No, not cables. All quite short really. Or connectors. When I tried it on another computer the problem was still there and this sort of confirmed that the problem was the screen.
As a 17" TFT I think it is one of the best available for the price but..........as with all these things they don't last forever but you expect them to oustay the warranty period - in this case it is 3 years with yet 20 months to run.
