have a feeling it is a communication problem in my computer as it is a new problem & only happened since cleaning it when I lost tabs whatever they are!
