Video card's are generally socketed on laptops short of say Intel's IGP, YMMV. Of
course no upgrades but you can with some luck find replacements (pulls) of same model
on ebay and various liqidators.
Depending on age of laptop it might be better to start from new or sometimes same
models less display can be had used, same as video cards.
When my c840 crapped out I simply bought a used unit and swapped over what was better
on mine. In fact I ended up buy a pulled mobo (when I found a deal) in the end &
giving the crapped unit to my GF to use.

Well, from my experiance working with laptops, if it powers on but
nothing comes to the screen, you can try changing the memory, but after
that it's either motherboard, video card (integrated into motherboard),
CPU (I put CPU *WAY* down the list) or heat related.
Assuming motherboard: Motherboard Replacement
Assuming videocard: Motherboard Replacement
Assuming Cooling: Verify fan is spinning properly and clean out
heatsink on CPU
Assuming CPU (Lowest chance): Can you really get a new Laptop CPU
that's worth the price of getting?
Generally it is heat related that causes failure. Check the caps on
motherboard, resolder new ones if that's the problem, other than that
it's always motherboard replacement.
