the internal pegtron keyboard was not responding well and now totally dead. think i found the culprit is the twisted ribbon cable but there are no nicks.
but maybe the keyboard controller card (blue in the picture above) is bad. is it not possible to purchase that keyboard controller card separately? the replacement system boards (43RD6 - i5, FY1VN - i7 pictures below) do not include that keyboard controller card?
