This is very intrusive and risky repair, there are a number of much more likely candidates causing this issue (such as RAM needing to be reseated or replaced) that doesn't require complete disassembly. Complete disassembly should be the last resort.
Once you heat up the video core, it melts the solder joints back to the motherboard creating continuity. After a while with curtain types of motherboards heat is the biggest enemy.

I don't understand why you needed to take out cpu and memory card to do what you did.

you can also cancel the external vga card and activate the internal
intel chips card 😊
Can you please explain why this works?

@@doctorsoftechnology3457 then, why does this repair last for a short time as pointed out in comments somewhere on your channel? Just curious.
@@vasantkotkar9916 On some boards its a common issue with heat. The chip will lose continuity with the board losing video.
Pro tip Doctor, Clean the thermal paste off first before you heat it up... Dork!
Doggy, as stated in the video "make sure the core is clean of any residue before the reflow" 4:05
