Random blinking pixels and flashes on a LED Cinema Display. What should I do?

Hello people. Yesterday I bought a refurbished 27" LED Cinema Display. When I connected it to my MacBook Pro some pixel starts to blink all around the screen. Pixels are coloured red, green and blue. I connected it to a MacBook Air and it worked perfecly.


I even shot a video: http://www.youtube.com/watch?v=Axdc-YeW8wI
