Display black. Start chime works. Does not connect to external monitor

The display of my old workhorse is pitch black. It was dim 2 days ago and I could see a few things but now it has gone completely black. I tried connecting to an external monitor using VGA display but it does not connect. Someone suggested I clean the RAMs pins with a soft tissue which I did but that didn’t fix things. My universities tech support suggested that I replace the LCD display but why wouldn’t it connect to an external monitor even if the LCD is bust. What could be wrong?

Thanks,

Abhishek

To connect to external monitor you have to press “windows key “ +“p”

Multiple times until it connects

Thanks for your answer. It now connects to the external display. So clearly the display is broken. Is it possible to repair it or should I just go ahead and change it!

best,
