HP laptop I'm told was originally worth $2000 will turn on and show the HP logo on the screen and then refuses to show anything else. What's wrong?

I got it used 8 years ago and has worked perfectly fine until a few months ago when it started doing this. Obviously, it can't be a dead light source, otherwise I wouldn't get the HP logo. However, when that DOES come on, it has a slight pink or orange tint to it instead of being all white. After the logo, the screen goes black and, rather than show the Windows boot-up screen (Enterprise), it just stays black and I can't get anything else up on the screen. I tried going to Safe Mode. I have no idea if it actually showed up because the screen won't work.
The only other issue I've had with it is that it gets overheated if I have it on for about 45:00 or so, even though I have it propped up at least 3" above the surface it's on so it can get as much ventilation as it possibly can.
