Bottem 2/3 of screen white or vertical lines

Hi, my 17" Macbbook Pro A1151 has a screen problem, the lower 2/3 of it is either white of has vertical lines. Also on the top 1/3 of the screen If I have windows open they give off purple lines going upwards.

I have disassembled the mac and the screen and check the cable, nothing I do to the cable changes anything, if I push on the LCD the entire screen goes white. Asking on here as I believe its the LCD its self that's gone but I cant be sure.

Also, at the moment I cant get an external display to work, but before I installed display drivers in bootcamp I was able to run of an external monitor easily.

I will upload some pics shortly.

Thanks for any help.

Hi, thanks for the help, an update on the mac, I eventually found that despite trying pressure on many parts of the screen and bezel previously to no effect, if I pinch the lower left corner of the screen on the LCD its self, it corrects the problem. It is now for all purposes fully functioning. After I pinch it there it works for longer then I can before needing to be pinched again.

I have looked into it and found that it is a connection in the screen its self so this should be resolved with a new LCD.

Regards,

Chris

You've probably encountered My MacBook Pro 17 freezes and lines in screen!. Only you can determine if it's worth the time and money to replace the logic board.
