My Asus G750JS laptop was heating up a lot after 3 years of usage, so I disassembled, cleaned the fans, CPU, GPU and repasted both of them. After I reassembled, the screen won't turn on. It was working perfectly fine before the disassembly. I had even overclocked it to 95hz (from 60hz). Things I have done :

* Connect the laptop to an external monitor through VGA (it works, GPUs are fine)
* Hold the power button for 2 minutes to discharge then plug to AC and power up
* Disassemble the laptop and unplug/plug the connector several times
* Blow the connector with a duster and then try
* Clean the connector with rubber eraser and alcohol and then try
* Weird thing - when I unplug the connector and try to boot with only the external monitor connected, the external monitor doesn't work.
* When I close the lid the laptop DOES go to sleep.
* I've checked the device manager and the monitor is there. Both monitors are named Generic PnP Monitor
 
Sounds like the connection to the attached display is either loose, or not functioning correctly. If it bent, pinched, etc., the cable can cause this to happen. Try disconnecting the cable at both ends, then reconnecting them. Make sure it is not bent, pinched, etc., and then try running it again. If that doesn't resolve it, you may need a new cable, or the display could be the issue.

Also, the fact that it won't show on an external monitor when the attached display is disconnected is totally normal. :)
