              well , i really dont know why somethimes im sleepy LOL .. well something must been wrong with this board , after all this changed , this is something for future learning(well i learned this before, but somethimes we try to go directly for component chek and in the end somethimes there is more than this , like the traces , i looked all traces all seems good , in the end very very carefully and only with microscope , notice a gap on a test point , were that testpoint disapear not making contact of one trace , i bet this trace is what is not giving does keystrokes , gonna repair the trace and let you guys know .but 99% sure will be fixed - cheers~
