I would remove the rear housing and test for it. If the issue does not re-ocurr, then either get a new one or try and bend yours back outward. Sounds like its putting pressure on the LVDS cable. Be aware that unlike Apple will (not) tell you, you don't have to remove everything else to do this. If you are careful, you can remove the two hex screws without taking the screen off. Then just use a paint scraper or something to pry it off carefully. Start at the top. Mind the antenna cables when you remove it.
