check the video chip..heat the video chip carefully, use the flux paste, this operation is trial ... if everything is ok you will have to do reballing ..

before you do the suggestion of peste.. try this if the system boots and have a display in the external monitor press F8 to switch to onboard lcd panel..if it displays.. try to reflash your bios with latest bios dump.. if no display using the external monitor try to go to device manager and click the display adapter look for exclamation point. if you see it.. video chip is toasted. if not.. if you can substitute a known compatible working lcd panel try that.. if not.. try the suggestion of peste..

lcd panel.ok
bios.ok
integrated graphics and processor
I heated it up a little bit but it may have deteriorated from the same overheating

using external monitor go to device manage have you seen dual gpu? maybe one of it fails..no exclamation?

or try to uninstall the video driver use only the basic driver and restart..
