SMACKING my laptop display fixes it??

So, a few days back I go to turn on my laptop and the display is remained black. I tried [many] hard resets, connecting to an external monitor, and re-seating the memory. "Must be my graphics card nooooo" I think. Later that night I give it one last attempt before I take the dive and buy another laptop. I smacked it around in minor frustration, hoping maybe it might do something. And, by some miracle, it worked! It went back on!

Since then, I've done the smacking routine twice and it's worked both times. The latest time the screen was not completely black but rather had thin lines as well (black screen, with 10ish thing white lines).

I don't trust this will work forever, how can I fix this? Can I test anything while screen is still working?

Thank you.

Oh I thought the external monitor worked from the way that was worded. That's a bit more interesting now. Not likely to be the ribbon. I'd open it up and just look around the GPU area and see if anything looks loose/amiss

I'd say the ribbon that connects the monitor is probably either loosely connected on one end or the other, or is partially torn. If under warranty get it worked on if not eventually it'll tear too much and cease to work ever again or just completely unplug. Could be something else but those are the most likely two choices.

If the ribbon is loose, wouldn't it still work on an external monitor though?

If that's not the case, it is not under warranty unfortunately (just over 2 years old). Is this a fix that I could do by replacing the ribbon connector?
