Chosen Solution
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
- what may cause these dots and how to fix it? or
- how to get in to just replace the touchscreen digitalized or lcd inverter? thanks.
tech4eleven the dots from your description are most likely stuck pixels. there is not really a repair for it, so you’ll be looking at a new LCD. Check to see if this video will help you.
