Laptop display is white

[Captain Sisko]

I'm flummoxed by this one

My mates HP Envy 17 kept going to a white screen during use and was chugging out hot air
So I have since dismantled, cleaned and put on new thermal paste
Now when I re-assembled it, the display was working but now it keeps going to a white screen when turned on

If i plug the laptop into an external monitor - the display is fine.

I dont think the graphics card is at fault but is it likely to be the screen or backlight or even the connector itself?

Just replace the screen.

You'll get one cheap enough on flebay.

Thanks Kingweed

I tried removing and re-inserting the cable but still the display was white so I have ordered a new cable and a screen since the bastard thing is in pieces!!

So the cable and screen came today.......and the screen stayed white

Just going to resort to remove the screen and have the "base" plugged into a monitor instead.
godammed laptop!!!
