M15x Display Issue

Hi all! About 3 weeks ago my m15x (P08G) started to get really hot while playing games. Most of the heat was coming from the CPU side of the board and it was red hot to the touch after about half an hour of game time (mostly WoW). So I decided to give the CPU and GPU vents and fans a clean out and apply a new layer of thermal compound. I went ahead and did that job making sure I kept everything static free. Turned back on the laptop and noticed the display wasn't working. Opened her back up to see if I did anything stupid along with unattaching and reattaching the display cable but I couldn't find anything wrong so I took out the cell battery for a few minutes, put it back in and then tried again but still nothing. Everything else is running fine. If I attach my TV to the VGA everything shows up and I can still play WoW without any problems which is why I don't suspect I messed up the 260m. I just can't for the life of me figure out why the display suddenly stopped working. One weird thing though is if I close the lid and open it again the display turns on but the screen stays completely blank. It is a weird issue. Has anyone had any similar problems or have any ideas how to correct this without having to buy a new HD display? Any help is appreciated.
