As your external display is not showing any defects that focuses the issue to the internal display and its connections to the logic board. I fear you may have damaged the LVDS connector on the logic board.

When you pulled the display forward you may have yanked on the LVDS cable enough to distort the connector. Look down into the socket does one side look wider or pulled away?

Looking at your image it does appear the locking tabs on each end are bent out (marked in blue)

Place a [product|IF145-002-4|Spudger] behind the tab so you don’t go to far and carefully press it back down.

At this point I would roll out the oscilloscope to see if I see any ripple on the LED backlight board. You’ll also need a LVDS, V-Scan power & thermal sensor extension cable set so you can have the display active on the system and yet full access to the internals. Do you have the schematics and board views? You’ll need them as well.
