I have a late 2013 Retina 13" that works fine with a good (but cracked) screen but I'm trying to repair a screen that had some damage to pins 1 and 2 and very slight damage to pins 3 and 4 on the LCD-side connector. After adding solder they all looked good so they were just covered with melted plastic. I replaced the connector and have a backlight now, but no video. I was extremely careful so as to not damage anything around the connector when removing it. Pins have all been double-checked - they're all solidly soldered. I have a known-good cable. Any ideas what could be happening with the signal once it hits the LCD?
