iMac a1311 lcd doesn't work

I have this imac that a friend gave to me as one that won't power up. Long story short, I ended up replacing logic board and graphics card , and someone had taken the HD so I replaced that with one that had sierra already loaded. It will now boot with external monitor just fine, but lcd will not work. All 4 LED'S light up and backlight also lights. I got another lcd and backlight inverter with same results. I have also replaced the LVDS cable. I am not sure what to do next and am pulling my hair out on this thing ,so any help is much appreciated.

What happens when you either plug in an external display does it work? Then see if placing a flashlight on the display at a sharp angle are you able to see the faint outline of the desktop icons?

Yes ,works great with external monitor. Tried the flashlight thing but couldn’t see anything.

I cannot see any damage but there could be. I am thinking its probably another bad lcd.

If you look carefully you'll see a slight hight difference on the left side with your second image with is the logic board connector. So the width of the slot has widened a bit which could explain things as the contacts are not making good contact.

At this point I'm suspecting either the display is not the correct one or the LVDS connector on either the display or the logic board is damaged (given the fact you has replaced the LVDS cable already).

As you'll need to open the system again take some tight sharp pictures of connectors looking straight down the slot and at an angle face on from both sides so we can see if the connector is damaged (both). You might want to try another cable to make sure it didn't get damaged somehow.
