LCD problem after changing ssd - help to narrow down symptoms?

본문:

Hi there.

After following different tutorials here, I decided to upgrade my iMac 27" late 2013 with a new SSD. But, unfortunately, when mounted the display assembly back the image is scrambled - I can barely see anything.

* Backlight is good
* Connecting an external monitor shows the image properly
* Changed LVDS cable and shows the same thing. But, weirdly, after changing and reseating the cable once or twice, image appeared, and after a restart, disappeared again.
* Cleared PRAM, and all sort of stuff

I believe it might be the display assembly, but just wanted to ask if someone had this issue previously, just to make sure I don't buy a new display assembly and then figure later on the problem is the motherboard. Below is a picture of what I'm seeing:

Any thoughts?
