Chosen Solution
I restarted my macbook and just after the apple logo appeared there were some flickering lines on the screen and then just a row of vertical red lines. I turned it off and attempted to reboot it but now all that happens is the optical clicks and the front indicator light comes on. Otherwise it’s just a black screen, no boot tone. I attempted reseating the RAM, both slots, a PRAM, SMC reset, and manually removing the battery. I also booted it with no RAM in it and got the beep tones so I believe my logic board is alive.
Logic board has failed - based on the vertical lines and unable to boot. Check out the last paragraph of this page: https://www.apple.com/support/macbookpro… The late 2011 15" have known logic board issues and actually had a recall on them. Might be worth calling apple and seeing if they will replace it still even though they ended the program.
