Chimes when it boots up to a BLACK SCREEN. Fails the flashlight test!

So i finally decided to upgrade my Macbook Pro (mid-12’) A1278. Got some awesome deals on black friday and replaced both SSD’s and RAM. While performing the surgical operation I decided to tighten my loose screen hinges because why not. Somewhere along the lines something must’ve happened because when i pieced it all together I booted it up. The beautiful chime came on but nothing followed on screen. Imediately thought I left something unplugged. Opened it back up and nada! Tried resetting the SMC and NVRAM as recommended by Google. Again nothing! Did the flashlight test and nothing comes up. My guess is that something shorted along the process. Any suggestions of what it might be?

Remove the new RAM putting back the original and swap out your SSD for the original HDD.
