I have an acer travelmate c110 the screen display problems

travelmatec110 screen will get diagonal lines in it then go black, can sometimes bring it back by pressing down on sreen or adjusting angle of screen. A)what is causing this? B) can it be repaired? C) what is needed to repair it?

If pressing on the screen fixes a laptop monitor, it's likely a connection problem between the computer and the monitor. What is needed to repair it will either be a trip to a qualified repair shop or a hammer.
