Thanks for your guide! Is it possible to make a guide to replace the LED IPS screen from the N551JQ? Mine is black after a crash.

I think this is not very difficult, mostly you can simply pull off the plastic frame that is over your LCD (be carefull with pulling off!). You can pull it off with your fingers starting inside.

(Plastic frame can damage, but they are not expensive).

Then remove some screws, LCD will release, but it is still connected with some cables on the backside.

Try it and make pictures, so you can create a guide :).

Thanks for the guide! Sadly after doing this I found that my right side I/O (audio out and 1x usb port) no longer works. Any suggestions as to what could be the cause and how to solve this?

I'm pretty sure I have done everything by the book so I'm really bashing my head against the wall right now, I've never had this occur when replacing thermal paste before.

Thanks for your help

Maybe you released/loosened its connector or you damaged the board?

It was indeed a ribbon cable which had come loose (luckily no mobo damage). Something that I noticed is that the factory thermal paste had been applied all over the vram chips, as well as on those chips labeled “R36” directly “south” of the gpu die. I have the JW version of this laptop, which has some thin rectangular metal plates attached to the heatpipes, so as to cover the vram chips and others surrounding the gpu die. I found that kinda strange, seeing that the JQ version does not have this at all.
