Blank screen after reassembling my predator helios 300 (G3-57177)

Today I opened my laptop (2017 model)for cleaning dust. I took the heat sink off and put it back after cleaning it. I have done this multiple times in the past, but this time my laptop won't function anymore. 
When I press the power button, keyboard lights up, fans start, but there is absolutely no activity on the screen, not even the backlit. Then the fans stops but the keyboard remains lit. 
I have tried booting it without the HDD (OS is installed in SSD), reseating RAM, connecting charger(which is getting detected), but nothing works.
