Cheap TV Parts 
Samsung PN51E440A2FXZA
We have this repair kit that has been taken out from a TV with a broken screen and tested to make sure that it's guaranteed to work. We advise that you check that part you need to make sure that you have no confusion with the part you really need. Make sure that your problem isn't the screen but make sure that it's the motherboard that you need.
