Bottom half of screen disappears - appears when pressure is applied
Had the laptop for a few years now - Now the bottom half of the screen completely disappears and just shows random vertical dark hue lines. If i put a little pressure on the bottom left of the screen with a finger, it goes back to normal - once pressure is releases - it goes back to garbled lines. - Is this simply a screen connection - or is the screen fried?
any advice is much appreciated! (before i take it in for $$$$$)
Update
Follow up question for model S/N ending yx63 with same problem. Screen on initial start up (before logo appears) often has non responsive lower half that flickers from responsive to multi-hued mess that can often but not always cured by pressure on various places on left of screen. At times screen may work for a few days with no problems as long as it is not moved. When screen is shared with my iMac it does not show the distortions.
Can I confirm problem is LVDS cable not the screen without installing new cable?
Does the fact that the screen picture from the MacPro shows up clearly on iMac preclude the problem being caused by GPU failure?
