Respuesta a "Screen cracked, where can I purchase another one?"if it's broken, you are better off getting a new TV. The panel will run about $300-400.
Respuesta a "LED broken screen , can I buy a LCD screen?"My wife has the exact same model. She broke it and after doing some digging I found the site linked below. Purchased it from them and received it within 2 days. When I got it in the mail it was B133EW07 V.2. I think it's suppose to be one of the better screens. Popped it in and it was working beautifully. Great Screen. Bright colors. http://www.humptydumptyservice.com/apple-macbook-13-unibody-a1342-replacement-screen.html
