Problem with screen, anyone can help ? topic

Hi, at early sorry for my bad English, i'm from Poland.

Yesterday i wrote on Polish forum for Android thread about my problem with screen and unfortunately they cant help me, so i must write on XDA :) I'm mad :/

So, 2 days ago i saw on my screen vertical stripes on black/brown colour on screen. Small defect but im angry becouse this phone cost 400 Euro... This stripes are a shade lighter than the color on the screen. Saw only on dark colours, on bright colors all it's good so i dont know what is with this..

Anyone can help me ?? I can of course do photo.

Thank all and again sorry for my english :)
