Solved! Cant boot ASUS k55a laptop shows black screen

[nshayan]

Hi,
I have a ASUS k55a laptop. I opened the back panel to check the existing RAM model as I wanted to add another RAM in order to improve the laptop performance. I reseated the RAM again and tried to start my laptop. But the power turns on and it shows no display a completely black screen. Please help me resolve the issue.

When you opened it up you may have jarred the cable that connects the display loose or have pinched said cable when you closed it back up.
