I have a Toshiba Satellite x200-21k (http://www.toshiba.eu/discontinued-products/satellite-x200-21k/) [ it has dual 8600M gt graphics card ]
I've successfully installed niresh osx mavericks and every thing was working well except WiFi. I was happy with this, and Niresh, you are awesome! Thanks bro !
But yesterday I plugged in an HDMI cable to my lap and the display went black, I was expecting to see the contents on TV, it didn't. So I removed the cable, display did not respond. Now I hold power button and shutdown.
Later I turned ON, now it doesn't even boot, no Toshiba logo or boot logo, simply a BLACK DISPLAY.
I've been 'googling' about the issue but found no solution.I thought of taking a video of the situation and luckily I found this video (http://www.youtube.com/watch?v=wLNJb5kxWhA), which best describes my issue.
Please help me !!
