I have a MacBook Pro 13” Late 2011 that no longer displays video to its LCD. The screen is lit and white but nothing can be seen otherwise. I've connected an external monitor and it works well. I've taken the machine apart as I was also having problems with the WiFi reception. I was able to determine the problem with the WiFi was that the wires had become torn where there is factory stripping near what appears to be a grounding screw. All three of these wires were torn.
Could these three wires being separated be the cause of the video too?
