Ok, I would not! Advise this as something to do more than a few times but! http://tinypic.com/r/64qr11/5 where the arrow is pointing, Run a conductive object such as a small screwdriver from pins 1 to about 10, If your machine works in general it will power on, If this does not work the first time don't be disheartened, Try once more but slowly.
Just behind the panel is the display sided LVDS cable, what you will possibly find is that you're pressing the display back into shape stopping the cable from being trapped, If the machine was dropped or bumped (by the looks of it) Then this or many other display related issues are probably the case.
Hi, Sorry to be the bearer of bad news but it seems to me like there is a possible display issue (Obviously) If you can check on the board or on the display module cable you might see that one of the connector plate if not a few may be ever so slightly damaged. Check along the ribbon and look for snags or possible breaks too.
