Laptop Screen Issue

My laptop screen has been acting up for a month now. I replaced my laptop screen 6 or so months ago due to it being broke and everything was ok up until about a month ago. When I started up my computer today there were 2 vertical green lines on the screen. Sometimes there are green or pink specks on most of the screen. When the screen arrived and was installed it had a small green dot on the top left hand side (not sure if this is relevant or not). I have an Acer Aspire One D255 and was bought around December of 2010 or 2011 I can't exactly remember which year. Any help would be greatly appreciated. I really can't afford to take it to a computer repair shop right now because I'm going to have to bring my car into a repair shop because of issues with both front doors and the left blinker light. I think it's the screen going bad but not sure. I got it off of eBay and this is the screen I ordered: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130708907314&ssPageName=ADME:X:RTQ:US:1123
