My screen goes out and comes back on perdically
The screen stops working perdically for no reason then later will come back on. It will turn blue with white and black lines. When I attach an external monitor everything works fine, but it is not convenient to have an external monitor hooked up all the time. The monitor will perdically start working normally again and I can't seem to figure out what is making it stop and start working again. Does the LCD screen need replaced.
Is this a good question?
