What is your model #? Most of the time when I see this problem with customers sets is when the DMD Chip, thats the Digital Mirror Device Chip on the DMD board is faulty. Their is 264,000 thousand micro mirrors on the face of this chip and they are all on hinges, depending on the voltage applied + or - they tilt for each individual color. Which is Red Green and Blue. Replacing the DMD Board usually solves this problem. Or you can just change the entire optics engine assembly. This site will probably be able to give you a quote on a new optics engine assembly if needed.

The fields of stars shows up on the tv. Is this a big issue?


The white dots/stars you are seeing is a failing DMD board. It is the board with the million little mirrors on it. The white dots are mirrors stuck in the on position always reflecting the white light from the lamp. The DMD board is a technician replaceable item and part number varies by model code. Please contact a local servicer to have them look at your TV so they can order the right part number for your DMD board. Please take a moment to rate my answer. Thanks....

ACER 3680 2022 LCD SCREEN PROBLEMS


It may not be a problem with the lcd.

This is most likely a problem in the video card of the laptop.
but you can test it out, if you plugin a extra screen to the laptop to see if the white dots come to the other monitor aswell.

If you see white dots in both of the screens this means the video card is about to fail. and would need to be replaced.

If you don't see any white dots on the external screen then the problem is in the lcd.

You can call bestbuy they should give you another phone number to call for repairs / parts.

Gateway laptop vertical dotted lines across the screen


Sounds like a problem with the LCD assembly or cable. You may want to reseat the LCD cable at the LCD end. It could be a loose internal connector in the LCD assembly.
