I have a Samsung R522 that I disassembled to replace the DC jack, and while disassembling, I put some pressure on the keyboard cable going to the motherboard while trying to reach in to disconnect it. There is no signs of damage, no kinked wires, no missing connections that I can see, but when I put it all back together, certain keys on the keyboard are not working (backspace, up,left,right arrow keys), it seems as if one of the 10-12 small wires going from the keyboard to the motherboard is damaged (my diagnosis) since most keys work fine.
Now, I'm going to take it apart again when I get home and check the back side of the motherboard to be sure there aren't any solder pads that came up where the keyboard cable slides in, but is there anything else I could check? Is it more likely that the cable got damaged within the keyboard rather then the part going to the motherboard? I'm thinking I'll need to order a new keyboard online, but I wouldn't mind some reassurance that a new keyboard will likely fix my problem.
Thanks for anyone who took the time to read
