hello everyone. the screen on my thinkpad is giving me these verticle and horizontal lines. they are multicolored and change depending on what is going on (whether it boots by itself or if it is connected to an external monitor). I have checked it with an external monitor and the computer seems to work perfectly. Seeing as the display changes, and there are multiple colors, i dont think it is the actual LCD. if anyone has any advice on how to fix this, it would be greatly appreciated. thanks to everyone for looking.
