I have it happen occasionally, everything in the background runs fine, sometimes putting laptop to sleep and back on fixes it, then the screen vibrates for a moment(not sure how to describe it) and then works normally.

 
Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

I don't have any monitors to connect, but I did open this laptop some time ago, maybe didn't connect the screen cable properly as you say.

It happens rarely but makes me wonder if the laptop is about to die, it survived 5 years of heavy usage so far.
 
It can't hurt to test the cable (on both ends) to be sure it isn't that. Alas, without a monitor there is no way to really check if it is the display itself or not. Perhaps you could borrow one to test with? Just a suggestion.
