Why are there horizontal lines randomly showing up on my screen?
I bought my MBP back in 2012 and I haven't had any problems since. However, this past week has been really trouble some as it didn't want to turn on at all at the beginning of the week (this was fixed by unplugging and plugging back the battery connector).
Last night I was using my laptop and all of the sudden weird horizontal green lines appeared on my screen (photo 1) after I had carried it from one place to another. I had to press and hold the power button to restart the laptop as the computer was not responding to my finger on the trackpad.
Later on last night I was carrying it again and I noticed that when I held it on the left side (photo 2) the screen started doing that funky thing with the lines. So I restarted it again.
Now I am avoiding holding the laptop on that side, but anybody have any idea what is the problem and how can I fix it?
Please note that I do not have Apple Care.

I've tried resetting my PRAM as I did some extensive research regarding the matter...but it didn't seem to resolve the problem.
UPDATE: It seems as if it doesn't matter how I hold the laptop -- If I hold the laptop with a single hand on the left/middle the lines appear and it freezes my laptop... ALSO the lines done appear the same all the time but they are always horizontal...
i have a similar problem but it doesnt freeze when i hold my laptop a certain way. they seem to just show up and either go away on their own or I have to reposition the laptop to get the connection back with the display to make them disappear. it's only temporary (literally only a few minutes) and it comes back again. theyre just random tiny black horizontal lines, sometimes it's a lot sometimes it's only a few, but no one seems to have a definitive answer. i tried doing the whole PRAM reset but my laptop will literally just switch back and forth from gray to black and not turn on. so i turn it on normally and nothing changed. ive tried this several times. im guessing at this point it is a hardware issue but i want a second opinion before i call anybody. please help, this computer is so much money and i need it for my schooling. im on winter break so i have until then. thank you!
