I have a Dell Inspiron 15-7537 with a touch screen. the entire screen shows tiny dots (for lack of technical term). Connecting an external display works and looks perfect so I know its not the video card. The dots show on boot up too. I can press to the left of the dell logo on the screen and it gets a little better. Im thinking maybe its a bad cable or loose cable at the inverter (given that the inverter is behind the dell logo). I can't find anywhere on the net where it explains how to disassemble just the lcd screen or if its even possible. It doesn't have a plastic bezel like many windows pcs. the screen assembly looks more like whats on a macbook pro. anyone know
1. what may cause these dots and how to fix it? or
2. how to get in to just replace the touchscreen digitalized or lcd inverter?
thanks.
