Screen with dots (green, purple, blue)

[carlosm2]

Hello everyone, I have a problem with my notebook, a few days ago the screen started to show green dots instead of darker colors, and purple in lighter colors. I've connected the laptop to an external monitor and the image shows perfect. Graphical drivers are up to date. Sometimes, all dots disappear but after several minutes or hours they show up again.

Please help me to find a solution. Thanks.

Thanks for your answer KNRK.

But don't you think that it could be the graphic card? Is there any way to know if the problem comes from the screen, the flex or the graphic card?

As KNRK mentioned, it will be a hardware issue.

Have you connected it to a EXTERNAL monitor to see if the problem replicates? If it does not replicate, then it is your SCREEN/DISPLAY.

If it REPLICATES, then it is your mainboard.
