Problem with video display

Hi, I changed the keyboard ok my MacBook Air, but after remounted everything without problems, everything work fine except the video. It work like some cable in not connect good, or something like that. I checked every connectors inside again and again, but it still have the same problems. What can be the reason? Or, what connector I have to check?

Thanks in advance

Does the screen not come on at all? Or does the backlight turn on but the screen is just black? Or does it display a lot of garbled colors?

Weird issue, haven't seen the backlight do that before!

Unplug the battery and the screen cable, then clean the inside of the screen connector with 95%+ isopropyl, dirt inside could be causing this. Check and clean the cable as well, very easy to chip or damage the gold pins slightly when disconnecting it.

If this doesn't work, I would recommend taking it to a shop who will have a test assembly (to rule out the screen/cable issue), then they can either replace the cable, screen or whole assembly if this is the cause, depending on their skill level. If not this, the issue will be logic board related or software related.
