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
