I want my old LG-e610 to kinda work again, it's display doesn't work at all but the touch screen still works. It has been like this since march of 2014.
Welcome to Android Central! You could try something like ScreenShare, but the problem is that you'd have to be able to see what's happening on the phone in order to install it and set it up. Things like DLNA, Miracast, or SlimPort compatibility are dependent on the hardware and/or firmware, and are not things you can simply install with an app.
