Hello.
My laptop screen lights up on bootup, but doesn't display a single thing. So I went ahead and ordered a replacement screen, once replaced, I tried booting it up and guess what? Same thing. After a couple of reboots the screen went all pink pixels lines and weird stuff like that and then displayed "no boot disk" this was because I removed the HDD. After putting it all back together thinking that error message was a sign it was working, it still did the exact same thing as the old screen, Brights up, no display.
Could this be the internal graphics?
Thanks

Side Notes:
Attempted different RAM ( still no luck )
The screen has an integrated Inverter so that can't be the issue.
Sony Vaio PCG-71212M
External monitor not displaying either
