Laptop doesnt start, nothing displayed on screen

My screen broke, it leaked quite badly but I could still see bits of the page I'd been on. I turned the laptop off but when I turned it back on the screen was completely blank. I've replaced the screen with an identical model but still nothing. I took the case off to check connections and everything but can't see an obvious fault. When I turn it on the fan starts but then slowly comes to a stop. I've tried connecting to my TV but that doesn't show anything either. Anyone have any suggestions as to the problem?

Hi,

Try disconnecting the LCD screen flex cable from the motherboard end only and connecting the TV (I assume you are using the HDMI connection) to the laptop's HDMI output connection and see if you get a picture.

If not try the vga connection (I think it has a vga connection, maybe not, specs says it has) to an external monitor or to your TV if it has a vga input.

If either the HDMI or the vga works see if you can initially get into the BIOS screen to start with, just to prove that the video works properly. If it does, try booting into Windows and see if that works. If it does there may be something wrong with either the video flex cable or the new LCD screen.

If there is still no picture then there may be something wrong with the GPU.
