HP ProBook 4520s no display

[stuk0v]

Hello guys,
Laptop powers on (lights and fans) but got absolutely nothing on the LED screen.
An external monitor plugged to the VGA port doesn't show anything either.
Does that make it 100% a board/GPU issue? or is it possible that the display is not switching to external automatically?

Reason I am asking is I am very tempted to buy a replacement board or screen to replace it since the laptop cost me 0$ and is still an i7, but I wonder which would give me a better chance.

if you are not getting an picture on an external monitor, then it's about a 99% chance it's a failed GPU issue.

Thanks, considering I could find a *possibly* matching system board on eBay for around 75$, should I bother trying that?
I did not pay the laptop so it would not hurt too much.

Certainly up to you. I have many customers that would pay for the repair, and several others who would just buy a replacement laptop for a bit more. if you feel you can swap the board, then why not?

Thanks! I think I will give it a try. I like to do some tinkering from time to time.
