Please Help me, Screen Problem after Replacing HDD with SSD
Hi,
I did it twice before, replacing faulty hard disks in two iMacs, everything went ok, this 3rd machine (only one normal 3TB HDD), i just swapped the HDD with SSD (Samsung 860 EVO) following the guide, with the frame and heat sensor, upon testing I can hear the startup sound but the screen showing just strips, from the rubbish I can sense the system is booting from internet or just flashing folder, the usual sign that no operating system, I double checked the cables and can’t find anything wrong as far as I can tell, but I admit the data cable (the wide cable with lock) may be pushed hard when trying to insert it back, did I damage the screen or the board?, please advise…
I tried to remove and reinsert the cables but nothing changed, it is as it is…
Here is a preview:
Please accept my question and help me, I have no clue without your answer…

Hello guys and thanks for your responding, but it seems that there are some conflicts between my updates and your answers, so here is what I did…
after I swapped the HDD and fall into the screen problem, I swapped back the original HDD that has mac os on it and boot the iMac, the same screen issue continue but this time after the initial boot, the screen went black completely with no back light at all… so I connect the iMac to external Display (my Samsung 50” TV) and I can see the output but it is continuously flashing on & off, the keyboard, the mouse and the system is responding but the flash never stops…
I tried to search in the internet and I notice that many places point to the cable as a suspect so I connect another iMac using the same cable and the output was fine without any flashing…
so the iMac display has the problem shown above and the output to the external monitor is flashing continuously…
the iMac is working, programs and responding but the display is showing as above during the boot after that it turns off when the mac os reaches the log on screen, on the second monitor I see everything but with continuous flashing…
I double checked the display cables and the sockets on the board and they are fine with no visible marks as far as much as magnified as I can tell…
where does this put me…
I appreciate any information to lead me, should I give up or there is something I can replace for sure…
thank you all

here is something new and I didn’t expect it by any means…
today I received another 27” iMac, Late 2012 (EMC 2546) (with a dead hard disk) which is compatible with mine Late 2013 (EMC2639) and I connected the display from that machine to mine (which is suppose to have a problem in display), to my surprise the screen also shows the same symptoms as mine… I also connect my screen (which is suppose to be faulty) to the other iMac and it works perfectly…
So it is not the screen at all, my screen worked perfectly on the other iMac, also an external HDMI monitor connected to my iMac works perfectly which means ??
where does that puts me? what part of my iMac does not work?

You swapped HDD with SSD? Have you downloaded mac os ( or any operating system, that you like ).

No, I was just testing the imac, I just switch it on booting in recovery from internet and the screen was not working from the first start up...

I think, that display might be kind of damaged, because, you had to take the display off. When you opened, the display or placed it back, you could had damaged connections? You should check the connections.
